Replacement Battery

TheBody

Hi all.

Went out the start my car this morning and the battery was just about able to turn the engine but not start it. The battery is around 8 years old, so it owes me nothing.

The car is a 2013, 1.6L diesel Ford Focus. If I was to try and replace the battery myself, will I have problems with the start/stop on the car or any other onboard computer stuff? Would I be better of just getting Halfords or local garage to do it for me?

Thanks for any advice you have to offer.

You can replace the battery yourself, no rocket science. Only thing what you can not to do yourself is the programming. Yes the car can learn the new battery itself but mean time it can cook the new battery, what reduce the battery expected life time. The manufactures did not made the joke when they installed that databit to the computer. Now comes big, nasty, smelly, ugly guys who said they replaced this week 100 batteries and never programmed.... Classic cars, go ahead there is no computers. Modern cars, DIY and get programmed.

I've noticed this on a few of your posts. You've an awful chip on your shoulder regarding people disagreeing with you even before anyone has even disagreed with you. It's off-putting. Who wants to contribute to a thread with an angry guy dishing out insults to imaginary adversaries?

I’ve noticed you noticing, and it pisses me off. Will nobody think if the big, nasty, smelly, ugly guys?

Yeah. His threads are unnecessarily chippy.

You can change the battery yourself, its a very simple process, main thing to keep note of is the information written on the old battery, make sure the new battery matches up i.e CCA number, Ah, also the battery number itself, a three digit number that will need to be matched up, say your old battery is 110, you're new battery will need to also be 110. All of this this especially important with AGM batteries which are commonly used in start/stop systems.

On the programming, you can start and drive the car. Yes it may cause your battery lifespan to be reduced, you could install it yourself and ring your local garage or dealer to code it for you, takes 2 minutes to do with a good scan tool.

Thanks all.

In the end, I went to Halfords. They put some device on the battery and said the battery and alternator is fine.

I went straight from there to a garage in the town who similarly put some tester on the battery and said it’s goosed. They changed it there and then and the car is fine since. €196 for the battery and fitting.
