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 / P18TX / S18P Series — 18V Li-ion Replacement Battery
This is an 18V 3000mAh (54Wh) Li-ion battery pack for the Atlas Copco LokTor torque wrench range. It fits the LokTor H18, P18T, P18TX, and S18P, along with eight additional LokTor variants that share the same 18V platform. These are precision cordless torque tools used in automotive assembly lines and industrial fastening — continuous operation matters.
- LokTor platform compatibility: The H18, P18T, P18TX, and S18P share the same 18V battery rail, connector footprint, and BMS communication protocol. One pack works across all of them — no adapters, no firmware mismatch.
- Bench tested on actual hardware: We ran this pack through repeated torque-cycle loads on the LokTor platform. The BMS handled motor-start inrush without tripping, held voltage within spec under sustained fastening sequences, and discharged to cutoff cleanly without cell reversal.
- LokTor motor inrush conditioning: On first use, run the tool at half torque for two full cycles before applying maximum torque settings. This lets the BMS profile the motor's inrush current signature and calibrate its overcurrent threshold before you hit peak fastening loads.
BMS overcurrent trip on trigger pull in high-torque fastening
The LokTor's motor draws a sharp inrush spike the instant the trigger is pulled — especially at maximum torque settings. A new pack with a conservatively set BMS can interpret that spike as a fault and cut power before the fastener even moves. This is not a defective battery. The BMS needs two to three cycles to log the motor's inrush profile and widen its overcurrent window accordingly. If cutoff persists after conditioning cycles, check the battery rail contacts for oxidation — resistance at the contact point amplifies the apparent voltage drop the BMS sees.
Charger shows blinking red and never accepts the new pack
A LokTor battery stored in a depleted state can drop below the charger's acceptance voltage threshold — typically under 12V for an 18V Li-ion pack. The charger's protection circuit reads this as a damaged or over-discharged cell and refuses to begin a charge cycle. Most Atlas Copco chargers have a recovery or "wake" mode: hold the battery in the charger for 10–15 minutes while the charger trickle-feeds current at a sub-amp rate to bring cells back above the acceptance floor. Once the pack reads above approximately 14V, the charger should switch to normal CC/CV charge and the indicator will go solid or green.

Frequently Asked Questions
The LokTor cuts out the moment I pull the trigger hard — is the battery faulty?
This is a BMS overcurrent trip, not a defective cell. The motor's inrush current at full torque exceeds the overcurrent threshold the BMS defaults to on a new or storage-rested pack. Run two to three light-load fastening cycles first to let the BMS log the motor's actual current signature. If it still trips after conditioning, clean the battery rail contacts — resistance at the connector inflates the voltage sag the BMS measures and tightens the trip threshold further.
The tool feels weak and bogs down halfway through a torque sequence — full charge shows on the indicator. What's wrong?
Voltage sag under sustained load is the likely cause, not low state-of-charge. When the LokTor motor holds torque for several seconds, cell internal resistance causes the rail voltage to droop — the tool loses drive force even though the pack isn't empty. Check the battery contact pins and socket for corrosion or debris; high contact resistance compounds the sag. If the contacts are clean, the cells may have degraded from repeated shallow cycling — a 3000mAh pack cycled constantly between 80% and 100% loses usable capacity faster than one discharged to 30–40% before recharging.
Performance drops noticeably when we're running the LokTor in an unheated workshop in winter — what's happening?
Li-ion internal resistance rises sharply below 5°C, and the LokTor's torque output depends directly on how cleanly the pack can deliver current under load. At low temperatures the cells physically cannot sustain the same current delivery — voltage sags faster and the BMS may trip earlier than it would at room temperature. Store the battery pack indoors at room temperature before the shift and install it in the tool just before use. A pack that starts the day at 20°C will hold usable voltage under load significantly longer than one that sat at 2°C overnight.
