Mighty Max Battery

Battery arrived quickly and we'll packaged. Never heard of the Mighty Max Battery Co. But have been happy with it since it showed up on my front porch. Perfect fit and fully powered to start my car. Saved money buying it this way instead of at the store and no core to deal with also more powerful than other store batteries. Very impressed with Mighty Max Batteries and would definitely recommend.

I bought the Mighty Max ML9-12 (12V 9Ah F2) battery to replace the worn-out one in my POWERVAR A3CEG251-11 UPS, and it worked flawlessly. Installation was simple — just matched the red and black terminals, slid it back into the UPS, and it powered up immediately with a solid green light. After charging for about 8 hours, I tested it by unplugging the UPS. My modem and Wi-Fi router stayed powered on for nearly an hour, and the UPS switched smoothly to battery mode with no interruptions. The build quality feels solid, and it fits perfectly in the original battery slot with the same F2 connectors. This Mighty Max battery runs cool, charges quickly, and provides even longer runtime than the stock 8Ah version. It’s also quiet and maintenance-free. For the price, you can’t beat it — reliable, easy to install, and perfect for keeping network or AV gear protected during outages. **Highly recommend this battery if you want to bring your UPS back to life — it works like brand new again

Bought from them directly on eBay and I’m very pleased with my product. They shipped fast and battery came well packaged. Better than expected. Cranked my royal star over in a heartbeat. Will replace my Suzuki battery with a mighty max when the original goes bad.

Nice and small lifesaver. Size is exactly as described. Battery was shipped extremely fast and packed well. Fully charged right from the box and ready for usage. I'm happy with this purchase. Thanks to the Mighty Max Battery!

Ordering from imperial industrial supply was super easy. The gentleman was extremely professional and very polite. I received my order from the East Coast, whereas I am on the West Coast, in three days. The battery is super solid and looking forward to having a rechargeable battery versus a battery which needs to be replaced periodically. I will definitely keep these guys in I order any equipment, especially for my generator.

Ordered a Mighty Max, model #ML22-12 battery to replace my internal battery in a JNC660 auto jump starter. Came in two days and was packed very well. It was the exact size to fit in the booster and the exactly the same power rating as the defective battery. Instead of replacing the whole jump starter, I was able to replace just the internal battery and have a booster that is as good as new.

Bought a battery for my Honda VTX 1800s. Big-box store reviews were good and couldn't beat the price. I put a tester on it when I received it and it showed "good" and "charged". Removed the old battery and replaced it with this and started right up. Happy now so we'll see how it holds up.
