Thanks for the responses. I'll get the NOCO based on these replies.

They are all either useless or expensive. And the expensive ones will also be useless if you forget to keep it charged. Just maintain your car instead, and save the £80 or so.

Oh "just maintain your car" 

What a wonderful idea. 

What about what happened to me this week then where the car has been starting perfectly fine and then randomly out of the blue with no previous signs it was going to happen it just decided to not start?

Did you test your battery at regular intervals?

If you're referring to getting a multimeter on it or something every morning & night then no I didn't & I'd wager that 99% of people don't do that either.

I do however use something that goes in the 12v socket which also displays the voltage reading & this had been fine throughout yet this morning was mysteriously at 11.0v.

Nothing had been left turned on.

Something like this: https://www.amazon.co.uk/Topdon-AB101-Automotive-Professional-Alternator/dp/B083LN4V3P/ref=asc_df_B083LN4V3P will give much more useful information than just a voltmeter. Doesn't need to be twice a day readings, but its worth doing it once on your car battery then as we approach winter too, if its been a little while.

If you have the means of a permanent power connection to the car then a CTEK trickle charger is a good way of keeping your battery topped up if it isn't used for long periods. 

The cheaper ones won't charge a flat battery but they will maintain the charge.

Once a battery gets to 4-5 years old well worth having a battery check done just before winter.  Plenty of garages will do one free of charge and advise on battery health.  Last one I changed was due to a suspicion all was not well, a couple of lazy starts and sure enough it was towards end of life.  Having it changed saved an emergency call out at some point.

I get what you're saying. 

Just to state - the battery in question is branded & 3 years old, within its warranty.

Sometimes batteries suddenly fail.  I have had that happen to me twice now.  On both occasions, the car started OK, but something inside the battery broke, and it was (almost) dead.

Keep it simple.

There are loads to buy, £20-£200.

Two thing to know.

A lot of them will not work if the battery is flat as it does not read any voltage and thus will not fire up.

The more amps the better.

So must have a boost button to override the lack of voltage.

I love the GooLoo GT4000 unit I have. Prime deal £61.36 today.

Ordered my one on 8 March 2023.

The charge lasts up to 2 years, I drain it every November and recharge it just to make sure it will work when I need it.

Jumped a C4 diesel with a dead battery for a week, until the new battery was fitted.

Used at least 15 time to jump it on the same charge.

Also a mini petrol last month, Again over 10 times if not 20 times in 4 days on same charge.

I would give it 10/10

I haven't seen a car for a long time where the BMS won't turn off the interior light after (say) 20 minutes, to save the battery. Buy a jump pack if you want though.

Until something goes wrong, such as a actuator fails, or switch no longer makes contact.
