Review on Renogy 12V 100Ah AGM Battery: High-Performance, Low Self-Discharge, And Safe For All Your Off-Grid Needs! by Jae Newton

Purchased two of these to replace the old batteries in my two backup sump pump systems. The old batteries started failing and leaked acid which made a huge mess. Had then for two months. So far so good. Purchased these because I wanted a sealed gel battery that's maintenance-free and something that'd last a long time. I've had V-MaxTank batteries in the past but they've quickly become cost-prohibitive for my application costing over $300 each. These Renogy batteries seem to be quality made. Time will tell how long they actually last.
