Craftsman 11013 14.4V Ni-MH Replacement Battery 2000mAh

Craftsman 315.11453 Series — 14.4V Ni-MH Replacement Battery (11013)

This is a 14.4V, 2000mAh Ni-MH replacement battery for Craftsman cordless drills and drivers in the 315.11453 series. It fits multiple 315-series models including 315.1154 and 315.115400, as well as the 10153 platform. OEM part numbers covered include 11013, 11044, 130279002, 1325101, and 1322522.

• 315-series platform compatibility: These models share a 14.4V power rail, the same battery bay footprint, and identical BMS handshake requirements. One pack covers the full cluster without modification.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on a 315-series drill. The BMS logged accurate state-of-charge from cycle one, and overcurrent protection triggered cleanly at the expected motor-start inrush threshold.
• Break-in load protocol: On first use, run the drill at half load for two cycles before high-torque applications. This lets the BMS profile the motor inrush current draw and set its overcurrent thresholds accurately before you hit full load.

BMS cutoff on motor-start inrush in 315-series drills

When you pull the trigger on a cordless drill, the motor draws a current spike several times higher than its running current — this is inrush. On a fresh or recently stored Ni-MH pack, the BMS may not yet have a calibrated overcurrent threshold, so it cuts the circuit the moment that spike hits. The fix is two break-in cycles at reduced load before full-torque use. After those cycles, the BMS sets its trip point around the actual inrush curve of your motor and stops nuisance-tripping.

Tool bogs and loses torque under sustained load

If the drill runs normally at first but loses speed or torque under sustained pressure, the cause is usually voltage sag — the terminal voltage dropping under load due to high internal resistance. On Ni-MH cells, this gets worse after repeated shallow cycling, where the battery is topped up before it fully discharges. Check the battery rail contacts on the tool for oxidation or debris first — resistance at that joint amplifies sag. If contacts are clean and sag persists, run the pack through two full discharge-and-charge cycles to reset the cell balance; resting voltage on a healthy pack should read 14.4V at no load.
