removing battery for external charge

[Mandrake]

I accept that I could be wrong re acidity changes. What I was told was that as the charge dropped, the acidity level increased, and, over time, this would rot the plates. However, as I said, I could be wrong (possibly by being given incorrect information).

Nope, it's definately strong acid when charged, weak acid when discharged:

A dead flat lead acid battery that hasn't been left flat too long (maybe a few hours) is still difficult to charge due to the very high resistance of the weak acid mix but it will recover given a chance. When its left too long the lead sulphate on the plates causes a permanent high resistance which prevents the cell conducting properly. "Sulphated plates".

I take mine out and use a decent trickle charger. I have an Optimate for my motorcycle so I use that.

If that can't recover a battery nothing will.

It has a test and discharge cycle. If I try to recover a 60Ah battery, they reckon on 1 hour per Ah.

The charge automatically adjusts and increases as the battery is able to accept more charge.

Nice piece of kit.

I heard GSF were doing good offers on Bosch S4 and S5 batteries a while ago.

I stand corrected, and thank you for giving me the right information.

PS, Mandrake, I am glad to see that you are managing to get your V6 healthier. Keep going, you will get her right.

I haven't touched the booster, not even sure where that is!

Sorry pal booster was just garage slang for jump starter.
