Angus76 Posted October 17, 2021 Report Share Posted October 17, 2021 (edited) Hi, I’ve not driven the car for a few days and the battery is not turning the engine. I can unlock etc. Multi meter shows 11.53v so I think it’s life is over! Could anyone recommend a replacement battery? I dont think there’s a special procedure is there in changing it? Other than windows up and down afterwards? And drive for steering angle sensor etc.. Will the alarm go off? Thanks very much 👍 Edited October 17, 2021 by Angus76 Quote Link to comment Share on other sites More sharing options...
818 Posted October 17, 2021 Report Share Posted October 17, 2021 (edited) Ours was in the same boat, I fitted this one yesterday, no issues, psm failure light went away after about 20 feet driving. I don’t know what price it reads without being signed in but it was £93.50 with a trade card https://www.halfords.com/motoring/batteries/car-batteries/yuasa-hsb110-silver-12v-car-battery-5-year-guarantee-281464.html Edited October 17, 2021 by 818 Quote Link to comment Share on other sites More sharing options...

Turn the ignition on (don't start the engine), and off, but don't remove the key. This will stop the alarm going off when you disconnect the old battery. Negative lead off first, then positive. When the new battery's in positive on first, then negative. 1 Quote Link to comment Share on other sites More sharing options...

Angus76 Posted October 17, 2021 Author Report Share Posted October 17, 2021 Thanks very much for the replies. Am I best going for an 800Amps (CCA) and nothing less? If I remember correctly the car currently has a 640. Quote Link to comment Share on other sites More sharing options...

If I remember correctly the car currently has a 640. 640a is too small for a 6 cyl lump imo, I wanted maximum cranking power for cold weather so fitted that 85ah 800A one above, it’s quite a bit longer than the one that came out but easily fits Edited October 17, 2021 by 818 1 Quote Link to comment Share on other sites More sharing options...

2001pt Posted October 17, 2021 Report Share Posted October 17, 2021 Highly recommend this one which is what I went for. Both Tanya & Exide have a good reputation on here https://www.tayna.co.uk/car-batteries/exide/ea722/ Quote Link to comment Share on other sites More sharing options...
K.I.T.T. Posted October 17, 2021 Report Share Posted October 17, 2021 Just buy a 096 / 110 fitment with the best specs that suit your budget from Bosch / Varta / Yuasa / Exide. You can't really go wrong. Quote Link to comment Share on other sites More sharing options...

It needs to be tested under high current load. The voltage difference between the battery no load and with everything switched on - main beam, heater etc, may give a better clue. But charge the battery first. If the car then starts, take it to a battery specialist and ask them to test it using specialist equipment.

Well... I got Halfords to price match Tayna so £40 off! My current battery has what looks like a drain straw poking out of it. I don’t think the Yuasa one does? I can see a red bung to the right hand side. Quote Link to comment Share on other sites More sharing options...

Absolutely, I’m going to do a load test etc. to check the alternator etc. I think the previous battery was perhaps a bit weedy for the job anyway. 👍 Quote Link to comment Share on other sites More sharing options...

It should have plastic tube connected to it, and run to the outside, clear of bodywork. Quote Link to comment Share on other sites More sharing options...

This is what the new battery has in the same place. But no tube protruding. Quote Link to comment Share on other sites More sharing options...
iborguk Posted October 18, 2021 Report Share Posted October 18, 2021 Yes swap the vent plug/elbow from the old battery and plug it into the tube. Removes potentially harmful hydrogen gas from the frunk. Quote Link to comment Share on other sites More sharing options...

Standard battery for that is a 70 amp hour with 630 CCA. A larger battery than needed is simply adding weight and costs. I'd go for the maker's one recommended for your model. To get best battery life, just make sure it doesn't get heavily discharged. As can happen on a little used car, if you don't use an external charger. A larger battery may, of course, give you few more days before this happens. But if being left unused for more than 3 weeks or so either disconnect the battery or use an external charger.

Does the old battery vent pipe elbow fit the black hole shown on the top left handsome shown in this photo ? https://www.halfords.com/motoring/batteries/car-batteries/yuasa-hsb110-silver-12v-car-battery-5-year-guarantee-281464.html Edited October 18, 2021 by iborguk Quote Link to comment Share on other sites More sharing options...

Left hand side (negative) had a hole. So I’ve plugged in the vent elbow to the left. Right hand side has a red plug that’s very firmly in place. Am I ok to leave it in. Surely just one vent required?
