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.

DOLMAR AH-3756 XE3 Series — 14.4V Li-ion 6000mAh Replacement Battery
This is a 14.4V lithium-ion battery rated at 6000mAh (86.4Wh), built to replace the original pack in DOLMAR cordless power tools. It fits the AH-3756 XE3, AH1853H, AH3766X3, AH-3766 XE3, and seven additional models in the same platform. The connector and BMS communication protocol match the original charger and tool handshake.
- AH-3756 XE3 platform compatibility: These models share a common 14.4V cell configuration, connector pinout, and BMS voltage thresholds. The tool's electronics expect the same charge termination signal and overcurrent limits across the platform — this pack meets those specs.
- Bench tested on actual hardware: We ran charge and discharge cycles on this pack using a Dolmar-compatible charger and monitored BMS response under simulated motor-start inrush loads. The overcurrent protection tripped and reset correctly at expected thresholds.
- Motor break-in cycle: On first use, run the tool at half load for two cycles before applying full torque. This lets the BMS log the inrush current profile for your specific motor and calibrate its overcurrent trip threshold accordingly.
BMS cutoff on motor-start inrush with drills and circular saws
Cordless drills and saws draw a spike of current the moment the trigger engages — often two to three times the running draw. The BMS watches this spike against a stored threshold. A new or cold pack can register the surge as a fault and cut the output circuit before the motor reaches speed. Running the pack through a full charge-discharge cycle first lowers the BMS trip sensitivity and aligns the threshold to the actual motor characteristics. After two conditioning cycles, mid-trigger cutoffs on a healthy motor typically stop occurring.
Charger shows a blinking or error light on a new pack after storage
Li-ion cells self-discharge during storage. If the pack drops below the charger's acceptance voltage — typically around 10V on a 14.4V pack — the charger will refuse to enter its normal charge cycle and signal a fault. This is a protective threshold, not a defective unit. To recover the pack, hold it in the charger for 10–15 minutes; most DOLMAR-compatible chargers include a low-voltage recovery mode that trickle-charges the cells back above the acceptance floor before switching to the main charge curve. Once the cell voltage climbs above roughly 10.8V, the charger should step into its standard CC/CV cycle.

Frequently Asked Questions
My DOLMAR drill cuts out the instant I pull the trigger hard — then comes back after a few seconds. What's happening?
That's a BMS overcurrent trip on motor-start inrush. The trigger-pull spike exceeds the BMS's threshold, and the protection circuit opens briefly before resetting. Run the pack through two full charge-discharge cycles at moderate load — this allows the BMS to log the inrush signature and recalibrate its trip point. If it still trips on a new pack, check that the tool's rail contacts are clean and seating flush, since added contact resistance amplifies the apparent current spike.
The tool feels strong on light cuts but bogs badly when I push it through hardwood or thick material. Battery or tool?
That's voltage sag — under heavy load, internal cell resistance causes the pack voltage to drop, and the tool loses torque. On a new pack, the usual cause is high contact resistance at the rail terminals; clean both the tool and battery contacts with isopropyl alcohol and check for corrosion or bent blades. If sag continues after cleaning, measure the pack voltage under load with a multimeter — a healthy 14.4V pack should stay above 12.8V under sustained draw. A reading below 12V under moderate load means the cells have degraded and the pack needs replacement.
This battery charges fine in summer but the tool feels half-dead on cold mornings. Is the pack failing?
Li-ion internal resistance rises sharply below 5°C, which reduces the current the cells can deliver and causes voltage to sag earlier in the discharge curve. The pack is not failing — it's behaving as expected chemistry. Warm the battery to room temperature before use; store it indoors overnight rather than in a shed or vehicle. A pack at 20°C will deliver noticeably more torque than the same pack at 2°C, with no change in the cell's underlying capacity.
