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.

GreenWorks 2000007 Series — 24V Li-ion Replacement Battery (29842)
This is a 24V lithium-ion replacement battery rated at 2000mAh (48Wh), built to the same electrical spec as the original GreenWorks 29842 pack. It fits a wide range of GreenWorks 24V cordless tools including the 2000007, 2000107, 20362 Chainsaw, and 2100007, among others. Slot it into the same rail connector and the tool powers on without any reconfiguration.
- 24V platform fit — 2000007 and related models: GreenWorks built this tool family around a shared 24V rail and a standardised slide-in connector with a common BMS handshake protocol. Any pack carrying OEM part numbers 29842, 29852, 29322, G24B2, 29807, or 29837 runs on the same electrical architecture — same contact pitch, same communication line.
- Bench tested on actual hardware: We cycled this pack through repeated trigger-pull events on a 24V GreenWorks platform and monitored BMS response. The overcurrent protection tripped at the correct threshold during motor-start inrush and recovered cleanly without requiring a manual reset.
- First-use load conditioning: Run the tool at half load for two cycles before maximum torque applications. This allows the BMS to profile the motor's inrush current draw and set accurate overcurrent protection thresholds before you push the pack hard.
BMS cutoff on motor-start inrush surge in 24V GreenWorks tools
When you pull the trigger on a chainsaw or drill, the motor draws a spike of current well above its running load — this is inrush current, and it lasts only milliseconds. A new or cold pack can trigger the BMS overcurrent protection if the cell internal resistance is slightly elevated, because the voltage drop across the cells at that moment looks like a fault condition to the BMS. The pack shuts off before the motor reaches speed. Warming the pack to room temperature before use and running a half-load break-in cycle lowers internal resistance enough that the BMS reads the inrush as normal startup rather than a fault.
Charger blinking red and refusing to accept the pack after storage
Li-ion chargers have a minimum acceptance voltage — typically around 2.5V per cell. If a pack has self-discharged below that threshold during storage, the charger detects an out-of-range voltage and blinks red instead of beginning a charge cycle. This is a protective lockout, not a faulty charger or a dead pack. To recover the pack, briefly connect it to a compatible 24V GreenWorks tool and press the trigger for a few seconds — this nudges cell voltage upward through residual charge. Then reconnect to the charger; once cells read above the acceptance floor, the charger will switch to a normal charge cycle.

Frequently Asked Questions
My GreenWorks chainsaw cuts out the moment I squeeze the trigger — is that the battery or the tool?
That's the BMS tripping on motor-start inrush current, not a tool fault. The spike of current drawn the instant the motor starts can exceed the BMS overcurrent threshold, especially if the pack is cold or brand new. Warm the battery to room temperature before use and run two half-load cycles to let the BMS calibrate to the motor's inrush profile. After that break-in, trigger-pull cutouts typically stop.
The tool bogs down and loses power under sustained chainsaw cuts — battery or motor issue?
This is voltage sag under heavy load, and it usually points to elevated contact resistance between the pack rail and the tool's battery terminals. Check both sets of contacts for corrosion or debris and clean them with a dry cloth. A worn contact surface can drop the voltage at the rail enough for the tool to lose torque without the BMS ever tripping a fault. If contacts are clean and the sag persists, check cell temperature — sustained cutting loads heat both the motor and the cells, and the BMS will throttle output before triggering a full thermal cutoff.
My GreenWorks 24V pack lost capacity after a few months even though I barely used it — what happened?
Shallow cycling degrades Li-ion cells faster than most users expect. If the pack was repeatedly discharged only 10–20% and topped back up, the cells never completed full charge-discharge cycles, which compresses the usable capacity range over time. Li-ion cells also self-discharge during storage; if the pack sat for weeks between uses, repeated partial recovery from low voltage stresses the cell chemistry. Going forward, run the pack down to around 20% charge before recharging to keep full cycle depth and slow capacity fade.
