Normal battery output?

If it’s an intelligent charger I’d leave it doing its stuff overnight

Definitely! My car isn't my daily and stays connected to a CTEK intelligent charger whenever it's in the garage. When I bought my car I queried this aspect: BMW actually recommended it. The cars you see in the shiny BMW showrooms are all permanently connected to intelligent chargers.

Experience with other cars I've owned showed it can take up to 3 days for the battery to reach it's optimum level. They're very different to normal battery chargers.

Last car came with a newish AGM. Battery still going strong when I sold the car 6 years later. Leave it connected - does no harm.

Cars back on charge today...will keep an eye on it.

If the worst comes to the worst, a new battery is not ridiculous money so I will just bite the bullet. Just thought it best to try an intelligent charge first. Get it up to maximum charge and see how we go from there.
