Default on board charger question

If I install an on board charger on my boat can I leave it plugged in for long periods of time or do I plug it up the night before I take the boat out? Also do they have built in surge protection? And which is the best brand and model 2 bank charger? Thanks

Select a charger that is appropriate for the batteries.

This is the Lifeline Technical Manual. This is the best AGM manual available.

This reply shows the battery manufacturer's recommended charging current for flooded cell batteries and for AGM batteries.

The Charles 5000SP chargers are well-made. The one I installed on my boat has been a work horse for many years.

The construction has an aluminum bathtub extrusion for heat dissipation helping to ensure long-life.

Charles, ProMariner and Guest Marine chargers all get fairly high marks. If you get a good marine dual bank charger, set it for the proper type of batteries you have (Acid, AGM or Gel), you should be fine to leave it plugged in full time. Just don't get a cheap trickle charger or regular car automotive charger that may not have the proper charge and float/maintain profiles built into them.

Yup leave it powered all the time....the charger will only charge the batteries as long as it is specifically a marine charger as mentioned.....I use Guest brand charger with 0 issues.
