Nissan Primera P12 1.8 battery replacement

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Nearly replaced my battery today as my gf had left interior light on overnight. The breakdown dude charged it, took a reading and says, "its only 70 mate - should be 470AH. This battery's scrap". Well after a one mile trip to halfords, the tech took a reading of 200 and says "if its gone up that much after 5 minutes driving, try it tomorrow morning after a few miles driving". Which I will, but is a regular multimeter up to the job?Thanks to halfords for taking the time to give advice, did not expect to leave the place having spent £0... but has he got a point? His meter decided all cells were ok. Cos £100 battery change is no fun, I blew £200 on a new exhaust Friday so I'm done with spending for a bit!
I heard removing primera battery messes withe the ecu, is it a big deal?

	For a small sum, I bought a battery tester for my P12. I can therefore: get more information than my multimeter provides check the battery regularly without having to visit a garage know whether the battery is towards the end of its life and - if it is - replace it before there's a breakdown. You might find a battery tester handy, too.

	well there's sure some bs about - no issues with removing the battery. And for some 2021 advice, you can get a new battery £53 at independent places, rather than £94 at halfords. My multimeter tests up to 10A, I'm not sure how to measure current-holding of the battery without it burning out. Would I take a reading with the ignition off?
