INOX in new Jimny Lead-Acid Battery (JIS). It works!

Why do you need to check/charge the battery on a new car so often? Are you just doing lots of short stop start journeys and the battery isn't getting chance to charge up on a long run?

What a bout a battery tender then? Just keeps it on trickle charge and maintains the battery.

Is the battery not sealed? I've not checked, just assumed it would be. I'd be very surprised if the battery in a new car needs frequent charging. 90% of my journeys are a 2 mile trip to the station and back each day and I've never had a problem with battery drain, even on 10 year old cars in the depth of winter

Its been years since I have seen a battery that is not sealed for life (including my Gen 3 Jimnys), Therefore I took a quick look at the underbonnet photos of the Gen 4 I test drove and yes it has an old style battery. They really have taken the retro look to heart with this one!

Let us know how it goes.

I remember in The Olden Days motor factors sold tubes of "de-sulphation tablets" that never worked, but that was most likely because the problem wasn't sulphation, but shedding of active material and disintergration of the plates.

The internet consensus seems to be adding saturated epsom salt solution (magnesium sulphate) and trickle charging will remove existing sulphation, but I've not found the chemistry behind it. The best way to prevent sulphation is to keep the battery charged.
