Will this charger work on a completely dead battery? Can you use this as a power supply?

This charger will charge a dead battery provided the battery is not broken. I put a dead battery on the Schumacher for 30 minutes and then switch to my 'automatic' battery charger to finish the charging as it will stop when the battery is charged, but the Schumacher does not. I do not understand using the Schumacher as a power supply. It's a battery charger.

It's depends on the charger, not the battery. And, for this battery, never let it die, or it will die forever.

I don't know but I've learned if charger says bad battery & shuts off if you can put a little charge in with an older charger, this charger will then take over & gradually bring that battery back from the dead. my charger model is 12 v only and relatively low camps, but it has restored several batteries for me if given the time to work.

It is a very good charger, i us it on only one 12v battery currently, but i see no reason why it would not maintain the charge on your batteries as long as they are hooked as a 12v system, i am sure it would be more effective it you did one at a time and cycled them through

True, Like any rechargeable item charging it once it is completely dead will prolong the battery life to its fullest.

I actually used it to charge a dead battery. So if I understand the question, you can use it to maintain the battery or charge a dead one (it does take some time...12-24 hrs)

It is mainly used to "jump start" your battery, and not used as a "battery charger". Hope this answers your question..

Yes it will work! I've had mine for a few months now and it's held up really good. It does take a couple hours for a full battery though. That's really the only down side. Other than that it does charge the battery and it is very lightweight and transportable. (:

The battery charger is designed to charge the batteries and not to act as a power supply. I do have a new model just out that will milk olmost 4 gallons of milk.

It should work fine to charge the battery. You'll have to use an adapter. Once it's charged it'll go anywhere!

You should be able to charge these batteries, but get ready to learn you wasted money for crappy batteries... Most of the "high power" batteries I came across are fake and not holding more than half charge they promise. Only brand name batteries like Eneloop and Duracell were performed exactly as specified. Another problem with off brand batteries is self-discharge. I had several batteries losing up to 70% of charge within one month. On the bright side with this charger you will find-out what batteries you can trust. Good luck!

You can use the charger for an automotive battery, if all the battery connections and battery top is very clean. Recommend that the battery be disconnected from vehicle, so that the microprocessor is not reading the vehicle keep alive circuits! I have a negative ground battery disconnect switch to isolate battery from vehicle. Also, charger requires wall current type power source to function properly:)

Yes you could use it to charge batteries, though I would look for something cheaper that provides less power. This device supplies way more than you need.

Yes, it'll work but don't expect it to charge it all the way. Probably just a little emergency battery backup.

Nope. This might be a knock off styled battery charger, or the batter itself might be broke. Do you have any other batteries to try out to see if it's the charger itself or the battery? Someone you can borrow from? Do some testing to pin down what it is that isn't working here. Good luck.

Tyler, I tried to use this charger on a Helio battery. It would not charge it. I sent it back and got a refund. I'd be cautious about using this item!!!!!

Sorry, I just saw your question. I would NOT recommend this battery charger PERIOD. I ordered two of them and they are cheap and don't work.
