Lightweight, very powerful. Started my small riding lawn mower with no issues.

Great value! Super light, about one-third the weight of a conventional battery. Used it on a lawn mower, no problem, and it turns better than regular batteries.

Will my bad boy rogue zero turn charge this battery when I'm using it I'm getting 32-34 V from the generator

A

Hi dear Clint, Thank you for your kind contact. The U1-M-480 lithium battery can be charged using your lawn mower charging system. For standalone charging,it is advisable to use a compatible charger (DC, Rated Charging Voltage: 14.60 volts), to the positive (+) and negative (-) terminals of the battery. Usually a lead acid battery charger is not available to charge a lithium battery,may affect performance, safety, or battery lifespan. Thank you for choosing our products. Best regards, Amy Aftersale service @TYKOOL Battery
