Battery FEIN GBA 18 V 4.0 AH AS Lithium-Ion 4 Ah 600 g

The FEIN GBA 18 V 4.0 AH AS is a Lithium‑Ion rechargeable battery pack with a 4.0 Ah capacity and a weight of approximately 600 g. It includes a built‑in charge status indicator and Electronic Cell Protection (ECP), which protects the battery against overload, overheating and deep discharge. COOLPACK 1.0 technology reduces heat build‑up during use and charging, supporting longer service life. The battery is compatible with 18 V cordless tools that use the AMPShare or Bosch Professional 18 V battery interface.

Advantages

The battery offers stable power delivery and long runtime for demanding cordless tools while remaining relatively lightweight. The integrated charge status indicator provides clear information about remaining capacity. Electronic Cell Protection enhances safety by preventing overload, overheating and total discharge. COOLPACK 1.0 improves heat dissipation to extend battery lifetime compared with batteries without this technology. Compatibility with AMPShare and Bosch Professional 18 V interfaces allows flexible use across a wide range of 18 V tools.

Suitable for

• Professional and DIY 18 V power tools that accept AMPShare or Bosch Professional 18 V batteries
• Long continuous application requiring extended runtime
• Jobs where safe charging and protection from overload/overheating is required

How to use

Install the battery into a compatible 18 V tool or charger by aligning the battery pack with the tool’s battery interface until it locks into place. Check the charge status indicator before use to assess remaining capacity. Charge the battery with a compatible 18 V charger following the charger manufacturer’s instructions. Avoid exposing the battery to extreme temperatures and always store it in a cool, dry place when not in use. Follow FEIN and tool manufacturer guidelines for safe operation and maintenance.

Usage recommendations

For extended battery life, avoid repeated full discharges and store the battery partially charged if it will not be used for extended periods. Use only chargers recommended for FEIN 18 V batteries and allow adequate cooling between heavy, continuous workloads.
