[QUOTE="johnb2713, post: 547152, member: 35153"] The EVE cells I've used in my batteries (and the Fogstar ones mentioned) have a predicted life of 6000 cycles, a cycle is fully charged and discharged. Assuming one full cycle per day, that's 16.4 years. A couple of points, the batteries don't fully cycle every day so that 16 plus years is longer and when they're deemed end of life is when their capacity drops to 80%. Even at end of life they're still providing worthwhile storage eg 20kWh would be down to 16 kWh. [/QUOTE]
