YTX9-BS GEL Battery Replaces Honda TRX400EX FourTrax Sportrax 99-13

Easy install, fit perfect.

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.

Great Batteries, arrived fast and super easy to install.

Performance excellent for my Predator 9500 generator

When I need to replace me batteries in my many backup UPS this is the brand I have been using. They are reliable and reasonably priced compared to other brands. I highly recommend them! My wife is a photographer and have a dedicated UPS for each NAS, having a reliable UPS to manage brownout and power outages in crucial to keeping your electronics working.

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

I ordered a Mighty Max ML8-12 8 AH battery from Amazon to use with my game trail camera. It was delivered fully charged and ready for use. I placed it in the battery pack box, connected the terminals, plugged in the charger and camera and everything was working!

Working great on our hot wire

I had ordered my Might Max AGM H6 GROUP 48 12V 70AH 760 CC 120 RC car battery on Amazon and received it two days later. This AGM battery has saved me from trying to diagnose the problems of why my car want start, and why so many different problem codes are popping up on my OBD2 Port scanner. So, if your car battery is more than 5 years old which is recommended to be charged and replaced in 5 years with a new car battery, try the Mighty Max AGM battery that has a longer than 5 years life span.

It was nice to be able to get a battery replacement. The company has discontinued the product and no longer sells the battery. The generator is only seven years old, but being able to get the battery through Amazon was great even though it was an inch too tall, we’re gonna make it work.
