Efficient Bosch cooling technology in and around the battery prevents heat damage, gives up to 65 percent longer run-time and up to 100 percent longer lifetime. 4.0Ah Cool Pack cells have finer 'windings' than 3.0Ah allowing more power density in the same pack size with less electrical resistance, making it more efficient.
This means less frequent battery charges and 4.0Ah batteries are fully charged in just 45 minutes.

2-year Bosch Battery Warranty
The Battery Premium Service is an extension of the scope of services (regarding validity period and content) of the existing 3 year warranty offer requiring registration of batteries with part and serial number and provision of sales receipt and registration certificate when batteries are sent in for service.
4.0 Ah Coolpacks have finer cell ‘windings’ than 3.0 Ah, allowing more power density (more ‘fuel’ (Ah) in same pack size) and less electrical resistance / greater ‘fuel efficiency’ (run-time per Ah).
