What to know before buying

  • The stated charging and discharging temperature range is a listing claim. Follow the battery maker's instructions for operation and charging.

Listing details to confirm

The title identifies the chemistry as LiFePO4, while the technical details describe it more generally as Lithium Ion. The supplied information does not clarify that terminology. Customer feedback mentions 800 cold-cranking amps, which conflicts with the title's 640CCA claim. Check the selected listing for the definitive chemistry and CCA specification. The listing also gives dimensions ending in 6.49"H in the details and 6.50" in a compatibility bullet. Confirm physical dimensions, terminal polarity and vehicle fit. It warns that some BMW battery-monitor systems may report faults or voltage alerts with lithium batteries, so confirm electrical compatibility before ordering. The listing advertises compatibility with several powersports and utility vehicle types, but this does not establish fit for every model. Match the size and left-positive/right-negative terminal orientation to your existing battery.

Customer feedback is favorable about battery quality, reduced weight and starting power, while fit experiences are mixed. These reports make the low listed weight relevant to buyers replacing a heavier battery, but the power comments cite 800 cold-cranking amps, conflicting with the title's 640CCA. Because fit reports vary, verify the listed dimensions and terminal polarity for your vehicle.

Positive themes

  • Customers describe the battery as good quality and lightweight, with some noting a reduction in carried weight.
  • Customer feedback praises starting power, though the stated CCA figure in those comments conflicts with the title.

Mixed feedback

  • Customer feedback on fit is mixed, with reports of both a good match and incompatibility.

Frequently asked questions

What battery chemistry is this?

The title calls it LiFePO4, while the technical details say Lithium Ion. The listing does not reconcile those descriptions, so confirm the chemistry with the seller before buying.

What is the advertised cold-cranking rating?

The title states 640CCA, but customer feedback mentions 800 cold-cranking amps. These figures conflict, so verify the exact rating for the selected listing.

Will it fit my vehicle?

The listing gives the YTX14AH-BS size and dimensions of 5.31"D x 3.54"W x 6.49"H, and claims left-positive/right-negative polarity. Compare both dimensions and terminal orientation with your existing battery and confirm vehicle-specific fit.

Is it suitable for a BMW with battery monitoring?

The listing warns that BMW LIN-bus monitors may show fault codes with LiFePO4 batteries and that older BMWs may show voltage alerts. Confirm compatibility with your bike before ordering.
