Bosch GXS18V-11N25 18V CORE18V 4.0 Ah Batteries with GAL18V-40 4-Amp Fast Charger Starter Kit

The Bosch GXS18V-11N25 18V CORE18V 4.0 Ah Battery and Charger Starter Kit operates as a cordless power solution engineered to supply high-current power to 18V power tools across masonry drilling, metal grinding, and wood cutting applications. Featuring two GBA18V40 4.0 Ah compact batteries built with 21700 lithium-ion cells and a GAL18V-40 4-amp fast charger, this power kit provides 72 Wh energy capacity per battery while utilizing CoolPack 2.0 thermal dissipation housings. Weighing 1.10 pounds per pack and fully integrated into the multi-brand AMPShare system platform, this battery kit recharges a 4.0 Ah pack to 100% capacity in 65 minutes to eliminate tool downtime.

Best Used For:

  • Continuous Overhead Masonry Drilling & Grinding: Powering 18V rotary hammers and angle grinders with lightweight 1.10-pound packs to reduce arm fatigue during overhead work.
  • High-Demand Wood Cutting & Framing Operations: Delivering steady current to 18V circular saws and reciprocating saws cutting heavy dimensional timber.
  • Multi-Brand AMPShare Fleet Management: Supplying uniform 18V power across Bosch cordless tools and participating AMPShare alliance jobsite equipment.

Key Performance & Safety Features

  • Advanced 21700 Lithium-Ion Cells: High-density single-layer cell configuration delivers 60% more power and double the runtime of standard 2.0 Ah battery packs.
  • CoolPack 2.0 Thermal Management: Radiant heat mitigation housing pulls destructive heat away from internal cells to extend total battery cycle life.
  • Low-Resistance Internal Copper Rails: Copper end plates and robust power rails lower electrical resistance to maintain voltage stability under high tool loads.
  • GAL18V-40 4-Amp Fast Charger: High-amperage output supplies 4.0 amps of charging current to complete a full 0% to 100% recharge cycle in 65 minutes.
  • Regulated Dual-Mode Charging Profile: Smart electronics fast-charge the battery up to 80% capacity before tapering power into long-life mode for the final 20%.
  • Universal AMPShare System Platform: Cross-compatible with all Bosch 18V lithium-ion power tools, chargers, and AMPShare partner equipment lines.

Pro-Tip: Allow warm CORE18V batteries to rest for a few minutes after heavy high-draw tool use before snapping them into the GAL18V-40 charger. Giving the internal CoolPack 2.0 housing a brief moment to dissipate surface heat allows the charger's smart sensors to immediately begin fast 4-amp charging without initiating a thermal delay sequence.
