[QUOTE="chrisc, post: 915622, member: 746"] You cannot run down lead-acid, whether flooded or gel, to 50% depth of discharge. Run a 12 volt battery a few times under 11 volts, and the recovery is compromised. I have had customers who did this and now they find when they have no AC power after dark, their inverters or UPS batteries let them down. Instead of getting a couple of hours, they get 20 mins or less On the other hand, if a flooded or gel battery is properly managed, it will give 6 to 10 years of life. I've seen the brand "Power Sonic", made in the USA, last for 15 years If you want a fit and forget battery, it is a lithium-ion Expensive to begin with, and it needs a well set up battery management system, but a) it will last, b) supplies all the power you need and c) is a fraction of the size and weight of a lead-acid battery If lithium ion is good enough for Tesla and most other electric cars, its good enough for me [/QUOTE]
