Well done order…

I almost threw out my 20 year old portable battery jumper because of old recharging battery won’t recharge. I found this replacement battery from Raion by chance on internet that was compatible to my old Diehard 750 portable charger, it was delivered in a timely matter. I installed the new battery and it’s charging up like it suppose to. A new average price portable charger $100. Replacement battery from Raion not expensive. Thanks!

The product came in a timely manner and the batter worked great. A little note with it saying if it was charged or the best way to take care of the batter would have been helpful!
