This is the best battery ever. I have installed this battery in two of my generators, a 13KW DuraMax and a GenMax inverter 9KW and in both cases the electric starter starts every time, even if it's been 6mo since I started it, it still starts great. I never have use a battery tender anymore. These just keep a good charge for a very long time. It fits perfectly in the generator mounting space. I think it's actually smaller than the original lead acid battery. I simply use the built in charger from the generators. I haven't had any issues with charging at all. Fantastic battery for the price.

I have a Duromax XP9000 iH inverter generator with electric start and a sealed acid 12 volt battery. During the latest outage the battery failed eeven after being on a trickle charge. I was able to start it with a boost from Astro Ai S8 battery jumper I got on Amazon. Amazon also offerred the Weize Lithium 12 volt battery that would accommodate my generators need. It worked like a charm. The only issue I had was putting the smaller yet more powerful battery in the battery compartment in the generator. I was able to fix that as well.

Tried to contact seller with phone number listed with battery. Voicemail was full, they did text us back later that day and resolved our issue after a couple messages back and forth.

the battery looks great, a way better price, with a very tight fit. I was told by the AI assistant it is a direct replacement for the factory unit in a Yamaha Majesty 400. I did get it to fit, but the Yamaha Majesty compartment is a bit tight by 3/8 in, or 10 mm to squeeze than standard. I liked the added capacity so I removed the battery tray, and used foam from the battery box for a good fit. Not worried about leaks, as it is well sealed, with Lots more power capacity. Measure the thickness and decide if this is a good match for you, I don't mind a bit of fitting out for the added features.
