In November 2011 I purchased two 90amp hour deep-cycle lead acid batteries to replace the my two elderly house batteries. Yesterday, 16 months later, One of the batteries is dead - bad cell confirmed with a load tester. I thought my batteries were living in battery-heaven as they are continuously maintained using an 85 Watt QPR solar panel and dual charge-controller. They have seldom been asked to do more than run my refrigerator for a few hours. I was told today that deep-cycle lead acid batteries will have a much longer life if they are "exercised" (discharged to say 50% capacity) every six months or so. Is this something I should be doing?
BTW: These are the batteries in question MARINE DEEP CYCLE DC27 90AH . This is the only vendor of marine batteries in St. Lucia and the waranty offered is minimal.
