going for a long drive is half of what u need, but essentially when the car is driving/running the alternator is pelting out all of this power = the battery heats up and 'thinks' it's full so it doesnt accept any more charge.
My lecturer at TAFE told me that the best way to keep you battery in top shape is to drive with your headlights on. Strange eh?
(He was an RAA call-out-person for 25+ years)
He put it to me as: The headlights being on takes the some of the current being produced by the alternator instead of it all going to the battery. So the same (nearly) as trickle-charging which is how a battery charger works. It charges the battery SLOWLY so the batt doesnt heat up excessively and think its 'full'.
Scenario,
1)flat batt, jump start, drive to Murray Bridge. Arrive. Switch car off. Try to start again, batt will be low or flat.
2)flat batt, jump start, drive to Murray Bridge, With headlights on. Arrive. Switch car off. Try to start again, engine starts.
## unless of course the battery id old and stuffed or faulty.
This is my long-ass-winded $0.02
