Before You Buy
Ensure you possess a compatible rapid charger from the same manufacturer and platform (or purchase an official Starter Kit bundled with a charger). Lithium-ion packs should not be stored completely depleted; maintain approximately 40% to 60% charge if storing for extended workshop downtime.
When browsing merchant listings on Amazon, verify whether the listing designates a single bare battery pack, a multi-pack, or a complete kit with high-speed charging dock.
