Lets See Your Battery Chargers !!!

[Thumper68]

I was putting together this light/ work stand and had a old charger laying around so decided to incorporate it into the stand.

I understand what you were saying. I was just curious how a little charger puts out more amps than a bigger heavier charger? Do they work on different technology? I don't know a lot about chargers.

Simplyfied explanation: Old school chargers used a normal 50/60 Hz transformer followed by a rectifier bridge (4 diodes) + simple analoque electronics for controlling voltage/current.
Modern chargers use "switch-mode" supply, where the transformation between mains/12V is performed at a higher frequenzy, making the transformers more efficient (smaller iron core, less copper). Some have cpu controlled current/voltage, de-sulphating programmes etc., like the C-tecs (designed in Sweden, made in PRC). Basicly same technology used in most laptop psu´s, cellphone chargers etc. Short story: Before the electronics were the expensive parts, now the copper/iron in the transformers is the expensive part. Same evolution seen in MIG/TIG welders...

Does this count?

Here's mine. I had the charger then found the cart with the tester on Craigslist. Paid $50 for the cart and tester and $100 for the charger a few years back.

Nothing as fancy and sophisticated as most of you. I got a vintage DAYTON from the late 70s, and a FERVE brand, probably as old or older, that is made in Spain. Both work and look as new.

Scored this yesterday:

Guessing late 50s to early 60s. Filthy when I got it, but it cleaned up really nice. Had to repair one connection inside and put a new Heyco strain relief on the battery cordset. And it gave me a chance to use a clutch-head screwdriver (cover screws) for the first time in a very long time.

Works good.

Here's my old Schauer. I've got another, newer model Schumacher around here somewhere.

Once again, my chargers are not worthy.

Scored this yesterday:

Wow! That's a beauty.




Yes, I had to quote that photo.
