Can you use a 12v 5Ah battery to replace a 12v 4Ah battery?

As the dimensions of the 12 Volt 5Ah battery and the 12 Volt 4Ah battery are exactly the same, they are interchangeable. Amp-Hours basically show how much energy a battery holds. As long as the battery you want to replace has the same voltage and dimensions it is okay to substitute it with a different Ah replacement.

What does 12v 4Ah mean?

The letters “Ah” or “AH”(“amp-hour” or “ampere-hour”) that you see on your battery essentially denote the charge capacity. The number alongside the letters will tell you the total amount of current the battery will consistently deliver to your tool over the course of an hour.

4 Ah / 20 Hour Rate = 0.2 Amp Device If we connected this 4 Ah battery to a 0.4 Amp device (twice the drain of a 0.2 amp device in the example above) it would actually last around nine hours, not ten as might be expected.
