a lot of digital cameras that use li ion (rechargeable) battery don't have a very high mah around 1000mah or so although they have a high voltage. will a couple of 2a or 3a battery have the same effect. 3 AA or AAA batteries together have a 3.6v. 1 AA battery have around 2600mah and AAA have 1000mah. so actually one of them already have the same mah as the li ion battery I am not sure if this answers your question, but Dan has some interesting things to say about li-ion batteries that you may want to know. |
