What does 12V - 4.5Ah means?

Recommended Posts

Hi Prateek,
Of course a rechargable battery should include time in its ratings. It is its capacity, or how long its charge will last for a certain load.

I think all batteries, especially disposable ones should state their A/hr rating. Instead of "super heavy duty", whatever that means. ;D

Can 6v 4.5AH be used inplace of 6v 10AH?
i had this battery in my samll car but it got damaged and i have only 6v 4.5 AH battery.Does it move wit h next battery
Obviously a 4.5Ah battery won't hold as much charge as a 10Ah battery.

The other issue could be maximum discharge current and charge current, if it has a built-in charger.
