Bosch 18 Volt Lithium-Ion Battery Pack 4.0 Ah delivers 18V power in a compact pack, so cordless Bosch tools can stay lighter while still handling everyday drilling, driving, and cut-off work across a jobsite or shop. The 4.0 Ah rating provides extended runtime between charges, which reduces downtime walking back to a charger during repetitive tasks. This battery is a compact pack, so it balances weight and capacity for all-day use where maneuverability and fatigue matter. As a lithium-ion design, it maintains usable power across most of the discharge range, helping tools run consistently instead of fading early under load. The battery belongs to the Bosch line of woodworking and power tool batteries, so it fits into a professional cordless workflow where multiple tools can share the same voltage platform. Each key design detail focuses on keeping the battery working longer between replacements in normal tool use.
This 18V CORE compact battery is designed as a pack for Bosch cordless tools, so swapping it on and off tools follows the same slide-on battery interface already familiar to Bosch users. The compact format supports quick changes in tight areas, because the smaller pack footprint allows easier access around handles and housings. The 4.0 Ah capacity means fewer changeouts on medium-duty workdays, simplifying battery rotation planning in the shop. The integrated fuel gauge lets users check charge level before climbing a ladder or moving to a remote area, which supports smoother sequencing of drilling, fastening, or cutting tasks. Because the housing is durable and withstands a 3 m drop, users can handle multiple changeouts on trucks or scaffolding with less concern about routine bumps turning into downtime.
The 18V CORE compact battery, identified as GBA18V40, fits into Bosch 18V lithium-ion applications where a balance of runtime and lighter weight helps productivity. Woodworking shops using cordless drills, drivers, and saws benefit from the 4.0 Ah capacity, which supports longer operation between charges on repetitive cabinet assembly, hardware installation, or panel fitting. On construction or installation sites, the cold weather operation down to -4 F keeps cordless tools working in unheated buildings or outdoor conditions, so crews can continue drilling and fastening when temperatures drop. The advanced heat conductive housing manages internal temperature during extended use, which suits tasks that keep tools running for longer stretches, such as driving fasteners into framing or assembling shop fixtures. The compact pack format helps in confined spaces, so users can maneuver tools inside cabinets or under counters without a bulky battery getting in the way.
The unique Cool br Pack Design with its advanced heat conductive housing pulls heat away from battery cells, which supports up to 2x longer life, so users can plan on a stable fleet of batteries instead of frequent replacements. Longer life at the pack level reduces interruptions from sudden failures during high-use periods. The integrated fuel gauge shows charge status at a glance, so crews can stage charged packs near active work areas and keep tools turning instead of guessing on remaining runtime. Cold weather operation down to -4 F gives this battery flexibility for seasonal work, because installers and builders can keep the same Bosch 18V system active from warm interiors to colder exterior punch lists. The durable housing that survives a 3 m drop adds resilience during everyday handling, so accidental drops from benches, lifts, or partially finished structures are less likely to take a battery out of service. All of these design choices support consistent cordless performance and more predictable scheduling on busy days.
The Bosch 18 Volt Lithium-Ion Battery Pack 4.0 Ah provides a 4.0 amp-hour capacity, which supports extended runtime between charges on cordless Bosch tools during typical drilling, driving, or cutting tasks.
The unique Cool br Pack Design uses advanced heat conductive housing to keep the battery cooler, supporting up to 2x longer life in repeated high-load tool applications.
The 18V CORE compact battery is rated for cold weather operation down to -4 F, so it continues working in unheated spaces or outdoor conditions where temperatures are below freezing.
The integrated fuel gauge shows fast and easy charge status, allowing users to read remaining power directly on the Bosch battery before starting or moving to another task.
The Bosch 18V CORE compact battery has a durable housing that survives a 3 m drop, helping the pack stay in service after typical on-site or shop handling impacts.
The Bosch 18 Volt Lithium-Ion Battery Pack 4.0 Ah uses lithium-ion chemistry, providing consistent power delivery and rechargeability for Bosch cordless tools.
The Bosch 18 Volt Lithium-Ion Battery Pack 4.0 Ah compact pack brings together 18V power, 4.0 Ah capacity, and a compact form, which suits professional and serious DIY users running Bosch cordless tools through full workdays.
