A110 Battery specs

[Miserablegit]

I believe it is an 027 size Stop Start battery
it's an EFB but I'd replace with an AGM


As I wait to see if there is a diy brake error reset I can do I took the battery out for a a drop test.
This was the result after being charged on an optimate for the past few days.



It says battery is good but needs recharging- my chargers are reporting battery full.

Does this look OK ? I was expecting better given it's kept on a trickle charger. Is this my problem causing the brake error?

Battery specs below - I hope they are of use to somebody as I couldn't find them anywhere else

Car starts no problem at all -
Fires immediately upon press of starter.

that is very good to hear

No, I kept the original battery as the fault was unrelated.
Just dont try some fancy lithium battery as there is/was a thread on RAOC saying the charging circuit won't work properly on a lithium battery.

The car has to be parked in an east-west direction before the battery removal in order to protect the polarity of the battery…

No, on a serious note, no special procedure other than the usual disconnect the negative post first.

I found I had to remove the front boot liner in order to get to the battery. I also left a door open to avoid any issues if I closed the bonnet by mistake.

You definitely will need to remove it. Perhaps consider fitting a trickle charge socket at the same time

I’ve finally taken the plunge and bought a new battery. Got nearly 5 years out of the old one but I normally get longer.

Bought a Bosch 027 AGM from Tayna with a 5 year warranty

It fits perfectly.

I can notice the extra power available in the electrical system - the hifi sounds more detailed with a more expansive soundstage and the engine really sings now ithe ECU is not being held back by the underperforming FIAMM option. (Oops sorry- meant to post in hifi thread)

I had to use my jump pack twice to start the car when I’d not left it on charge for a few days so took that as an indication that it was on its last legs. I don’t think the duff alternator last year helped at all.
