Battery Help
 

I recently aquired a Mini 8.4V 600mAh along with my new TM M4A1. The charger that i bought says "7.2 VOLT, 2-3 HOUR CHARGER" but under the output heading on the charger it says "Output:P DC 9V 700mA". So i decided that i would charge it based on the mAh, so 600(the battery)/700(the charger) * 60 (minutesin an hour) = 52 minutes. At first this appeared to work as the gun fired , but after 200 bb's (the ones that come with the gun) over a 24 hour period the gun failed to fire. the issue was the battery since i put my friend's battery in my AEG and it fired fine. What did i do wrong with the charging?!

If you read the Information section, there's several threads about batteries, their care, chargers, etc.
Try it.

See how the battery is 8.4V, and the charger is 7.2V? Charger's not delivering enough potential to charge the battery.

ok ill go have a better look around i guses, but could someone tell me how long or how mahny rounds a 8.4V mini battery is SUPPOSED to last?

Probably around 600-1000 in a stock gun.

We cant because it varies from gun to gun, charge rates, quality of the cells, type of cells, quality of the ammo, motor and electrical setup of the gun, etc.
