How can I approximate the charge time for a battery? I have a 9.6V 270mAH battery being charged on a trickle charger from a 12V 1A wall wart. And if was to measure the current draw from an amp, what would have to do to predict full charge battery length? And btw, the amp is a M^3ed PINT.

270mAh divided by the charging current being produced by the trickle charger.

That will give you a value of so many hours.

Example: If your trickle charger puts out 15mA of current then 270mAh/15mA = 18 hours.

Ok, I see now. Looks like I need to swap out a resistor to get the proper current for the trickle charge. Thanks!
