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.

Atlas Copco LokTor H18 / P18T / S18P Series — 18V Li-ion 6.0Ah Replacement Battery
This is an 18V Li-ion battery rated at 6000mAh (108Wh), built to fit the Atlas Copco LokTor H18 and its platform siblings including the P18T, P18TX, and S18P. The LokTor series are precision torque wrenches used in industrial fastening and automotive assembly. Voltage and connector format match the original pack exactly.
- LokTor platform compatibility: The H18, P18T, P18TX, and S18P share the same 18V battery rail, connector housing, and BMS handshake protocol — which is why a single battery services the full range. Swapping across models in the same fleet is straightforward.
- Bench tested on actual hardware: We ran this pack through repeated high-torque fastening cycles on the LokTor platform. The BMS held the voltage rail steady through motor-start inrush spikes and did not trip overcurrent protection under rated load conditions.
- Break-in procedure for torque accuracy: On first use, run the tool at half the target torque setting for two full fastening cycles before pushing to maximum torque. This lets the BMS profile the motor's inrush current draw and calibrate its overcurrent threshold before you put the pack under full industrial load.
BMS cutoff on LokTor motor-start inrush surge
Precision torque wrenches pull a sharp current spike the instant the motor engages — the LokTor is no exception. On a cold or freshly installed pack, the BMS overcurrent threshold may not yet account for that inrush, triggering a protective cutoff before the tool reaches operating speed. This is a threshold calibration issue, not a faulty battery. Running two half-load cycles first teaches the BMS the motor's actual inrush profile and prevents nuisance trips at full torque.
Charger not recognising the pack after storage
If the charger shows a blinking red light or no response when a new or stored pack is inserted, cell voltage has likely dropped below the charger's acceptance threshold — typically around 10V for an 18V pack. The BMS will not allow a charge cycle to begin until minimum cell voltage is confirmed. Place the pack on the charger, remove it after 30 seconds, then reinsert — repeating this two or three times can prompt the charger to recognise the pack and begin a recovery charge. If cell voltage has dropped below 8V, the BMS may have locked the pack permanently to prevent unsafe charging.

Frequently Asked Questions
My LokTor cuts out the moment I pull the trigger hard — but recovers if I ease off. What's happening?
That's a BMS overcurrent trip triggered by the motor-start inrush spike, not a failing battery. The current surge when the LokTor engages under load briefly exceeds the BMS protection threshold, causing an instant shutoff. Run two cycles at half your target torque setting first — this profiles the inrush draw and raises the effective trip threshold. After those two cycles, full-torque pulls should hold without cutoff.
The tool bogs down and loses torque accuracy mid-sequence, even with a charged battery. What causes that?
Voltage sag under sustained load is the most likely cause — the cell voltage drops under draw, pulling the rail below what the motor controller expects, and torque output falls with it. Check the contact points between the battery and tool for oxidation or debris; even a small increase in contact resistance amplifies voltage sag significantly. Clean the contacts with a dry cloth and reseat the pack firmly. If sag persists after cleaning, the cells may have degraded from repeated shallow cycling — charge the pack to 100% and run it through a full deep discharge cycle before assessing further.
This battery performs fine indoors but feels noticeably weaker in an unheated workshop in winter. Is that normal?
Yes — Li-ion internal resistance rises sharply below 5°C, reducing the current the cells can deliver without voltage sag. The LokTor's motor controller interprets that sag as low charge and may reduce output or trigger a low-voltage cutoff earlier than expected. Store the battery at room temperature and bring it out to the workshop only when you're ready to use it. A pack that starts at 20°C will maintain its voltage rail through motor-start inrush far better than one that's been sitting in a cold van overnight.
