Users with listed Bosch models

Owners of the Bosch models listed above will find a direct fit that supports normal charging cycles and consistent output. Buyers whose equipment uses a different battery form factor or voltage should look elsewhere, as this pack only suits the named part numbers. It does not serve tools that require a higher-capacity pack or a different connector layout.
