Completes the main circuit for both tool and charger.

While it's theoretically possible to rebuild a Hart battery by replacing the internal 18650 cells, it's for safety and warranty reasons. Lithium-ion batteries are volatile and sensitive to soldering heat, and a proper rebuild requires a spot welder for nickel strips—not a soldering iron. The internal BMS also locks onto a specific cell configuration. Given Hart's budget-friendly pricing ($40 for a 1.5Ah battery), replacement is almost always the safer, more cost-effective option.
