Airsoft AEG Battery Charge time: Ni-CD SC 1500mAh 7.2V?

Question

Anybody know how long it takes to charge one of these? It came with my airsoft gun, but it doesn't say how long to charge it.

Answer 1

on a site on hobbytron it says to charge for 4hrs and should not be over charged for 2-3hrs or it will ruin the battery.

Answer 2

To figure out how long to charge a battery for:

(battery capacity (battery's mAh rating)/charger output (mA - usually written on the charger)) x 1.4(for NiCad batteries, 1.5 for NiMh batteries) = time (in hours).

For example:

I have an 1100 mAh battery and a charger which outputs at 180mA. It's a NiMh battery so you multiply by 1.5.

(1100/180) x 1.5 = 9.146666 hours

Note that the result in decimal, so 9.16 hours is NOT 9 hours and 16 mins! 0.16 of an hour is approximately one sixth of an hour or ten mins.

Other things to note: The multiplier of 1.4 or 1.5 is to account for the resistance in the cells as you're charging, If you don't use it then you won't get a full charge.

Often online stores will tell you to change a battery for only a few hours. This is almost always wrong (they can't possibly know what combination of batteries and chargers you've got) they're covering their asses to prevent you from overcharging your battery on their advice and trying to claim for a new one...

Answer 3

divide 1500 by the number on the charger ,usually around 250 or 300, and then charge it that many hours only going over by an hour the first time and don't let it get hot.
