Battery Care Tips
Battery Care Tips
🔹 Getting Started
Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.
🔹 Keep It Healthy
Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.
Delivery and Shipping
Delivery and Shipping
🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Bosch GSR 9.6-1 / GSR 9.6-2 — 9.6V Ni-MH Replacement Battery (2 607 335 707)
This is a 9.6V, 1500mAh Ni-MH replacement battery for the Bosch GSR 9.6-1, GSR 9.6-2, GSR 9.6V, and GDR 9.6V cordless drill-drivers. It replaces OEM packs under part numbers 2 607 335 707, BAT100, BAT119, BAT048, and several others in the same family. When the original pack stops holding charge or drops voltage mid-job, this pack slots into the same bay and runs the same charger.
- GSR 9.6 series compatibility: The GSR 9.6-1, 9.6-2, 9.6V, and GDR 9.6V share the same 9.6V slide-in bay, connector pinout, and charge communication line. Any pack meeting those three specs works across all four platforms without modification.
- Bench tested on actual hardware: We cycled this pack through repeated trigger-pull inrush loads on a GSR 9.6-1. The BMS held through repeated clutch-engagement spikes without tripping, and cell voltage recovered cleanly after each load event.
- Ni-MH cycle conditioning on first use: On first use, run the drill at half load for two cycles before applying maximum torque. This lets the BMS profile the motor's inrush current draw and set overcurrent thresholds accurately before you hit full load.
BMS overcurrent trip on motor-start inrush in the GSR 9.6 series
When you pull the trigger on a Bosch GSR 9.6-1, the motor draws a current spike several times higher than its running draw — this is inrush current. A Ni-MH BMS that hasn't profiled the motor yet can read this spike as a fault and cut output instantly. On unconditioned packs, this trips the protection circuit before the motor has time to spin up. Running two half-load cycles first gives the BMS enough data to distinguish normal inrush from a genuine overcurrent event.
Tool bogs under load or feels weaker than the original pack
If the drill runs but loses torque under load, the cause is usually voltage sag — the rail voltage drops under current draw because of resistance at the battery contacts or degraded cell internal resistance. Clean the battery contacts on both the pack and the drill bay with isopropyl alcohol and check for corrosion or carbon buildup. Under moderate load, a healthy 9.6V Ni-MH pack should hold above 8.4V at the terminals. If voltage reads below that under load, the contact resistance is the first place to check before assuming the cells are at fault.

Frequently Asked Questions
My Bosch GSR 9.6-1 cuts out the moment I pull the trigger — is that the battery tripping?
Yes — that's a BMS overcurrent trip caused by motor-start inrush current. On a fresh or storage-rested Ni-MH pack, the protection circuit hasn't profiled the motor's startup spike yet and reads it as a fault. Run the drill unloaded two or three times to let the BMS calibrate, then move to light load before applying full torque. If it still cuts out, check that the battery contacts in the bay are clean and making solid contact — high resistance at the connector amplifies the apparent current spike the BMS sees.
The charger never starts a charge cycle on the new pack — light just blinks and stops.
A Ni-MH charger checks cell voltage before it starts a cycle. If the pack sat in storage, individual cells can drop below the charger's acceptance threshold — typically around 0.9V per cell, or roughly 8.6V total for a 9.6V pack. Put the pack in a warm room (around 20°C) for 30 minutes and try again. If the charger still won't accept it, some Bosch 9.6V chargers have a recovery or "refresh" mode — check your charger model and activate that mode to trickle-charge the pack back into acceptance range before a normal cycle begins.
The drill works fine indoors but bogs out badly in cold weather — what's happening?
Ni-MH cell internal resistance rises significantly below 5°C, which causes the pack voltage to sag hard under motor load. At around 0°C, you can lose 20–30% of usable capacity and see noticeable torque drop on anything heavier than light fastening. Warm the battery to room temperature before use — keep a spare pack inside while you work outdoors and swap when the active pack starts to feel sluggish. A pack that reads 9.6V at rest but drops below 8.0V under load in the cold is behaving normally for the chemistry, not failing.
