This is a 8.4v Nimh 1600mah Airsoft Battery with a mini Tamiya (Marui) connector. WARNING: Do not overcharge batteries! If they overheat, you could cause damage to the battery, and create a potential fire hazard! You should calculate the proper amount of time required to charge a battery by dividing the battery's milliamp capacity by the chargers charge rate, e.g. it would take a 500 mah rate charger ~ 3 hours 15 minutes to charge a completely drained 1600 mah battery. If you are not certain of a battery's remaining charge and you wish to charge it, place the battery on the charger and check it every 5-10 minutes. If the battery is warm to the touch, assume it is fully charged.
