The Bosch GSA18VLI Cordless Reciprocating Saw offers the highest material removal rate and cutting performance in its class per battery charge. It features an extremely robust and durable 4-pole high-performance motor for a long lifetime, and a compact design with low weight (only 2.3 kg) for comfortable working, especially in tight spaces and overhead. The unique Bosch Premium lithium-ion technology provides 400% longer lifetime and unbeatable battery runtime. Bosch Electronic Cell Protection (ECP) protects the battery against overload, overheating, and deep discharge, while Bosch Electronic Motor Protection (EMP) protects the motor against overload and ensures a long lifetime. The practical battery charge level indicator constantly shows how much energy is left in the battery. The gear head can be rotated in 90 degree steps, and the handle can be used on the right or left. The anti-rotation protective guard is quickly and easily adjustable, providing reliable protection. The Bosch Hyper Charge feature allows batteries to be charged to 75% after just half of the charge time. There is no memory effect, meaning the battery can be charged at any time, regardless of the charging state, without damaging the cells. The Bosch 5.0Ah Cool Touch Batteries offer an additional 25% longer runtime compared to Bosch 18V 4.0 Ah Coolpack batteries and up to 100% longer lifetime thanks to the Bosch Cool Pack. They are 100% compatible with existing tools and charger ranges, with a full charge time of 50 minutes. This Flexible Power System comes with a 2-year Bosch Battery Warranty and Premium Service. The 5.0 Ah Coolpacks have finer cell windings than 3.0 Ah batteries, allowing for more power density and less electrical resistance, resulting in greater fuel efficiency (run-time per Ah). Users benefit from not needing to change battery packs as often and the fastest charging solution for 18V 5.0Ah battery packs on the market, with more run time thanks to the Bosch Coolpac.
