Some solar controllers start each new day at a new absorption voltage charging cycle.

Use temperature compensated charging for all charging sources.

Not all chargers that claim to be smart are in fact smart. Odyssey TPPL AGMs prefer 40 percent of amp-hour capacity as minimum charge current.

Size your most powerful charge source, usually an alternator or inverter-charger, for a minimum of 20 percent of bank capacity.

Don’t regularly discharge your bank below 50 percent state of charge.

Get back to at least 80-85 percent state of charge (full capacity) with each charge cycle and get to 100 percent state of charge as soon as you can thereafter.

Charge to full as often as possible, this point cannot be over emphasized.

Here are some tips that came out of our test that can help you prolong the life of your AGM battery. Even after just thirty of these cycles, some of the new absorbed glass batteries in our test never fully recovered to their pre-test capacity. For the more recent test of partially charged AGM batteries, Rod Collins of Compass Marine and cycled five different batteries through 30 deep cycles (to below just 50 percent state of charge) and then put them on the charger for one hour to demonstrate just how quickly a cruising sailor can ruin a good battery.

In 2015, we carried out a comprehensive update of our 2006 test of sealed valve-regulated lead acid batteries also known as either gel or absorbed glass mat batteries.

This isn’t the battery’s fault it is just a lack of understanding of how to properly care for an AGM battery. This typical battery use, or abuse, is called partial state of charge operation, and if it continues, a sailor can see his AGM battery perform noticeably worse than a less costly, deep-cycle flooded battery bank.

In reality, few cruising boats (or any boats kept on a mooring) return their batteries to 100-percent state of charge after each cycle. There are many things that can lead to reduced battery capacity in an AGM battery, but most often the cause is due to poor maintenance and charging regimen.īattery manufacturers want their batteries recharged to 100-percent state of charge after each discharge. By now, many sailors have enjoyed their first long weekend on the boat this year, and some may have noticed that the expensive absorbed glass mat (AGM) battery they bought last season or the year before isn’t holding a charge like it did when new.
