Found this info on batteries so, I thought I would share it here.
How to charge your airsoft AEG batteries
Ni-CD Batteries - (Nickel-Cadmium) also pronounced (Nye-Cad)
Standard chargers:
1. You will need a charger that has a higher voltage output rating than the battery you plan to charge.
2. Most standard batteries are 8.4v, so anything higher will work.
3. mAH on the charger is the output of milliamp per hour. This is the amount of power that will flow into the battery given no resistance. This number does not have to be higher than the battery's mAH rating. The higher the rating on the charger, the faster it will charge the battery. However, not Ni-Cd batteries, you do not want to have an output higher than 2.5 times of the mAH capacity rating of the battery.
On a standard charger use the following:
X = Battery's mAH capacity rating. Y = Charger's mAH output.
( X / ( Y * 1.25 ) ) = Total charge time in hours.
On a pulse charger: Amp setting must not exceed 2.75 times of the mAH capacity rating.
Other battery info:
These batteries are infamous for developing a 'memory' so be sure to allow them to completely/fully charge on the first charge without interruption. After you have used the battery partially, you should discharge the battery with a discharger. This will help eliminate any 'memory' settings. If you battery develops a 'memory', it will act as if it has a full charge but it will not charge completely and you will lose energy which equals to playing time. Another way to say it, is that if it develops a memory, a full charged battery may only last 10 minutes.
Ni-MH Batteries - (Nickel-Metal Hydride)
Standard chargers:
1. You will need a charger that has a higher voltage output rating than the battery you plan to charge.
2. Most standard batteries are 8.4v; it is recommend that you use a 9.6v charger. Anything higher is not recommend.
3. mAH on the charger is the output of milliamp per hour. This is the amount of power that will flow into battery given no resistance. This number does not have to be higher than the battery's mAH rating. The higher the rating on the charger, the faster it will charge the battery. for Ni-MH batteries, you do not want to have an output higher than 2 times the mAH rating of the battery.
On a standard charger use the following:
X = Battery's mAH capacity rating. Y = Charger's mAH output. Z = Total charge time in hours
( X / ( Y * 1.5 ) ) = Z
Z * 4 = # charging intervals
Make sure to have a 5-10 minute cool-down time between charging intervals.
On a pulse charger: Amp setting must not exceed 2 times the mAH capacity rating.
Note: 1000mAH = 1 Amp.
Other battery info:
Ni-MH batteries do not have the memory problem like the Ni-CD; however, they are more heat sensitive. Charging Ni-MH batteries should be done in segments of 15 minutes intervals. If you have an automatic charger, be sure to read the instructions to make sure it is compatible with Ni-MH batteries. Not all chargers will charge a Ni-MH battery and some can even damage or destroy them.
* DO NOT OVER CHARGE YOUR BATTERY!! OVER CHARGING IS A FIRE HAZARD!!
NiCad (Nickel-Cadmium) - Good capacity, long life recharging, economic rechargable battery
NiMH (Nickel-Metal Hydride) - great capacity, long life recharging, slightly more expensive. This type of battery is quickly replacing nickel-cadmium type since it does not suffer from memory effect as nickel-cadmium does.
Lithium Polymer (The Rechargeable Lithium Battery) - Great Capacity, Very Expensive Battery and Combustible
