hi guys,

i would like to build a charger that would best fit my batteries
(AA 1.2V,2700mAh)

what specifications are better?

fast or slow(high or low current)?
best charging time?
constant or trickle?

do you have any circuit or site where i can find a circuit to use for my project?

thanks alot in advance...

 

NiMH prefer a fast charge with either Delta V or Delta T (or both) sensing for end of charge.

 

Have a look at BQ charger ICs datasheets and application notes (now owned by TI).

 

Here is a link to a very good reference on the do's and dont's of battery charging. Battery University
