Generac Charger Needed

Hello. After having the battery die, I am looking to find at charger for a model XT8500EFI. I am not having luck so far. Also I understand there to be a port to plug in the charger with a 3 amp fuse in the area--don't see that either on the unit. Thanks!

On the front panel is a coax jack port for battery charging.
The 3A fuse is behind the front panel.

Generac OEM part # 10000020426 charger. Search part number for retail sellers.

Taken from owner manual. Port 5 is the battery charger input.....

For my rarely used machines I replaced the lead batteries with lithium. There are lithium batteries made specifically to replace lead batteries. All the special charging, balancing and safety circuitry is built into the battery so it is a simple battery swap. The longest I've tested was a battery that sat uncharged for a full year. It was still able to start the generator without trouble.

Just buy a lead gel charger and connect a quick plug pigtail to the battery. I did this on my Generac so I could see the battery charge condition. I purchased the Battery Tender brand.
The charger that came with the generator was just a cheap dumb charger.
