Frequently Asked Questions

Q: Does this battery come ready to install, or is there prep work required?

Q: Will this battery require ongoing maintenance after installation?
A: Yes. As a conventional flooded lead-acid battery, the BB10L-B2 may need periodic electrolyte refilling and charging over its service life. This is normal for this battery type and is noted by the manufacturer.

Q: What is the warranty on the BikeMaster BB10L-B2 Battery?
A: BikeMaster provides a one-year manufacturer's warranty on the BB10L-B2 battery (MPN 781065).

Q: I ride a 2005 Suzuki GS 500F — is this the right battery?
A: Based on available fitment data, the BikeMaster BB10L-B2 is listed as fitting the 2004–2006 Suzuki GS 500F, so a 2005 model falls within that range. However, we always recommend contacting our fitment team or checking your owner's manual to confirm the correct battery group size for your specific bike before ordering.
