The Steelite 21V 4.0Ah Lithium Ion Battery Pack is engineered to provide consistent and long-lasting power for all compatible Steelite cordless power tools. With a capacity of 4000mAh and a maximum voltage of 21V, it delivers an impressive 80Wh output to keep your tools running efficiently throughout demanding tasks. This battery features an intelligent protection system that safeguards against short circuits, overcharging, discharging, and overheating, ensuring safe operation during use. Its robust design has been tested to withstand drops from up to 1.5 meters, enhancing durability for both professional job sites and home projects. Additional features include a power indicator light for easy monitoring and a heat-dissipating vent that accelerates cooling to maintain optimal performance and extend battery life. The ultra-low self-discharge design helps preserve charge when not in use; however, recharging every 3 to 6 months is recommended to maximize lifespan. This battery pack is sold individually and does not include a charger or tool, making it a perfect replacement or spare for your existing Steelite cordless tool collection.
