As a forklift road tech (been in the industry for just over a year now) I love these videos. I know RU-vid pushes creators to make reels instead of long form videos and I do love your content, I would love even more to see more forklift/industry videos like this more often. Your video on replacing a Toyota radiator actually helped me immensely as I’ve had to do that a few times now and would be doing it the dumb way to this day. Either way, keep it up and best wishes from BC, Canada!!
Great video and me living in AZ. there are lots of golf carts and most people I know change out the set when one goes bad. I had been running gel deep cycle in my wheelchair (2-12V for a 24 V system) for years and I got about 3 years out of them but when one goes bad, replace both. $300 each. My new chair came with Lithium and what a difference. My range has almost doubled but it came at a cast. $5000 but I am able to go all day without running out of power and should last the life of the chair. (about 5-6 years) I am very active in teaching and building furniture,, and unloading trailers so The new batteries have made a huge difference
The lithium batteries are definitely an improvement over lead acid but as you mentioned they’re a little pricey. I think as far as commercial applications go lead acid batteries will be around for a while.
I work with these batteries on a daily basis mainly on scissor lifts. A few quick checks during the daily/weekly inspections no one does. When checking levels in each cell, before blindly filling, look for extreme differences in water level. IE one will be at a normal use level, one will be down to the plates and one near the top of the cap; usually accompanied by wet tops of batteries or complaints of leaking batteries. One cell is feeding the other it’s water. Thus being bad. I have had luck finding the bad egg in the bunch by plugging in to on board charging system and check voltages while being charged and have found one to be charging at a very high rate. Strong sulfur smell is sign of over charging as well. The hydrometer can throw people off some times if you don’t burn off that “top” charge after being connected to a charge system. I do have one of the expensive load testers that’s will test at 75amp for 120min ( I think but most don’t make it anywhere near, maybe 70-80) it is nice to have but with time involved sometime it can be a pain to pull out unless trying to give the customer a relative estimate of life of the battery left. We use distilled water but our jobs never have that on site, who can blame em. Just yesterday I got to a job and one battery had the caps off just sitting on top of the battery and water was non existent down to the plates. Any water is better than no water.
Your voice is calming to me when I'm real stressed. Thanks for making these long format videos so I can come back when needed..thanks for everything you do, I don't know if you'd be surprised but they are helping my mental health tremendously.
I tried to explain that to my ex once, when she was "helping". I think she thought I just wanted her to get naked when I was telling her to get her clothes off and in the washer fast.......🤣. Swiss cheesed those jeans that cost three times what a pair of mine do, for 1/3 the fabric.
I have dedicated acid pants which over time will become fishnet trousers , again it's a mystery since I'm not juggling the stuff but yet the holes appear no matter how careful I am with it.
Another great video bud. I'm a nerd and a shade tree mechanic/fabricator from near birth, run some big construction work, had my head under the hood of about anything at one point or another. There are a lot of guys making DIY vids, sometimes I watch them just to laugh at how their great new ideas just aren't, like you guess lol. Buddy, I watch yours to learn something.
Another difference between starter batteries and deep-cycle batteries (at least the ones i've seen), the deep-cycle batteries tend to have a larger "trough" underneath the electrodes so that the crud that eventually flakes off have somewhere to go where they don't touch the electrodes, so they don't self discharge/short cells. Sidenote: as far as i know, the recommended depth of discharge is ~50% of the capacity if you're aiming for maximum longevity, but it's probably going to vary on how fast you're discharging them etc
Thanks for the content. For capacity testing I got a “A10H” cheap-looking electronic load on eBay for $80. I blew up one of the power mosfets because they advertised 30V but the mosfet was only specced for 20V, so I replaced the mosfets and it’s good again. The software has graphing, capacity totaling, and programmable voltage cut-out, in addition to charging modes. Great for both lead acid and lithium and the best option I’ve seen below the serious $300+ options.
Very detailed and entertaining video 👌🏼 I’ve been in the forklift tech industry for 8yrs here in North Jersey & mainly deal with Toyota & Mitsubishi forklifts gas, LP, diesel, electric. Enjoy your forklift videos/vlogs Would love to see more of them!
I have migrated away from the toaster style load tester to a digital tester. Specifically the Topdon BT300P. It load tests, gives a state of charge and overall health in percentage. It can also do charging test and cranking test for auto application. It can also print out results. Ive found it very handy and more thorough so far.
Really good advice! At work we run some scissor pallet jacks that have normal car batteries in them because they are cheap. The batteries only last about a year and capacity deteriorates very quickly. Not a good idea to do that.
The thing you got a remember to with the scissor lift is the weight of the batteries are part of the stability. I’d have to fail a scissor lift on inspection that didn’t have the right batteries in it.
Heavy highway trucks and off-highway equipment are typically wired in parallel. Although, back in the 60s, or so, they were more typically wires series. Dielectric grease helps prevent corrosion on the posts and cables, too.
I feel so cool right now. I run the cart shop at a golf course, our fleet consists of 70, 2016 model year Yamaha 48 volt golf carts. Each cart has 6 batteries. The ends that bolt to the terminals always corrode off so we clean the battery tops with water, baking soda, water, then compressed air. Spray fluid film on the ends once you’ve done that they’ll last for a long time. My theory for why the ends corrode off is because the batteries get overfilled and vent excess acid onto the terminals and ends, or it’s because they run hot.
I had a friend lose an eyeball when he messed with a battery somebody had put on a charger. Also saw my neighbor's motorcycle battery after he boiled it dry on a fast/jump charger, thankfully no injuries there, just the battery suffered. Be safe.
I had a crack in the battery in my truck when I was in college and it was slowly leaking acid. I would top it off with distilled water occasionally because I had no money and I like to procrastinate. One time when I put the cap back on, a bit of acid/water shot directly into my eye. Would not recommend. I washed it with a ton of water and my vision was blurry still so I went to the ER. They flushed it with several bags of IV fluid. The outside layer of my eye was eaten away but it healed and I fully recovered. Definitely scary and dumb.
Lead acid do not want to be discharged. Do not run them low if you can avoid it. If you use it, charge it. A light float charge is good for them. Look at car batteries, they run a starter motor that runs for 2 seconds then they recharge. Deep cycle are they same chemistry with basically thicker plates to deal with deep cycling. They don't like it, but they can do it. Keep them charged and keep water in them.
I have to disagree, I work for a battery company and we were taught the best for v force deep cycle batteries are too bring them to about 20-30% discharge and than let them get a full recharge for the best bang for your buck, that’s straight from the manufacture to. With that being said yes keep them watered.
@@matthewmeneses8459 oh yeah, that's the way to get the most use out of them. What I'm saying is using them at all shortens their life. The best life they can live is a slow float charge without ever being discharged. But then there's no point to the battery. Discharging them shortens their life but that's what they're for. You don't need to discharge them 30% but it's probably the way to get the most use out of them.
Thanks for the info. None of my batteries have the ability to be filled back up. I have 2 100amp batteries for my solar system. They recommend using deep cycle for solar. Any way I have had them for years and they are starting to loose capacity. I am thinking about getting 2 new batteries that are 200amp so will have twice the capacity. Anyway thanks for the info.
@@FunkFPV That's why there are still LA batteries in all combustion engine cars. For me, it took a useless slow junk, and converted it into a super fun long distance moped.
I have a deep marine battery in my Jeep Grand Cherokee that I hook up a power inverter to sometimes. And it's nice to run my house off of when power is out. But I refuse to let it get below 12 volts because the alternator would not like that recharging in voltage lower than that. Brushes can start smoking
My youtube suggestions are being flooded with tool stuff i dont even understand since watching your videos. "oh you like funk? heres the history of craftsman and harbor freight tool guy"
Those are about $160 bones each, and use them in my bus conversion. I have a watering system for mine, all the caps have hoses that connect to a common manifold that fills them equally and simultaniously.
Those are great but it’s a good idea to pop those caps off every once in a while to make sure they’re all getting filled. I’ve seen a few batteries cook a cell because it wasn’t getting any water.
@@FunkFPV yes, your correct, too friggen expensive to fully trust a Chinese or pakanstanese, india-neez or where ever the fuk-aneez they are made product to do the work for you!🤠👍
OSHA - you need gloves and glasses and a shower kit and a spill kit and eyewash station and fire extinguisher and me and the boss with the forklift battery- you hold the funnel, i'll pour the shit in
There are these cabins up by a pretty remote lake in my area. I knew one of the owners of one of them and he would pay me to come out and maintain his property mainly his generator and his battery banks because everything is off grid up there.I would do some plumbing or painting or whatever else too. But because I had keys and access and knew where everything was, other people who lived in the same area this guys neighbors started calling me to have me do the same thing sometimes they would want me to work on their little zodiac boat outboards or whatever too. I basically paid my way through college doing that. Everybody was willing to pay a bunch of money because you had to go work up in the mountains Bring all your own tools and not be supervised and to be honest people that own lakefront vacation homes have money to spend apparently. I used to go up there every month and just check everybody’s batteries, they all kind of liked it because I go up check the batteries make sure the house hadn’t flooded or burned down (one guys did flood that was bad another guys was hit with a tree). Every once in a while somebody will buy a house up there and they’ll see my invoices and they’ll call me, It’s not economically feasible for me to do the work anymore but I do know a guy so good times
Knew most of the things Funk presented. And watched it for entertainment. Still learned an unofficial rule (rule of thumb) about the acidity 50 points-ISH of difference between cells (on an instrument with 1.3k graduations)👍 Now i feel the urge to buy a float battery acid tester 🤣 I'm joking, i don't come in contact with flooded batteries.
You should do a leatherman pliers review. Although I also understand that a leatherman costs way more than a 22 dollar piece of junk from China but idk it’s up to you just an idea. Maybe use one with the replaceable cutters so it’s less expensive.
Here in the UK for along time now we have had maintenance free batteries. Have you ever heard of them and are they mendable? I have looks around for the old fashioned type bu they are getting really rare and, as such, too broken repair. Thanks.
So basically, the voltage is the power, and the amp-hours is the time the power can be provided, right? Didn't know about series-parallel but it's well explained here.
Didn't know that about short charging lead acid batteries. That's the opposite of modern LION batteries. Lead Acid batteries are still very good in some applications versus lion.
"I colored mine blue uhh to match my balls" I'm dead dude. That's 3 videos in a row you've slid in a joke that hits at just the right time. Subbed till RU-vid explodes. Are you on Rumble or anywhere else?
I've always thought it's a good rule of thumb to have two multimeters one that stays in my toolbox at home and then I have another smaller one that stays in my truck's glove box
What grinds my gears? Chinese electric scissors or booms that you never know how it's wired. Nothing the same. Also the batteries that are for certain model scissors that are extremely expensive because of the weight requirements.
you can get good advice from youtube, if you can weed out the wheat from the chaff, and there's a lot of chaff, the silliest chaff is the free energy crowd !!!
Those 100 amp load testers are nothing better than a hand warmer. Batteries are to be tested at half their CCA rating, meaning if it is rated at 100 CCA you need to test it at 500 amps. If the battery does indeed fail a 100 amp test it is 100% degective. A 12 volt battery rated at 1000 amps sould not drop below 10.5 volts with a 500 amp load for 15 seconds. FYI, going on 30 years repairing HVAC, refrigeration, generators and electrical systems on commercial fishing vessels and large yachts with 24, 32 and 48 volt DC systems. AC systems are 220 to 480 volt 3 phase.
I have a 8series Toyota that has a new battery and starter , but when the units key is switched off it tries to crank . I tested the switch the switch tests good. Any ideas?
Load testing of deep cycle batteries is not a one size fits all thing. The load is different for different batteries. For accurate results always consult the manufacturer. Too many times i see people just take out the 100 amp load tester and use it on every battery they test. This is wrong. The load and duration of the load needs to tailored to the battery under test and then the result needs to be temperature corrected. Yes the result will change based on temperature of the battery.
"I've got acid in my eyes tons of times." He said without wearing safety glasses. I wear safety glasses religiously, and I've been to the doctor for eye issues more times than I can count and they can't figure it out... Maybe I shouldn't bother.
I use safety goggles, not safety glasses. Goggles have a seal around your entire eye area and dont let fumes or dropplets in. I was real happy with FPV's safety talk prior to the work. 🥸
Pff who needs Google reviews when we have Funk FPV?! Answer: nobody 😎 ......unless of course you're wanting to check on something that's not the handfull of things he's reviewed or commented on.... then yah those reviews are helpful.... but FUTC pliers? Pfffff 😎
Alright dude. The shorts were funny in the beginning, I'd personally really rather see the "day at work" mechanic stuff. That's far more interesting than some far east idiot trying to weld with a wooden stick.
Don't fully fill your empty batteries! Make sure there's maybe 80% fluid, otherwise you get acid overflowing. Also ion exchanged water is enough for batteries, it has under 10 mS conductivity, tap water starts from over 100!
It's such a shame that your long videos don't get nearly as much views as the quick snarky shorts (not that I don't find them amusing but it's just reacting to intentionally poor content)
