when fully charged it can run upto 15 hrs...n its battery life is 2-3 years(as per my experience)...
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.
If they're the same voltage and chemistry - yes
1.5 Amperes, or Amps.
A 7.2V battery. I cannot remember the mAh. I think it's somewhere around 1000-1500 mAh
6-8 hours
8.4v 1500 mAh
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)
It would just last longer between charges.
A nickel caddmium (Ni-Cd) battery. It's an 8.4 volt 1500 mill amps per hour (maH)
Not a good idea. It will work but not as long as the 1000 mAh battery.
9.6V Nun-Chuck 24000 Mah battery
No reason why not. So long as the physical size of the battery matches, and the voltage it delivers is the same - you should be able to replace it with the higher mAh battery.
