Given that the battery is working fine with no signs of issues then i'd leave it alone.

To make sure you're feeling safe I'd buy a good quality jump Start Batteyr pack device that would be insurance against a random failure of a battery. It'll get you going again with no need for external help or another car being about and you can take it with you to your next car. Insurance against a flat battery for life!

Topic starter
 

Eurocarparts have 365 day return policy. Buy a battery, stick it in the garage, if you don’t use it before April then just take it back.

I could carry it around in the boot with the right socket to replace it if it does I suppose.

If you’re going to put the old one in the mini, do you have a cut off on the terminal.

Disconnect the negative terminal every time I park it, partly for safety but also as a basic security feature. I also take the coil lead off.

You can all carry on about how to use jump leads now, by vote goes to earth to engine block or jumper terminal.

Good to know you’ve not had trouble after your battery change. The need for a recode does feel a little suspicious!

I would add here that I think the dealer recode probably does something, but I'm also pretty sure a smart battery management system should be able to recognise the change to a new battery without a dealer picking your pocket. Also, I replaced my battery with the exact same spec by the same manufacturer - I'd be more inclined to get a recode if I changed anything significant in the spec, such as AGM to flooded lead acid.

Replaced my van battery this March, it had been going for 14 years.

The new one is playing up already, had gone flat this week for no apparent reason.

It's been suggested to me that this is because the budget Lion battery is a POS, so I'm looking into the warranty terms now.

Better still get a battery booster and stick it in the glove box. Can be used for a number of things and are frankly brilliant.

What else do they do? And how much for a decent one?

You can get a higher spec battery, within reason (ones with really high amps tend to be very expensive anyway) it doesn't need to be exactly the same, as long as it's not less powerfull than stock, and will physically fit into your battery cradle.

Depends how many extra electricals you have... back in the day I was into silly sound systems with multiple amplifiers and speakers..it was quite standard to run a battery with much higher amps than standard spec so the sound system didn't trash the battery.

Just noticed something. The thread title says roulette but stick or twist is from blackjack.

I have 2 battery horror stories
1. An 05 plate passat, the battery died once down in the lakes and got it replaced at Kendal Halfords. The money that fitted it, cracked part of one of the drain vents and from then on used to leak water into the passenger footwell. Never got to the route cause, but ended up selling the car.
2. A 15 plate Zoe. For some weird reason, the 12v battery behaves as if it's connected to an alternator - only charges from the main traction battery while driving. There's a short somewhere which drains the battery over 10 days if the car isn't used. The error message reporting the failing 12v battery is quite alarming!

Well not a lot but they can have USB ports to charge stuff and possibly a torch also.

My old C-max used to kill batteries, they'd always die just outside the warrenty too!

Just get a jump starter. Doesn't even need to be a fancy lithium one, I've got a lead acid one, it's basically a motorbike battery with jump leads in a plastic box with a split charger (it charges via the cigaret lighter).

Hook it up, leave it for 5 minutes to put a bit of power into the cars battery and it gets you going. A lithium one would be a lot smaller and lighter though.

More rudimentary, I've got the c-max's last (nearly new) battery that I took out before it was scrapped. I'll probably take that with me when I go up North for a few months in the new year, just because I know at some point I'll do something daft like leave an interior light on after a night shift.

Almost forgot, and also to prevent your headlights dimming in time to the bass line hahaha :0

I wonder if some cars standard spec batteries are slightly lower spec than they ought to be, especially with newer cars having more equipment that requires electricity, and plus peripherals plugged into the aux/cig lighter socket, phones, tablets etc.
