Wouldn't start the generator for my pre-winter tune-up and testing. Sitting voltage is at 5.7 volts, much lower than usual (should be well over 9 volts or so minimum). I've pulled it and it's sitting on a charger right now, but I doubt I can trust this now for the winter, so I'll be buying a new one shortly. Generator works fine though (via a jump start), so that's a plus. Update April 2018: Living in New England, we got hammered during March with Nor'easter after Nor'easter. Lost power five different times, ranging from 8 hours to three days. This battery did its job well, starting the generator every time, first time. Although the battery gets charged when the generator is running, I also provide a trickle charge to the battery every Sunday for 8 hours (it's on a timer), and that probably helps also. I'll try to remember to update this review after a few more winters. Original Review: Bought this to replace the original battery on a Generac XG10000E generator. Old battery was 5 years old and no longer held a charge. Old battery also was 10 AH vs. the 18AH here, so I'm hoping it will do a lot of starts in cold weather without working out too hard. More AHs. Good. The location for this battery on the generator frame is tight, and the new battery slid into place perfectly. The battery comes with hardware for attaching the cables to the battery posts. As delivered, the battery voltage was 13.6 volts DC (unloaded). I left it on the charger overnight before using it to start the generator the next day. Worked just fine. Overall a good deal for a higher capacity battery that fits perfectly. Review: Excellent price--exact replacemnt. - Had to replace old battery in portable Generac Generator. It was easy to install and works just fine. The best price I could find locally was over $100.00, so this was a good buy! ## Features - ML18-12 SLA is a 12V 18AH Sealed Lead Acid (SLA) rechargeable maintenance free battery - UL Certified - Dimensions: 7.12 inches x 3.00 inches x 6.50 inches.
