The TCV14L2 Li-Ion battery is a compact power source designed for TCV series cordless screwdrivers. Lithium-ion cells ensure stable voltage under load, no "memory" effect, and low self-discharge, which translates into longer tool readiness. Its low weight and compact design improve the tool's ergonomics, while the 1.5 Ah capacity provides a good compromise between runtime and weight. Using the original charger and following the manufacturer's instructions is recommended for maximum lifespan and safety.
