It should.
It should.
The battery will recharge itself when placed in the ignition and the car is driven. I'm not sure how long it takes to completely recharge and I don't know if the battery is removable
About 3 hours, 1 hour is for an 80% battery charge
It depends why it doesn't work. If it is just flat, then usually you can. If the battery has been damaged then maybe not.
Yes...it will not have the same capacity afterwards. Yes. Everytime you run an auto battery down completely you shorten the life of the battery. It is not designed to be run flat as a deep cell battery is.
To calculate the time to recharge a 70Ah battery at 4 amps, you can use the formula: time (hours) = capacity (Ah) / charge current (A). In this case, it would take approximately 70Ah / 4A = 17.5 hours to fully recharge the battery, assuming 100% efficiency and that the battery is completely discharged. In reality, charging efficiency and battery condition may extend this time.
If it is only the alternator driven by the belt no damage will be done but your car battery will lose charge and not recharge. Hence a fast flat battery. Hope this helps.
When the battery looses it charge. It is designed to be run completely down before recharging.
recharge it or get a new battery
You would recharge the battery if it were not working
No, Nickle Metal Halide batteries are actually the friendly replacement for the Nickle Cadnium battery (Ni-Cad) that were prone to developing a memory if not completely discharged before recharging. Go ahead and recharge that battery when you need to and don't worry about memory developement, it wont happen with that battery type.
There is no such thing as resetting a battery. You can recharge it but not reset it.
You should only recharge it when the battery gets low.
