View Full Version : 600 mAh batteries??
I recently bought AAA rechargable batteries for my iAudio 5 but when I was buying I seen that there were AAA rechargable batteries that were 850mAh and others that were 600mAh.
My question is what is the difference between rechargable batteries that are 600mAh and 800mAh?
BTW I bought the 600mAh batteries.
200mAh! just kidding...
Anyway, the 800mAh batteries will last longer than the 600mAh ones because they have more storage capacity.
Anyway, you can get even better batteries (up to 1000mAh) here: http://www.thomas-distributing.com/aaa-nimh-batteries.php
You will notice a big difference in play time between 600 and 1000. The bigger the better.
Amperes is a measure of current, the amount of charge flowing past a point per unit of time. You can think of it just like current in a river. A milliamp (mA) is just one-thousandth of an amp. So then milliamp-hours (mAh) is the product of current times the unit of time, an hour, and the result is a measure of the amount of charge the battery holds. Usually coloumbs are used to measure charge, but batteries are designed to be discharged at a certain rate (very high discharge rates can lead lower than theoretical run-time based on mAh rating).
So basically, it's a measure of how much charge you can store on the battery.
Nice price for the AAAs (cheap shipping).
800mAh should offer 33% more runtime. Also, beware of anything not of a well-known brand like Sanyo (look for the HR (http://www.doddstech.com/~egdii/sanyocells.jpg) for Sanyo cells branded something else, like Duracell), Rayovac, Maha (some of which have been Sanyo), GP, etc., near or over 900mAh. Some good ones exist, but most are lying.
Also, it will help you get the most ot of the batteries, and keep the batteries in better condition, to get at least a "rapid" charger, rather than a timer-based one, and that charges one battery cell per channel.
Thanks for the replies.
I am charging the Energizer 600mAh Ni-MH batteries on my Uniross Ni-Cd and Ni-MH battery charger which just plugs into the wall. It doesn't have any timer system on it. I have to manually switch it off once charged.
How long should I charge my AAA rechargable batteries for if they are 600mAh?
BTW I see that Argos are selling Uniross 1000mAh AAA rechargable batteries. I might go for those as I go long cycle rides in the countryside with my iAudio 5.
Artmuzz, If I were you, I'd get a charger with at least LEDs on it that signify when charging is happening and when charging has completed. I can't imagine having to always keep track of the amount of time that the batteries have been in the charger.
