The Bosch 18V Starter Kit with two CORE18V® 6 Ah High Power batteries and an 18V fast charger is designed to reduce downtime for users running high-demand cordless tools. Each 6 Ah battery delivers 50% more runtime and over 75% more power than a CORE18V® 4 Ah battery, making this kit a strong choice for cutting, drilling, grinding, fastening, and other jobsite applications that need steady power.
The batteries use two layers of enhanced 21700 cells, Bosch CoolPack™ 2.0 heat management, copper end plates, power rails, and a flexible circuit board to help improve efficiency and battery life. Each battery weighs 2.14 lb., offering a balance of runtime, size, and power. The included 18V fast charger delivers at least 40% faster charging than Bosch standard 18V chargers when charging a CORE18V® 6 Ah battery. Its 8-amp charging current, cooling fan, and regulated dual-mode charging help get batteries ready faster while helping protect cells during charging.
