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

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

This is a 9.6V Ni-MH replacement battery rated at 3300mAh (31.68Wh) for the Wurth ABS 96 M-2 cordless drill/driver. It fits the ABS 96-M2 and ABS 96 M2 variants across the same platform. The connector and cell pack match the original pack dimensions of 108.66 x 53.00 x 104.70mm.

• ABS 96 M-2 platform fit: These model variants share the same 9.6V cell configuration, battery housing footprint, and contact arrangement. The pack slots into the same bay without modification and the charger handshake runs as expected with the original Wurth charging unit.
• Bench tested on actual hardware: We cycled this pack through full charge and discharge sequences and monitored the BMS response under motor-start inrush loads. Cell voltage stayed stable across the discharge curve and the protection circuit held within expected thresholds throughout.
• Break-in load protocol: On first use, run the drill at half load — light driving tasks, not full torque applications — for the first two cycles. This lets the BMS profile the motor's inrush current signature before overcurrent thresholds lock in, reducing the chance of a nuisance trip on the first hard fastener.

BMS cutoff on ABS 96 M-2 motor-start inrush surge

When you pull the trigger on a drill, the motor draws several times its running current in the first milliseconds — this is inrush. Ni-MH packs use a protection circuit that can trip if that spike exceeds the overcurrent threshold, cutting power instantly. On a new or recently stored pack, the BMS has not yet mapped the motor's inrush profile and may be more sensitive to that initial spike. Running two break-in cycles at reduced load trains the circuit and lowers false trip frequency on heavy fastening work.

Tool bogs under load mid-job — not a cutout, just weak output

If the drill slows noticeably under torque but does not cut out completely, voltage sag is the likely cause. This happens when contact resistance at the battery terminals rises — either from oxidised contacts on the pack or the tool's battery bay. Clean both contact points with isopropyl alcohol and a firm wipe before reseating the pack. If sag continues after cleaning, check rail voltage at the tool contacts under load — it should not drop below 8.4V on a freshly charged 9.6V Ni-MH pack.
