Here's an old vintage battery charger I recently saved from the garbage. It has the same problem pretty much ALL these old chargers have, but we'll fix that and add some safety features. These are great for charging lead acid or sealed lead acid batteries (SLA), and can often charge batteries other modern chargers won't even attempt to charge, so they have a usefulness and should not be discarded. But how SAFE are they? Let's see how we can repair one and make it safer at the same time.

I would have put that rectifier on that aluminum plate because aluminum is the best heat dissipator. If you take a big chunk of aluminum and heat one corner eventually fairly quickly the heat will travel clear to the other side you could do the same thing with cast iron and it takes forever for the whole thing to get hot. The more you know public service announcement

I rebuilt one of these exact same chargers years back with bridge rectifiers. I wired two rectifier’s in series to get a voltage drop to get it more in line to what it should be. I believe you get about 1 volt of drop per rectifier if I remember correctly. Kbpc5010 is what I had on hand and what was used in my application. It was a charger for a friend of mine who’s dad used it when he was younger and passed away . His mom and dad owned a western auto in morehead ky several years ago. He still uses the charger to this day. Great videos! I really enjoy your amp repair videos!

@PrinceWesterburg 2 года назад

Wow, thats odd - I just took two vintage battery chargers apart as they both had 3A-4A 6v transformers and I'm short of filament supply transformers. Oh well, part of my grandad's stuff from the 1950's will live on!

Even if the transformer was trashed, the chassis would make for a very cool guitar amp. A push pull 6AQ5 setup would be right at home in there!

Good job buddy. Nice rectifier upgrade. (Not to be a cridic, but) i would have left the cardboard and the aluminum plate just like they had it. That would have made a great heatsink (insulated from the outer case) and your idea about a small electric fan , would be a great upgrade. I'm currently restoring/upgrading A similar little charger. Glad to see im not the only one who would rather fix an oldie than buy cheap plastc replacement . 😁👍

@DuffusMonkey 2 года назад

Great Idea. I have a newer SMART charger that the smart part doesn't work very well anymore. I might just have to bypass all of that and convert it to use an old style Timer. Lawnmower batteries always seem to get so low that I have to jump it to another battery to get the voltage high enough for "Smart" charger to work on it. I am old enough that at the Full Service Mobile Station we used to have to add acid to new batteries then charge them before we could install them. We had a monster charger that could boil the acid if it ran too long. But if you had a REALLY Dead battery you could boil it a few times and rejuvenate a battery that otherwise was complete junk

@sthildas4857 Год назад

Most of the classic old chargers will charge a flat battery, not like the more fancy types nice fix. 🇬🇧

@dammitZeva 5 месяцев назад

With the newer type chargers you can still use them on extremely dead batteries by 'jump starting' them. The charger has to see a voltage above a certain level to be able to start. Jumping another 12 volt battery that is good in parallel to the bad one gives the charger a good starting voltage that it likes and then the charger starts working. Then you can remove the jump start battery off and the charger continues working. I had to do this trick a few times when I let my tractor's battery set too long and the voltage got too low.

@gumbomudderx7503 2 года назад

I just bought a vintage old Schumacher battery charger last week, so this video is pretty timely! I really hope more of these get saved than tossed! Newer battery chargers have digital circuitry that will sense how much charge the battery has in it, and if it’s totally dead then it won’t charge it. That’s worthless in my book. I need to be able to charge dead batteries, not just low ones. *edit* I commented before watching the whole video and just got to the part where you mention circuit protection on the newer chargers 😂

@allenrusselljr 5 месяцев назад

I just found a 10 year old Schumacher on top of a dumpster. It's new enough where it has a lcd screen but it's not a smart charger. I actually had a similar one for years and used it on my mowers / quads and car. This one is not working, it reads 0.0v on every battery I've tried and makes a quick arc/pop when you first plug it in. I'm far from skilled when it comes to diagnosing and repairing electronics but I'm starting to learn.

@cantyouhearmeknocking1961 2 года назад

I bought a Western Auto brand 12/24 V battery charger with auto/manual modes that was $21 shipped to my house. I use it to charge my boat, riding mower, & spare car batteries, & so far (1 1/2 years), it works great. I had an older charger that also worked great, but I sold it along with my old bass boat. I had that thing for over 20 years. I doubt this new one will last that long, but hey, it was cheap.

@TheGuitologist 2 года назад

This one could be converted into a 12/24V by not using the center tap and going with just the bridge rectifier.

@kevinshea4776 2 года назад

Insert a car brake light bulb in series with the output to current limit the charger. The bulb will regulate the current going into these smaller AH batteries. Place a switch across the bulb to bypass it and get the full amps out for larger batteries. Great video!

@whiskeysquiker Год назад

I have two different similarly styled chargers like these. Neither work. I inherited a ton of vintage tools and I like the antique look of these which is why I held onto them. Analog devices are good to learn on, too. This was quite informative. I'll have to add new ammeters to them both, as well, since to plastic lense was missing on them both. Needle on one as well. . The reason I'm interested in fixing them is like you said, they're dumb. You can "overvolt" a really dead battery as long as the amps stay reasonable and it will help to desulfate the cells. Just gotta monitor their temperature and make sure you don't explode them. But if you desulfate, discharge, repeat a few times, batteries that tolerate load tests, but maybe can't hold a charge well can be restored and their life extended significantly and I, for one, am tired of dropping a couple 2-3 bills on new batteries for all these cars, food truck and trailer, and devices. Our president seems hellbent on crashing bicycles and economies but he's all outta bicycles and we're feeling it pretty heavily. I looked into getting a desulfator, too, which will be a maintenance tool, but some of these batteries I have will need more juice than what these damn smart gadgets will push. Good vid. Appreciate the time you took to explain certain things that my knowledge of is lacking in, though I have a good understanding of the concepts.

@srtamplification 2 года назад

You get higher DC voltages with a bridge vs. a full-wave. Also, with a bridge you don't need to use that center tap at all.

@TheGuitologist 2 года назад

Without the center tap, the voltages double to 12/24V.

@srtamplification 2 года назад

@@TheGuitologist Yes. In this instance you had to, because the original used full-wave. Maybe I worded it incorrectly.

@m.g.540 Год назад

Picked up a old charger too , same selenium diode setup, changed to a bridge rectifier, two AC transformer input leads to the selenium diode array, one DC output from the selenium diode array, I checked whether it was the + or _ then plugged into the bridge rectifier the same polarity and then plugged AC inputs in to the bridge rectifier, one DC output was unattached, charger runs at 15v high 10v low setting, amps is increased overall from its original output, thing will charge up cinder blocks now.😂

@danielsaturnino5715 2 года назад

Hmmm - edit Center tap - you use full wave rectification (2 diods) No center tap you use full wave bridge (bridge rectifier) Is this correct?

@TheGuitologist 2 года назад

You can use a simple full wave rectifier either way, but you can only use bridge without center tap.

I had an old Shumacher Deep cycle charger for 15 years and it was probable that it was 20 years old when I got it.MADE IN USA.Since I use deep cycle marine batteries for my pool vacuum( similar to a trolling motor with debris bag).That finally gave out 5 years ago and since I have went through 5-6 harbor freight models that are all circuit board 's and weigh about 3 oz.Junk the copper is diluted down and they don't hold up.I have recently found in the trash a older Heavy Duty Duralast Walmart maybe? I did buy a NOCO electronic type and 2 years everyday and still charging! I'm suprised.Ace is the place.I have never been let down by finding what I need to rig almost any project.The reason I added last comment you were just talking about Western Auto and True Value which I miss.Ace is of course outsourced from China these days but you can get help if needed!

@laserflexr6321 4 месяца назад

mmm me thinkseth you would have done a lot better to put the aluminum plate back and used that for heat sink. That thin steel case will not conduct heat away from the diode very well. I will bet that if you load that heavy enough that the output pulls down to 8 volts there would be 100degF difference in the diode temp on .090" aluminium versus .026 steel. Mounting that on thin steel might actually be worse that having the diode floating in free air so it can convect away the heat. It was a fun gag to swap the manual rake on a wave solder machine. It had a pool of molten solder that the boards would travel across. You needed to rake off the dross and gunk to expose clean shiny solder occasionally. Stainless steel was good, but if you swapped in an alumium one it would burn the s*** outta your hand, HUGE difference in thermal conductivity. A couple upgrades for a good dumb charger like that. One is a fuse holder with the cap so you can replace it without taking all the screws out of the case. The other is a switch and a bulb in series on the DC side for current limit so you dont blow the fuse by overloading the output. Run it current limited until the battery voltage comes up as indicated by the bulb getting dim, then switch the bulb out of series so you can achieve full DC output without voltage drop. I'm in the market for a good ole dumb charger like that cause I am sick of the smart one that are so educated they dont wanna do any real work, especially when you need them most.

Cool, coincidentally i found one of these not long ago, Lester Electrical 24volt 5 amp lead acid charger, looks old but not as old as this one, like has wooden supports in the transformer, but definatley from a more recent time, and its only putting out 12 volts. I thought this was the video to help and it does offer some insight but seems to have smart protection thats smarter then me so I'll just have to leave it alone. There was some old japaense wooden plates with it too, just dumped in an alley parking lot, some wooden shoes too that looked like art pieces, no wonder the Japanese have a good reputation with guitars , they seem to know how to work with wood.

FYI in the automotive World a 12 volt battery gets charged at a rate anywhere between 13.7 volts and 14.7 volts to be optimal. The he more you know!

If you don't like Walmart, don't dream of Target. Walmart has great Super Tech fluids. Target doesn't even sell a single oil filter.

I was taught in highschool auto shop to never leave a battery sitting on the ground. It might not be a good thing especially while charging

@yqwgjsg 2 года назад

I was taught that too at my dad’s gas station. We always sat the battery on an old wooden Coke case.

Don't know what the oldest 'Old Wives Tale' is, but that ones gotta be close!

@markbaker1843 Год назад

Count me in believing that is total old wives tale fiction. Most OLD cars & tractors I've ever seen, the battery box bottom was none other than conductive steel, which generally conducts way better than dirt or cement. Now then, with that said, if the battery has all kinds of crud and dirt all over it, it might be possible for all that to when damp somewhat form a semi-conductor. Even in that instance however, battery is just going to short presumably the path of least resistance being the shortest distance between the terminals on the top of battery (or side as the case, pun unintended, might be). Set your plastic case battery on just about any kind of surface your heart desires, including shiny copper foil & have a happy life my friend.

I got an old charger like those..since the 70's..it is " automatic " ( you can leave it hooked up without much worry - common sense says to not leave it indefinetly !! )...12 V only .. it has no guage to know what it is doing..lol 1 1/2 Amp charge rate..... i have a couple newer chargers..80's versions..Automatic...one has 6 Volt/12 Volt ..the other has only 12 Volt...one needs a look at as it seems to not charge properly?? not sure yet but i stopped using it on batteries ... both have low and high charge rates think 2/10 Amps ? i bought some Fancy New ones last year..got Digital readout on big one..it has dual Amp settings think 2/15?? and does AGM batteries as well as Normal & Deep Cycle...has the reconditioning mode and tells you Percentage /% of charge before and during charge and shuts off but maintains if left connected...i bought a similar smaller charger ( same brand ) for my smaller batteries ( it does full size too ) and can be left connected always....or has quick connect leads to put a permanent hookup on small batteries... they work so much better than my older chargers and have saved a few batteries my old chargers couldn't revive ..( they charge but they also didn't hold a charge long ...new charger got them useful for temporary yard use ..)... some old batteries i had never revived...too old... depends what you want...the newer batteries are junk compared to 10 plus years ago batteries...
