I have used this battery with an SEC America SF606 Heater Sentry inverter/charger to power a Toyotomi L73 Vented Kerosene Heater when the power goes out. It will operate the heater for over 11 hrs. The L73 is my primary heat so it can not be down during a power failure. The battery just does its job. Doesn't leak or smell. My battery is currently 3 yrs old with a projected life of 6. Expensive battery but worth it.

I first bought Optima batteries in June 2007 for my 2003 Peterbilt 387. At that time we were pulling a 53' enclosed auto transport trailer whose hydraulics were powered by a 12 volt DC pump. To save diesel, we had tried turning off the truck and operating the hydraulics from battery power, but even after only loading a couple cars, we'd have trouble starting the truck with the drained batteries. After replacing the OEM batteries with the Optima Group 31 batteries, we found we could unload and reload the entire trailer using battery power only and still have plenty of power to start the truck afterward.

My original Optima batteries have lasted over four years and 750,000 miles. I regularly drain them to virtually nothing when I park for the night and power everything in my truck (freezer, refrigerator, 1100 watt microwave, notebook computer, fan, radio and lights) without ever starting the truck or my generator to recharge the batteries. When it's time to hit the road again, the truck starts right up every time.

I have saved many thousands of dollars in fuel alone with these batteries over the years, and at the price listed here on Amazon, they are a real bargain.

I bought 4 of these from Amazon.com, and used them in a 300 watt solar-charged array to produce 24vdc, which was then coupled to a Chicago Electric pure sine wave inverter. After 2 yrs of very light duty service ONE of the batteries has FAILED! Amazon won't help you at all after 12 months - I'm talking with Optima directly...we'll see. My advice: Consider the risks; sure the price was great, the free shipping was cool too, but the after-sale service isn't exactly what I'd like.

Use the Optima Red Top for Starter Batteries in 4 different Vehicles - Really Long Life - No Issues - even at -40 Degrees F.

Use the Optima Yellow Tops for "Power Reserve" (House) Batteries in the RV - Deep Cycle - great Reserve power backup - can frugally go up to 4 days with out having to Recharge

Battery was destroyed at delivery. Sent back to Amazon. Don't buy it because UPS will destroyed the battery before delivery.
