This may seem a pretty basic question but I`m after some AA rechargables batteries but I`m not sure what the mAH rating means, I assume that the greater the number the longer they last, is this correct? :help:

Kind of, however different rechargeables can be made with different technology. The current favourites seem to be Sanyo Eneloops or Uniross Hybrio

I use Eneloops and can highly recommend them:thumbs:

TO answere your question
mAH is the amount of charge it holds
mAH = MilliAmp Hour
if you have say 1000mAH and you have draw 100 mAmp per hour it will ast for 10 hours same if you draw 10mAmp per hour it will last for 100 hours.
so the bigger the number the longer it will last on a charge

Not 100% true if in use all the time it will be the same for ANY type of battery with the same AH it has the only thing that might be different is any not in use discharge it might have
 
You can get batteries that are rated at around 2500mAh, for a reasonable cost( Maplin have some at £8.00 for 4) Don't forget you'll need a suitable charger.
 
Chaz is absolutely right with his explanation. But personally I find eneloops a reasonable compromise. They certainly don't have the highest capacity but do tend to hang on to the charge longer than most. I've moved totally over to these.
 
I use Eneloops and GP Recko. Both are great and there is a gnats prick between them for performance. LSD (Low Self Discharge) batteries are definitely the way to go nowadays.

Prior to switching to Eneloops I used Fujicell 2700mAh rechargeables, which can be found on Ebay/around the web for about a quid each if bought in decent quantities. I've found he Eneloops, although they have a lower rating to be just as good, but with the added bonus of retaining a charge for a lot longer when in storage.
