Jimny Battery

Hi all new to the forum and finally a Jimny owner! Which will be my daily drive plus some offroading when the chance arises. I have question about the battery, Ill be changing it within next week or so before the cold weather comes in as its old. Can anyone reconmend a batterry to upgrade too? Ill also be potentially adding extra lights at somepoint.

I kept with Yuasa and went for the YBX5057. 5 year warranty. Luckily Halfords had it in stock.

You need one that the alternator can fully charge. Buying a huge capacity battery and a standard alternator does not work as the alternator can never fully charge it.

I don't think bigger batteries need higher charging voltage. Jimny should be able to charge even 200Ah battery without issues, just slower.

I think so too. Also depends on how much you draw from it, temperature, quality of the battery and so on.

Our VW T5 is driven around locally most of the time seldom gets more than 3-5 minutes of use as most things are close by. In winter sometimes we use the Webasto to heat the car first, seat warmers, allways drive with lights on, heated mirrors and rear window all just for the five minutes of charging.
This of course leads to short battery life until couple of years ago i bought an AGM battery.
So pleased with it, no problems anymore.

Many cheap batteries nowadays does not cope with our cold weather either (Norway).

I'd be inclined to agree with Jim; Stick to an original particularly with a 5 year warranty in the offing!

In the past I've usually fitted an "extra-heavy-duty battery for a diesel" in every car I've had, diesel or not! I've never had a problem with batts not fully charging and I don't travel very far. But whatever you do, like Yakuza says - don't buy cheap!
In winter my car is mostly used only in the dark (go to work, return from work) and I allow the engine to warm a little without lights; fans; wipers; etc before moving off, while I check my phone messages/make calls, put on seat-belt. and don hat and gloves, I've never had a problem with a heavier duty battery not fully charging.

I notice now the cold weather has started that my engine takes quite a few more revolutions on the starter before it lights up. Last winter was the same, but throughout summer it was fine, so I might consider another battery myself soon.

Halfords is a good place to go if you have, or know someone with, a Trade card
