Wrth ABS 96 M-2 Replacement Battery 9.6V 2100mAh Ni-MH

Wurth ABS 96 M-2 9.6V Ni-MH Replacement Battery (0702 300 596)

This is a 9.6V Ni-MH battery pack rated at 2100mAh (20.16Wh), built to fit the Wurth ABS 96 M-2 cordless drill/driver. It replaces OEM part numbers 0702 300 596 and 0702 300 796. The pack slots into the ABS 96 M-2’s battery bay and connects via the standard Wurth 9.6V contact arrangement.

• ABS 96 M-2 platform fit: The ABS 96 M-2 series runs a shared 9.6V rail with a consistent cell stack configuration. All variants listed under the ABS 96 M-2 family use the same contact spacing and housing geometry, so one pack covers the full model range without adapter hardware.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge on the ABS 96 M-2 platform. The Ni-MH cells maintained stable voltage output across repeated torque applications, and the pack passed BMS handshake verification with the OEM charger without fault codes.
• Ni-MH motor-start conditioning: On first use, run the drill at half load for two full charge-discharge cycles before applying maximum torque. Ni-MH cells develop a consistent internal resistance profile across those early cycles, which reduces voltage dip on hard motor-start inrush and extends overall pack service life.

BMS overcurrent trip on trigger pull in the ABS 96 M-2

When you pull the trigger on the ABS 96 M-2, the motor draws a short inrush spike often three to five times the running current. On a new or recently stored Ni-MH pack, the BMS may read that spike as an overcurrent event and cut the pack out immediately. This is not a faulty battery. The BMS protection threshold recalibrates after two to three full work cycles as the cells build internal resistance data. If cut-outs persist after conditioning, check that the battery contacts on the tool are clean and seated fully dirty contacts raise rail resistance and amplify the voltage spike the BMS sees.

Charger not recognising the pack after storage

If the ABS 96 M-2 pack has sat unused for several months, cell voltage can drop below the charger’s acceptance threshold typically around 1.0V per cell, or roughly 7.2V at pack level for a 9.6V Ni-MH. Most OEM Wurth chargers will blink an error or do nothing when they see voltage that low. A short manual “wake” charge using a compatible Ni-MH charger set to a trickle rate (around 0.1C) for 1520 minutes can bring the pack back above the acceptance floor. Once the pack reads above 8.0V, place it on the standard charger and it should accept a normal charge cycle.
