AGM: how it works

Nothing sloshes around in a glass-mat battery, because every drop of acid is held in the separators. Leisure vehicles choose AGM when the battery lives under a seat. A battery tester gives a clearer picture of AGM health than a voltmeter.

Common questions about the MK Battery ES9-4

How should I charge a battery like this?

Look at the sticker on the battery you have now. If it also says AGM, this is a like-for-like choice. If not, check your vehicle or system can handle the change.

Are there other sizes in the same series?

It belongs to MK AGM. If you need a different size with the same construction, look within that range.

Will the MK Battery ES9-4 replace my old battery?

Hold your old label up to ES9-4. Same code plus same size and terminal side means a direct swap.
