View Full Version : question about mAh

09-26-2007, 08:07 PM

I recently bought a charger for my AA rechargeable batteries for my camera, and my one set of batteries has a mAh of 2300. I have another set of batteries that are mAh 2650. The new charger I bought says that "your battery charger is designed to charge rechargeable batteries rated up to 2500 mAh". Am I able to charge the 2650's in there and if I do, will it just take longer to charge them than the recommended time, or can I really not charge them? Your help is greatly appreciated, as I need to know if I need to buy another set of batteries before my trip in two days. Thank you!!

They'll charge fine. It may take an extra 20 minutes or something but there won't be a problem

added opinion! i believe that 15 min chargers has a built in intellegent ic chip that detects whether a battery is fully charge or not! as in my case i bought a dynex 15 min charger and when i called dynex for support they said that the charger would cut off the charging process once it detected that the batteries had 2400mah even thou i was charging 2650mah! understand what im saying so basically i dont think it would work, but again it may depend on the charger?

its the same dilema im in right now! since i thought of buying some 2650mah duracells, but wasnt able to find any suitable chargers for it!

so i was wondering if the energizer 15 min charger which i am pretty sure could charge their new 2500 batt's would also be able to charge my new 2650mah duracells!

so that is the big question! nd i hope someone could answer that!

Personally, I would NOT use a 15 minute charger on any of themA 2600 mah batterie that is discharged to 50% will need 1300 mah in 15 minutes to fully charge. That is a charging rate of 5200 ma or 5.2 amps. That battery and charger are going to get very hot and going to seriously impact the total life expectancy of both. A 1 hour charge would not create nearly the heat load. And besides, AA NiMH cells are so cheap that I carry several sets of spares whenever I go out. I have even loaned AAs to people when theirs went dead and I still had several sets left fully charged. 4 to 8 hour charge will get the most juice into the battery and allow the battery to last the longest.

I use a 10-minute reconditioning charger.

I used to use a 1-hour charger from WalMart. That pretty well destroyed a lot of my batteries. I put them all through my 10-minute charger and most of them are now working well again.

may i ask what type or brand is your 10 minute reconditioner charger and where did you get it from?

I believe (without looking) that it could be digital concepts. I got it from the only pro shop in Columbia and that closed down in July.
