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.

Itowa Winner 2G Version 2 — 3.6V Ni-MH Replacement Battery (BT3613MH2)
This is a 3.6V, 2000mAh Ni-MH replacement battery for the Itowa Winner 2G Version 2 crane remote control. It fits the wireless handset used to operate overhead cranes and industrial hoists. The OEM part number is BT3613MH2.
- Winner 2G Version 2 fitment: This battery shares the same voltage rail, connector footprint, and physical dimensions (61.40 × 49.50 × 22.30mm) as the factory cell. The remote's power circuit draws directly from a single 3.6V Ni-MH pack — no adapter or wiring change needed.
- Bench tested on actual hardware: We ran this cell through the Winner 2G Version 2 handset and confirmed stable output across button activation cycles, including the inrush current spike that occurs when the remote signals a solenoid or relay command. The BMS held without dropout.
- First-use charge on crane remotes: Ni-MH cells ship at partial storage voltage — typically 3.2–3.4V. Insert the battery and run a full charge cycle before taking the remote onto the crane floor. Attempting to operate at storage voltage shortens the usable charge cycle and may trigger low-battery warnings immediately after swap.
Why the Winner 2G Version 2 drops power during solenoid activation
When the remote transmits a crane movement command, the internal relay or solenoid driver draws a short inrush current spike that briefly loads the battery harder than idle transmission does. A partially discharged or degraded cell can't sustain voltage through that spike, and the remote's microcontroller resets or cuts out. This isn't a remote fault — it's a cell voltage problem. A fully charged 3.6V Ni-MH cell at 2000mAh handles these spikes without a dropout. If the issue persists on a fresh battery, check that the cell is fully charged before each shift.
Remote showing low battery immediately after new cell install
This happens because Ni-MH batteries leave storage at reduced voltage — around 3.2V — not at full charge. The Winner 2G Version 2 reads cell voltage on startup and flags anything below its threshold as low. The fix is straightforward: connect the battery to its charger for a full cycle before first use. Once the cell reaches its nominal 3.6V charge state, the low-battery indicator clears and the remote operates normally.

Frequently Asked Questions
My Itowa Winner 2G Version 2 remote won't turn on at all after sitting unused for several months — is the battery dead?
Most likely the Ni-MH cell has self-discharged below the point the remote's circuit can start from. Connect the battery to its charger for at least 30 minutes before attempting to power the remote on. Ni-MH cells don't enter the same hard BMS lockout that Li-ion cells do, but a deeply discharged cell won't deliver enough voltage to trigger the remote's startup sequence. After a full charge cycle, the remote should power on normally.
The crane remote cuts out mid-operation when I activate a movement command, but works fine on the menu screen — what's causing this?
The solenoid or relay driver inside the remote pulls a short inrush current spike each time a movement command transmits. A cell that's partially discharged can't hold its voltage through that spike, so the microcontroller resets. This only shows up under load — which is why the remote appears fine at rest. Charge the battery fully before each shift and confirm the cell is reading at or near 3.6V before going on-site.
The E-stop response on the Winner 2G Version 2 feels slower than it used to — could the battery be the cause?
Yes. E-stop response time on this remote is voltage-dependent — the transmitter's output power drops as the cell discharges, which can add latency to the signal reaching the crane's receiver. This is a safety-critical function, so treat it as a hard rule: never operate the remote for E-stop duty on a partially charged cell. Charge fully to 3.6V before any shift where the E-stop may be needed.
