The correct way to charge a battery is to apply a charging current of around 1.5-2 amps to a maximum electrolyte specific gravity, then to fully discharge the battery at a very low 1 or 2 amps, then to re-charge the battery at a low amperage again, then discharge at a very low amps again. This process should be repeated until the electrolyte specific gravity ...

On older vehicles the alternator would give out a high rate until it became warm. This used to be known as its saturation point. The alternator output would then drop off to supply the demand put on it plus maybe a couple of amps. A later 'smart' alternator and its control system can carry out conductive tests while operating and will better re-charge the ...

If you are having issues where the starter is dragging or just plain not getting the car started, then I'd worry about it. I doubt your battery is sulfated. If it is having problems starting your vehicle, then get a new battery, not a new ...

Second - the other issues may or may not be related to the actuators. Can you answer this, do the intermittent problems happen only ...
