i'd say charge it more, for a completely drained battery 2-3 hours should be good
You simply divide the MAH of your battery the MAH of your charger. For example my battery is 1500 MAH and my charger is 250 MAH. 1500/250=6 which means I have to charge my battery for six hours.
6-8 hours
when fully charged it can run upto 15 hrs...n its battery life is 2-3 years(as per my experience)...
This is a measure of battery capacity. It relates to how long a battery can produce a certain amount of current. For example, a fully charged 1500 mAh battery can provide 100mA for 15 hours (or 50 mA for 30 hours or 200 mA for 7.5 hours, etc.) The battery rating is the capacity for a new battery. After many charge/discharge cycles, you will start to see a reduced capacity.Related note: The capacity of a battery doesn't relate to the maximum current you can draw from the battery - that depends on several factors including the type of battery, its size and construction. For example you might be able to safely draw 15 Amps from a hobby style 1500 mAh Lipo (Lithium Polymer), but don't try to get 15 Amps out of 1500 mAh AA Nicads.
Blown fuse, broken socket, broken charger plug.
How many times you can charge an airsoft gun (in this case it should be AEG (Automatic Electric Gun)) depends on at least two factors: 1. The type of battery you use. Lithium Polymer (Li-Po) batteries have a longer life span than Ni-Cd or Ni-Mh. 2. Battery treatment. If you treat your battery/ies well (i.e. charge your Li-Po battery with a good balancer, not put it in a wet/damp environment, not dropping it) it can be charged hundreds of time without problems. Ni-Cd batteries have different kind of treatment. Read on manual how to treat your battery. My JG HK416 is still using standard battery (1500 mAh, 8.4 v, Ni-Cd) that comes with the unit. I've charged it at least 50 times and it's just never fail. I charges it with the standard charger unit after uses it for 2-3 small cqb games/skirmishes. I also upgraded my JG M4S-System with 1500 mAh, 11.1 v, 20c, Zippi Lightmax Li-Po battery with Firefox charger along with Turnigy balancer. I've charged it 30 times or so and it also never fail.
Is the battery fully charged? Try jump-starting it.
You should check the instructions for the answer. But an easy way of calculating the time needed is this super easy equation:Battery Capacity/Battery Charger Rate=Time to charge (in hours)For Example, a 1500 mAh Battery with a 250 mAh per hour charging rate will take 6 hours to fully charge.1500 mAh divide 250 mAh = 6 hrs.Or be the smarty pants and do it this way:the battery capacity x battery's mAh rating divided by the charger output (mA) x 1.4 (for NiCad batteries) = time (in hours).(1.5 for NiMh batteries)
1500 volt? I think not... and read the Mah output on the charger. Mah stands for milliamps per hour so if your battery is 1200 mah and your charger charges at 300 mah then you charge it for 4 hours. It's simple math. Honestly, spend the extra 25$ to buy a smart charger. It will be easier because they don't overheat, don't over charge your battery, tell you when they're done charging, and charge your batteries in about an hour or two
