how large of batteries can it charge? would i even have to worry about too big of a battery?

I have it charging two deep cycle 6 volt battery's wired in series for 12 volts on my camper works great for that. I would think it will charge any 12 volt system, larger would just take longer.

It says "battery charges at maximum capacity for 500 recharge cycles." I just have mine sitting on a window sill, folded up, so it's charged in case of emergency. But I don't know how that affects its life. That's a lot of cycles...so I assume it will last a good long time since I don't need it often.

Don't do it! The excess voltage would surely burn something out. (If they even fit.) There are numerous suitable "double A" batteries that will work, including many rechargeable ones.

It would eventually charge it, I wouldn't leave it on any battery indefinitely though as it has no automatic mechanism that will prevent overcharge.

Yes as far I know you can. I have charged both batteries with it and have had no problems.

The pack will be too large unless it is ruffle the size of the original battery.but I do believe it will be too big.

I was able to charge my HP laptop without any issues. I am skeptical of the ~30K mAH capacity, however.

I am assuming not. It does take quite some time to charge batteries. That's not necessarily a bad thing though. If the batteries are charged too fast it can hurt their longevity and may not charge them to full capacity.

I use the 1 to 5 for charging hi-capacity batteries with no problems. It takes longer than charging just one, but that is to be expected. I'm not aware of any alternatives.

I would not since the charger senses your battery and goes to float when it reaches charged state so with 2 it may overcharge a battery, also this is a very low amp charging system so it would probably not do the job on 2 batteries.

Its absolutely perfect for this. I use mine for these things exactly. I dont know how many charges you will get, but it will be many as long as you keep the unit charged.

I get 2 and not quite a 3rd full charge. I feel like the size of this battery is overstated. I previously had a battery charger that claimed to have 11000mHa. and easily got four full charges out if it. I'm not happy with this current battery charger at all.

No problem at all. Just connect 2 or more 12v batteries in parallel. I use 4 x 12v batteries.

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

I have come to the conclusion that this works best at recharging batteries then anything else. I have 2 batteries that charge with this and it works fine. One battery is from the same company. I would think that any battery as long as it is compliant with the USB specs should charge fine.

It can charge 4 AAA/AA/C/D batteries at a time in any combination. It can also charge 2 9 volt batteries at a time I've used it with AAA/AA & C s with no problems.

no as long as its a 12v battery it will charge it, the bigger it is the longer it will take.
