Bosch Genuine BLUE 18v Cordless ProCORE Li-ion Battery 4ah

Suitable for use with all Bosch Professional (Blue) 18v Li-ion cordless power tools, ProCORE batteries offer the performance of a conventional battery in a compact and lightweight package.

Thanks to innovations including new-generation cells and Bosch CoolPack 2.0 technology, it is now possible to achieve more powerful performance from a very small package. The same advances increase energy efficiency and, by protecting against heat damage, extend the battery’s life. or repetitive tasks and overhead work, the Compact ProCORE18V 4.0ah option minimises fatigue and improves comfort. Its single-layer cell arrangement allows significant savings in weight and volume compared to a standard two-layer battery, but with no reduction in power.

The key to extending runtime and lifetime is intelligent heat management and design, as developed for Bosch CoolPack 2.0. This provides ideal conditions for efficient battery performance and prevents damage from overheating. Compared to batteries without CoolPack, ProCORE18V packs last 135% longer.

High-density polyethylene (HDPE) and thermoplastic elastomer (TPE) materials have been specially chosen to maximise the effectiveness of battery cooling elements. Their structure, which encases each cell, is designed to increase surface area, and thereby speed up heat dissipation. By avoiding gaps within the battery construction, internal storage of heat is avoided. The improved cell connectors used for CoolPack 2.0 also help, by lowering resistance and saving power.

A Single Cell Monitoring (SCM) system safely optimises power delivery from the cells, while battery status is clearly displayed by a new high-resolution indicator with five LEDs.
