I typically charge my NiMH AAs at 1C, so 2300mah = 2.3A, and they dont even get hot, only slightly warm to the touch...

well, there are 1 hour chargers made by raovac, energizer and etc...

So technically, you should be fine charging at 2.3 amps

I charge my sanyo 2300mahs at 1.5amps

thanks for the replies, it really helps!


marvi: I may steal them and use them in my RC car, in that case would it change your answer about cycling them?

Does anyone know if they make a 1.5 volt AA rechargable battery yet.....or are we still stuck with the way underpowered 1.2volt ones.........I'll take 12+volts of power in my radio anyday, over the 9.6volts you get with the 1.2 volt rechargeables, reguardless of how long they last.

there have been rechargable 1.5volt alkalines out for a few years now. Most major brands make them. I see them at Walmart and Canadian tire. Not sure why you would want them when 1.2v nihms do the job so well and last for ever

What do you use to solder the cells together? Does someone make battery bars for AA size cells?

Why wouldn't I want 1.2 volt cells..........We'll Joel....In "some" cases, the difference in overall voltage were talking about here...."can" make a difference in whether or not you get glitches or interference, especially if you race at tracks that have less than Ideal surroundings....I like to be as far away from interference as possible......not to mention that when I sent airtronics an e-mail concerning this some time ago......they replied that most highend radios (including theirs) were originally designed to perform best and most trouble free ,with 1.5volt cells.......I used to run 1.2volt rechargeables for a short time,but got tired of hearing the low voltage alarm beeping at 9.1 volts.....I'll have to check out some of the 1.5volt rechargeables you mentioned that they make............

Sounds good to me. I guess i have never had that problem. Been using my 3PJ for years and have never heard the low battery alarm. I have raced at various tracks both electric and nitro. The only place i could honestly say i had glitching that could not be explained was in Cleveland during practice that mystiriously went away the next day... I dont doubt the high end radios would need the extra juice. But if your running high capacity 1.2v cellls you should rarely hear the low bat signal...

But like is said above 1.5v rechargables are available in alkaline and nicad as someone just mentioned

guys I got a 4 AA battery thing, soldered some wires on there to connect to the charger and then charged them up.

My question is that the charge complete thing came up when there was only 178? mAh charged.

The other thing is that when charging the charger shows volts. it went up to 7.something(low 7's) but with 4 AA it is only a 4.8 volts pack. Maybe I am missing something. Charging at 1 amp it took 1:4?:?? is that about right?

i am leaving for most of the next week in 2 hours so if you ask a question and I dont reply until then its because I do not have computer access (grandmas house)

thanks for all your help so far, (and any future help)

Hey dude, are you sure your batteries were not already charged before you charged them, and that is the cause of the low numbers?

You can use a copper solder braid or solder wick. It comes in a small spool so you can cut to length. It is mainly used for "wicking" excess solder. You can find it a Radioshack or any electronics store. It is not expensive.

OK, thanks. I was looking for that stuff but couldn't find any. I'll try Radio Shack online. I've been wanting to make an extra TX pack!

they may have had some charge in them. Not enough for my digital camera to turn on through.
