If you have a starter that spins but doesn't engage the engine and a battery that is always dead then I would look closer at the starter then the regulator. The regulator is part of the charging system but if the rectifier is bad then it might be possible for the battery to drain flowing backwards through the charging system but highly unlikely although possible. As for it to stop the starter from engaging the engine, that is not possible.
An auto motive can be recharged by connecting the dead battery to another vehicle with a charged battery by the use of a jumper cable by connecting both end to both batteries then starting the car with the charged battery inside.
replace it
they can be recharged by hooking jumper cables from a car to the mower or if the battery is fried you would have to buy a new battery for it Use a battery charger just like the one you use on an auto battery.
Yes can be charged
A torch (flashlight) battery is a dry cell, and is not designed to be recharged.
A battery that can be refilled with the energy it has. If it is in a phone, when you charge your phone, you are recharging the battery in your phone.
If it is an automobile battery then of course it can be recharged. It would we worthless as an auto battery if it was not rechargeable.
No because that means that the terminals have worn out and the battery leaked acid
The answer is no.
It has a rechargeable battery and can be used for a while then must be recharged.
Batteries are recharged with electrical energy.
because its out of gas
