That's the sort of job an Optimate 2 was designed for (as it can be
left on indefinitely). ;-)


Thanks - it is a LA sealed battery, and I've got one of those Lidl
'intelligent' chargers, which I'd guess is quite gentle.

Well, ours has two rates (indicated by the symbol of a car or a
motorbike) and so yes, the motorcyle setting could be considered
better for that capacity / design of battery.

Yours could state on it the rate(s)?
