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 13618-2G / BAT160 Series — 18V Ni-MH Replacement Battery (2 607 335 266)
This is an 18V, 3000mAh Ni-MH replacement battery for the Bosch 13618-2G cordless drill/driver and compatible 18V Bosch power tools. It matches the original cell count and voltage rail, so the tool's trigger response and torque output behave as expected. OEM part numbers covered include BAT160, BAT180, BAT181, BAT189, and 2 607 335 266 among others.
- 13618-2G and 1644 series compatibility: These models share the same 18V slide-pack form factor, connector pin layout, and BMS handshake protocol. Any battery that satisfies the voltage rail and thermistor signal on one will seat and communicate correctly on the others.
- Bench tested on actual hardware: We cycled this pack through repeated trigger-pull inrush events on a drill platform and monitored BMS overcurrent response. The protection circuit handled motor-start spikes without nuisance tripping under normal fastening loads.
- Motor inrush conditioning on first use: Run the drill at half load — driving standard screws, not lag bolts — for the first two charge cycles. This lets the BMS log the motor's inrush current signature before it sets its overcurrent trip threshold for high-torque applications.
BMS cutoff on motor-start inrush during high-torque trigger pulls
Ni-MH packs that have been in storage often present elevated internal resistance on the first few cycles. When you pull the trigger hard on a fresh or recently stored pack, the motor inrush current spike can exceed the BMS overcurrent threshold before the cells have warmed up. The BMS trips as a protective measure — the tool cuts out instantly, not gradually. Two or three partial-load cycles bring cell resistance down and shift the trip threshold back into a normal operating range.
Tool bogs under sustained load but doesn't cut out completely
This is voltage sag — not a dead cell. Under sustained motor draw, internal resistance causes the pack voltage to drop below the tool's stable operating range, and the motor loses torque without the BMS triggering a full cutoff. Check the battery terminal contacts on both the pack and the tool for oxidation or debris, as poor contact resistance amplifies sag. Clean contacts with isopropyl alcohol and test again. If sag persists after cleaning, measure resting pack voltage — a healthy 18V Ni-MH pack should read at or above 21V fully charged.

Frequently Asked Questions
My Bosch 13618-2G cuts out the instant I pull the trigger hard — is the battery faulty?
This is a BMS overcurrent trip, not a failed cell. On a new or stored Ni-MH pack, internal resistance is elevated, and the motor-start inrush spike on a hard trigger pull can exceed the BMS threshold before the cells stabilise. Run the drill at light load — standard screws, no spade bits — for the first two cycles. After that conditioning, resting cell resistance drops and the trip threshold shifts back into range for high-torque pulls.
The charger never recognises this pack — light stays solid red and won't move to green.
A Ni-MH pack that has sat discharged for months can drop below the charger's acceptance voltage floor. Most Bosch 18V chargers reject packs reading under roughly 10–12V at the terminals and signal this with a locked red indicator. Measure the pack voltage with a multimeter before charging — if it reads below 10V, the pack needs a recovery charge at low current before the standard charger will engage. Some third-party chargers include a manual recovery or "wake" mode; use that, then transfer to the Bosch charger once the pack reads above 12V.
The drill runs noticeably weaker in cold weather — does the battery need replacing?
No — this is normal Ni-MH behaviour below about 10°C. Cold temperatures raise internal cell resistance, which increases voltage sag under load and reduces the torque the motor can sustain. Bring the pack indoors to room temperature for 30 minutes before use. If the tool still runs weak after the pack has warmed up, check terminal contact resistance — oxidised contacts worsen sag and mimic cold-weather symptoms even at normal temperatures. Clean contacts with isopropyl alcohol and retest.
