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 13614 Series — 14.4V Ni-MH Replacement Battery (BAT140)
This is a 14.4V, 1500mAh Ni-MH replacement battery for the Bosch 13614 and 13614-2G cordless drill/drivers, along with the 15614, 1661, and over 48 additional compatible models. It cross-references OEM part numbers including BAT038, BAT040, BAT041, BAT159, and the 2 607 335 264 series. The connector and terminal layout match the original Bosch slide-pack form factor used across this voltage platform.
- 14.4V Bosch slide-pack platform: The 13614, 15614, and 1661 models share the same 14.4V rail and slide-pack connector geometry. Bosch standardised this interface across the generation, so one battery fits the full lineup without adapter modifications or terminal rework.
- Bench tested on actual hardware: We ran this pack on a 13614-2G under repeated trigger cycles, monitoring cell voltage recovery between loads. The BMS held cutoff thresholds correctly and the charger handshake completed on first insertion without fault codes.
- Ni-MH break-in on high-torque drills: Run the 13614 at half load for the first two cycles before driving large fasteners or using maximum torque settings. Ni-MH cells need initial cycling to equalise charge across the cell string — skipping this can cause premature voltage drop under load.
BMS overcurrent trip on 13614 motor-start inrush
The 13614 draws a sharp inrush current the instant the trigger closes — this spike is significantly higher than the steady running current. On a new or cold Ni-MH pack, the BMS may read that spike as an overcurrent event and cut the output rail before the motor reaches speed. This is more common in cold conditions where internal cell resistance is elevated. After a cutout, remove the pack, wait 60 seconds, and reinsert — this resets the BMS latch without needing a charger cycle.
Charger not recognising the pack after storage
Ni-MH packs that have sat unused for several months can self-discharge below the voltage threshold the Bosch charger uses to confirm a valid pack is present. The charger sees a voltage too low to begin a charge cycle and either blinks an error or does nothing. To recover, briefly connect the pack to a known-good Ni-MH charger set to trickle or recovery mode until cell voltage rises above 10V total. Once the pack crosses that threshold, re-insert it into the Bosch charger and the standard charge cycle will initiate normally.

Frequently Asked Questions
My Bosch 13614 cuts out the instant I pull the trigger — is this the battery or the tool?
That's a BMS overcurrent trip, not a tool fault. The motor-start inrush current on the 13614 spikes hard, and a new or cold Ni-MH pack can register that spike as an overcurrent event before the motor even reaches speed. Remove the pack, wait 60 seconds, and reinsert — this clears the BMS latch. If it persists across multiple attempts, run two partial break-in cycles at half load first to let the BMS profile the inrush draw.
The drill runs fine at first but bogs down badly after a few holes — what's causing that?
That's voltage sag under sustained load, not a dead battery. As the Ni-MH cells heat up during repeated use, internal resistance rises and the pack can no longer hold the voltage rail steady under torque demand. Check the slide-pack contacts on both the battery and the drill for oxidation or debris — even minor contact resistance compounds the sag. Clean the contacts with isopropyl alcohol and let the pack cool to room temperature between heavy drilling sessions.
The Bosch charger never goes green on this new pack — it just sits there blinking. What's wrong?
A pack that's been in storage often self-discharges below the minimum acceptance voltage the Bosch charger requires before starting a charge cycle. The charger interprets the low voltage as a fault rather than a depleted cell. Connect the pack to any compatible Ni-MH trickle charger until the total pack voltage climbs above 10V, then transfer it back to the Bosch charger — the standard charge cycle will engage once the pack crosses that threshold.
