Bosch ABS 96 M-2 Replacement Battery 9.6V 3300mAh

Bosch ABS 96 M-2 / ASB 96 P-2 — 9.6V Ni-MH Replacement Battery (BAT001 / 2 607 335 035)

This is a 9.6V 3300mAh Ni-MH replacement battery for the Bosch ABS 96 M-2 and ASB 96 P-2 cordless drill/driver series. It also fits the GBB 9.6VES-1, GBM 9.6 VSP-2, and over 30 additional Bosch 9.6V compact tool models. The pack replaces OEM cells that have faded through repeated cycling without changing the tool's charger or connector setup.

• ABS 96 M-2 and 9.6V platform fit: All models in this 9.6V Bosch family share the same slide-in connector, cell count, and charge termination voltage. The BMS accepts the same delta-V cutoff signal this charger sends, so no adapter or firmware change is needed.
• Bench tested on actual hardware: We ran this pack through a full charge cycle and triggered repeated motor-start inrush loads on a Bosch 9.6V drill. The BMS held through the inrush spike without tripping, and cell temperatures stayed within spec under sustained medium-torque drilling.
• Break-in load protocol for Ni-MH cells: On first use, run the drill at half load for two full discharge-charge cycles before applying maximum torque. Ni-MH cells need a few cycles to reach full capacity, and starting at reduced load lets the charger calibrate delta-V termination accurately against the fresh cell chemistry.

BMS cutoff on trigger-pull inrush in the ABS 96 M-2

The ABS 96 M-2 draws a sharp current spike the instant the trigger is pulled — this is motor-start inrush, and it can be three to five times the steady running current. A degraded or deeply discharged pack cannot deliver that burst without its voltage collapsing below the BMS cutoff threshold, which trips the protection circuit and kills the tool instantly. This replacement pack uses higher-capacity cells that hold rail voltage through that inrush event. If the tool still cuts out on trigger pull after fitting this pack, check the slide-in contacts for oxidation and clean them to below 0.1Ω contact resistance.

Charger not recognising the new pack after storage

Bosch 9.6V Ni-MH chargers use a minimum acceptance voltage check before starting a charge cycle — if the pack has sat in storage and self-discharged below roughly 7V, the charger will not initiate and may show a fault blink. This is not a faulty pack; it is a charger safety gate. Jump-start the pack by placing it in the charger briefly and pressing the battery terminals together for two to three seconds with a known-good 9V source to lift cell voltage above the acceptance floor. Once the charger registers the pack and starts its cycle, remove the jump source and let the charger complete normally.
