Costco 6V Golf Cart Battery For Your RV or Trailer - Affordable Off Grid Power 

Amp hours?

Originally had 212 V batteries. Purchased 2 6volt Golf cart batteries from Costco best purchase I ever made.

I was at Costco yesterday in Gilbert AZ and the batteries were $93.99 with a $15 core charge, still a good dEAL.

After reviewing all the options, went with the Costco’s thanks for the vid.

nice and precise explanation...looks like costco six volt batteries are on my shopping list

I also have the Costco batteries. They are great bang for the buck. And I invested in the carry strap you mentioned. Glad I did, it’s very handy.

I see that you have a battery monitor in your trailer - my truck camper did not come with one. I now understand that they’re essential for avoiding excessive discharges (duh!) and improving battery life. I’m installing one next week. Dipping only to 5% discharge before recharging is harmful-as is regularly discharging below 50% of capacity.

Thank you, thank you, thank you... for acknowledging that golf cart batteries can be deeply cycled. You are the first person to actually state that fact on RU-vid. Thank you again.

NO they're designed to go to a 50% charge and then you charge them up... in an emergency you can take them down to zero but I would not recommend it

I like the nife battery's...can drain them down to 20 percent with no problems and they last for decade's....

Recently came across your channel. Good content, keep it up.

Looking to replace my Travel Trailer 12v battery and was thinking about going the 6 volt golf batteries in series this time. I've never used the 6v golf batteries before. My local Costco has the Interstate 6 volt Golf batteries for $98.93 each. Not to bad a price still, but there was several negative reviews of the Interstate batteries not lasting very long on the Costco reviews. A lot of negative reviews saying the batteries only lasted less then 2 years with regular maintenance . The warranty is only good for 1 year.

put a washer under all the nuts , you will have a much better connection

Costco battery (Johnson Controls, mexico) are still a flooded type battery :-(. You want hard working, long lasting, low self discharge battery? Go AGM. Mount them any way you want, upright, sideways, upside down.... Yes, AGM will cost you a bit more, but they will self discharge WAAAYYY less, charge much faster, and will out perform a flooded battery any day. Bonus: no acid to leak, no internal plate corrosion & collapse. No checking any fluids with AGM, period. Back up your AGM battery with a solar array on top of your trailer/coach, and just forget it :-D, years of hassle free service. Great channel here.

I notice no one ever says you have to cut the amp hours in half because you can only discharge then 50%

like this simple improvement of battery replacement with golf cart equivalent. You may want to caution about discharging batteries too much. as with all LEAD ACID batteries you can only discharge to half the rated capacity; before you recharge them fully. Else you will loose the ability to get that back. So 220 AH will only get you 110 AH actual use (it sucks but its true). Many will use a charge monitor device for $100 that displays current used and voltage in an easier monitoring situation. If you dscahreg more than this, your batteries will only recharge to maybe 80% capacity next time, and worse the time after that.

Yes per battery.

I've got six of them wired for a 12V inverter and they don't seem to have enough juice. Going to wire in two more and just use the crap out of them for my off grid place in Cabo and hope for the best. The rating on the 6V golf cart battery is 110 CR which doesn't make sense. Seems extremely low for a GC2 battery. These are NOT Interstate...fairly sure they actually have a Costco label on them. Yes, they're like 60 lbs each...not light.

Exactly what I need to get for my travel trailer. It has always had one 12v battery, not enough power for furnace, water pump, and a few LED lights.

Bro, do you have kids? If you do, when you tell them to do the dishes.... what do they say? ..... "DoitYourselfDad!" Baahahahahah!! Nice battery swap BTW

Good job on the viedo, very helpful.

I have a similar fun runner. How do you get your power chord/hot cable that long to run to the opposite battery? Mine are too short from the factory

When there is no Ampere-Hour or AH rating on the battery but a Reserve Capacity or RC rating, you can turn that rating into an AH rating. The RC rating is defined as the number of minutes a fully charged battery at 80°F or 27ºC will discharge 25 amps until the battery drops below 10.5 volts. The RC rating provides an indication of the time that a vehicle with a normal electrical load will run for if the charging system (alternator) fails. To convert RC to AH rating at the 25 amp rate, multiple RC by .4167. The battery has both the RC and AH at 20 hours written on the label. Even allowing for Peukert's Law (Google it) kicking in... 105 X .4167 does not equal 220! It's actually 43 or so AH. You've been had.

is this on solar?? you should say more of what your putting out here on yt... da ya think??

I have been looking at the LiFePo4 batteries but I just can't seem to get over the $1,000 each price tag on them.

How tall are these compared to normal batteries? Will they still fit in the standard camco battery boxes (that's kinda what those look like, but can't tell for sure)? I can't find dimensions for them anywhere...

Excellant

I also used 2 x 6v Interstate GC2-ECL-UTL Deep Cycle Extreme Batteries. The specs says 115 mins @75 amps 225 Ah @ 20 Hr. Do you know what do they mean?

How much solar do I need to 'em charged?

Does it matter if the - lead is longer than the + lead?

Can i use telecom batteries for solar set up? Tnx!

Isn’t two 6v 50ah is same as one 12v 100ah for example? Stream of power voltage is different. But doesn’t really increase capacity??

Great information, thanks. Could you expand a little bit on the hookup? I'm a newbie, so not familiar with how this all works. I see how one battery is connected to the other, but looking at the battery on the right...what is it attached to? Thanks

Are 2 6v Golf cart batteries in parallel better than 2-12v marine batteries in parallel? I would think that 2-12v's would last longer or no?

"My old ones were probably 10 years old". Right, they were not from Costco. You will be lucky to get 2 years out of the Costco 6 volt batteries. I am on my 3rd cycle of them, and they last @ 14 months. I kept thinking that it was me until I did some research. Check the reviews on the Costco website, and you will see that the only positive reviews are from people who just installed them. Those of us who have used them for a while do NOT recommend them. PS: The "Interstate" label is just that. Made by whomever gets the contract....

Just a heads up! Got off the chat with a Costco chat rep. They do not list RV batteries on their website.

These are branded Duracell at Sam's Club - $87 each + $18 core. 215 amp hour each, so in series you get 215 useable (430/2). Just installed in my class C... Under step, but had to modify to raise step about 1". There is NO 12 volt deep cycle that can come close.

This whole wiring in 'series' isn't making any sense. How does running a Positive to a Negative NOT spark, short out and burn the house down? Hasn't anyone ever hooked up a battery charger backwards, or even hitting the power wire of a 12v light to a piece of metal? Everyone's doing it, but it just doesn't make sense. I truly don't understand how you can hook up a + on a battery to the - of another battery. I run 4 batteries our semi's and you don't DARE touch a + to that of another batteries -. Really bad things happen. Someone please explain??

i like your videos

Are you sure it’s positive on battery 1 to negative on battery 2? Other videos say connect the batteries parallel + to + and trailer’s + wire to battery 1 + & ground wire to battery 2 negative. Maybe there’s more than one correct way to do it.🤷🏽‍♂️

What is the Amp Hours rated on these batteries?

You do t compare same type batteries just because they look a like!! Why don’t you actually be more helpful and compare their amp hour ratings! Something a lot more useful to RVers relying on solar and batteries for long ten use and not the fact it’s cheaper. They are cheaper for a reason! Quality and specs both! Your older US2200s are far superior than these interstate/Costco ones.

I looked into the 6v Interstate golf cart batteries on Costco.com and they have very poor ratings. Most say they die shortly after the year warranty.

How many AH are these 6 volt batteries? Thanks. Ken

I'm doing a Sienna minivan conversion. Realistically, could I have these batteries inside the van - probably under the bed? Or do they really need to be "outside the living area"?

I had a full set of six. The terminals melted right into the battery. Happened to my neighbor too. Buyer beware.

So I have two Interstate Batteries cost me around $500 232 amp hours each battery so it's a total of 464 amp hours for 500 bucks to get the same amount buying Costco batteries at 110 amp hours it would cost 910 bucks

Its been 2.5 years. are they still working OK? the Costco reviews say these batteries suck. ★ 1 out of 5 stars. Darrell · 4 months ago Not good I bought two of the golf cart batteries two and one half years ago for my RV, and after the first year they started to fail, I thought I left the power on, so I put them on the charger, they would not hold the charge, long story short it turns out most people that have purchased these have the same problems, they should last at a minimum 4 years. Costco needs to go back to interstate batteries and find out what the problem is and give the consumer some relief, and stop selling these, they are no good. ✘ No, I do not recommend this product. ★ 1 out of 5 stars. Miguel · 6 months ago Terrible batteries I purchased 6 for my golf cart and before the year they started to not hold a charge. Returned them just prior to 12 month warranty and got a new set which lasted about 14 months. I was just outside of the warranty period and tried to return to Costco and they said the warranty was only 12 months. I am aware that the warranty is only 12 months but the batteries are really poor quality and just die just after a year. They where aware that I had previous issues with the first set I purchased. Ive been a Costco member for a long time and they usually carry great merchandise but these batteries are not up to Costco standards. Costco is aware the batteries are poor quality and should give the customers a credit when they are selling faulty items like these 6 volt batteries. ✘ No, I do not recommend this product. ★ 1 out of 5 stars. Yupp · 6 months ago Didnt last long I guess mine lasted a little longer than the other reviews, but still not long enough. I bought 4 of these 26 months ago for our rv. They were well maintained with solar panels, and stored during the winter. If I would have known I would have only gotten 2 years out of these, I would have paid another couple hundred dollars to get the Trojans. Hopefully somebody else can learn from my mistakes because of this review. Oh well..... you live, you learn. ✘ No, I do not recommend this product. ★ 1 out of 5 stars. Mike · 9 months ago Worst Batteries Ever These lasted only 18 months with occasional use in our golf cart and I was surprised to learn their warranty is only 12 months. Previous sets of batteries have lasted 5-6 years easy. I love Costco and wish they would find another battery line to carry. ✘ No, I do not recommend this product. ★ 1 out of 5 stars. elha · 8 months ago Dont waste your money If you think this cheaper battery might last maybe 1 year less, dont. 2 golf carts in both cases original batteries lasted 7+ years, in both cases these lasted 4-5 years tops and last 2 years were miserable. In both cases they were well maintained and stored. Costco missed mark on these and offered nothing ✘ No, I do not recommend this product. ★ 1 out of 5 stars. Rory · 8 months ago Terrible battery life Bought two for our RV. They have a 12 month warranty. Ours lasted 14 months and totally died. Costco wouldn’t refund any amount. Do not buy these! ✘ No, I do not recommend this product. ★★ 2 out of 5 stars. WearyTraveler · 3 months ago 14 months... The 4 in my RV are 14 months old and they’re starting to not hold a charge. I haven’t had them tested but they’re gonna be toast soon... ★ 1 out of 5 stars. MACC · 9 months ago We bought 6 of these for our golf cart and they didn't even last 2 years. The batteries we replaced lasted over 6 years. ✘ No, I do not recommend this product.

...who says "these ones?"

Your video is 5 years old (pre-pandemic) - you need to update this video or take it down. Things have changed.

these ones.....really?

first thing that will make me stop watching a video... breathing. if i can hear you breathe while someone else talks, done.. seriously, 2 seconds is what I will give.. second thing. the back of your hand... I'm not here to watch the back of your hand move around pointing at shit.. I wanna see the batteries and maybe point at the terminal or some crap every once and awhile, but if it's a waving it around just to see the hairs on the back of your hand move video... i"m out!!!
