Mighty Max Y50-N18L-A3 Battery.
Installed in a 1995 Yamaha XV1100 Virago. I'm the original owner of the motorcycle. It is meticulously maintained.
I Purchased and installed the battery in March 2024. The battery died in August 2025.
I charge the batteries on my vehicles with a battery tender once every 1 to 2 weeks, year round. I typically get 8 to 10 years out of my batteries. This battery lasted a year and a half under those conditions. Now it won't crank my bike over, and it failed a load test at 2 different locations that test batteries.
I realize it only came with a 1 year warranty, but under the conditions with which I maintain my batteries, it should have lasted much longer than a year and a half. It is obviously a defective battery.
I contacted Mighty Max and explained the situation to them. They refused to help me in any way. I will never buy another product from them.
