Inexpensive reverse polarity repair

Reviewer: from OXFORD, MS US

If you do accidentally kill one of these by reversing the connections to the battery, you may be able to fix it inexpensively. To open the case you'll need a tri-wing bit. These can be found in in many "security" bit sets for cordless drills, e.g. All Electronics CAT # BT-33. When I opened my dead charger, I found that the LM-7812 three terminal regulator had blown up. The other components were fine, so I removed the remains of the 7812 and soldered in a new one. That's all it took to fix it. All Electronics sells the 7812 regulator as CAT # 7812T for 50 cents each.

Gets pretty hot

Reviewer: from LAFAYETTE, CA US

This unit won't pull up a fully discharged battery. And it gets very hot in operation - enough to fill up the room with a plasticky smell. I'm afraid to let it run unattended.

Batteries are expensive, so it makes sense to use a decent charger if you can afford it. EDITORS NOTE: It sounds like you either overcharged the batteries or got the polarity backwards.

great concept - purch two and one died

Reviewer: from California

I know I could have returned this to AE - they have been good in the past.

These arrived with one damanged in shipping. I used these on small (7AH) lead acid batteries.

One worked for a while and then indicated that the batt was charged when it was not... never worked again (see other review on loose terminal). I think that with 7 AH batts one has to be more careful. Also - these were pulled from a computer UPS - when the battery is really flat - don't expect a trickle charger to pull it up.

Great concept - inexpensive trickle chargers. I should have just returned the thing once it stopped.

no reverse polarity protection

Reviewer: from Marietta GA

my 15 year old grandson demonstrated that this charger is not protected from reverse polarity connections. One second after he hooked it up incorrectly, it was dead. Other than that, I was pleased with it for maintaining my inventory of gel batteries.

Great for float-charging a Generator Battery

Reviewer: from Chicago

I have a large, electric-start backup generator with a U1-sized 24A-h battery in it. This used to run down when I didn't test-run my generator for half an hour a month to recharge it. Then, I had to jump-start it from my car. This was always unpleasant as the gen provides backup power during heavy thunderstorms or snow -- never fun times to be dragging around jumper cables. So I bought an expensive "Battery Tender" 6A max float charger (made for motorcycles) which eventually boiled my battery (!) though it was NOT supposed to. Finally, I bought this AE 500mA charger last year which has worked FLAWLESSLY at keeping my new 24A-h sealed lead acid battery safely topped off.
