Blue Seas New Smart Charger
Keeping batteries fully charged is a science that cruisers have to master sooner or later. If today’s high-capacity AGM batteries aren’t managed properly, valuable amp hours in can permanently trickle away through sulfation, as we saw in our test of AGM batteries (See “Fighting Sulfation in AGMs,” PS May 2015). Good battery management means complete re-charging that matches the charging profile of your battery, and this means an accurate sensing of battery voltage. As we saw in our recent report on battery monitors (see “Best Battery Monitor Test Update,” PS October 2017) a good monitor will also keep track of temperature, as this can be a limiting factor in charge acceptance rate.
