I've been doing some research about batteries and I've stumbled upon Rechargeable batteries that come in 2500 2700 and 2900 mAh. Obviously they are 1.2 volts and I am looking to use 4 of them to power the micocontroller at 4.8 but I was wondering if one was better than the other . . . After some NiMH research I came across these batteries at www.vapextech.co.uk (2900mAh) and was wondering if 2900 would be the best way to go.
Looking at standard Alkaline http://en.wikipedia.org/wiki/Battery_(electricity) I noticed they run nearly at 2900 mAh but I'm currently using 3 standard Alkaline (4.5V) so I was wondering if perhaps have 4 rechargable (4.8V) at 2900 mAh would cause any damage.
Thanks in advance!
