Brand new Fire Power Featherweight lithium battery in your choice of the two fitments above — pick the option that matches your bike's year before ordering, the two batteries are different sizes and are NOT interchangeable. Lithium iron polymer cell, a fraction of the weight of lead-acid, with a built-in battery capacity indicator. Read and follow the included user guide and safety instructions before installing or charging, and charge only with a lithium-compatible charger.
Yamaha changed the battery at 2023: 2022 and earlier electric-start YZ450F (from 2018) and YZ250F (from 2019) take the LFP02-B; 2023-2024 bikes take the smaller LFP03-B. If your bike is not on that list, message us before ordering and we will check your application.
