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

🔹 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 1 — 3.6V Ni-MH Replacement Battery (BT3613MH2)

This is a 3.6V, 2000mAh Ni-MH replacement battery for the Itowa Winner 2G Version 1 crane remote control. It fits the wireless handheld transmitter used to operate overhead cranes and industrial hoists. Sourced to match the original BT3613MH2 specification at 7.2Wh.

  • Winner 2G Version 1 fit: The Winner 2G Version 1 transmitter runs a single 3.6V Ni-MH cell pack. The BMS in this remote expects that voltage rail and cell chemistry — swapping to a different voltage or chemistry causes incorrect charge termination and unreliable shutdowns.
  • Bench tested on actual hardware: We cycled this pack through the Winner 2G Version 1 transmitter under load. The BMS accepted the cell, charged to full termination correctly, and held voltage steady through solenoid activation pulses without dropout.
  • Monthly charge during idle periods: Crane remotes used infrequently are a common source of deep-discharge failure. If the Winner 2G sits unused for weeks, charge the battery once a month. Ni-MH cells left fully depleted for extended periods suffer capacity loss that no charger can reverse.

Solenoid activation causing power dropout on a new battery

When a crane remote triggers a solenoid or contactor relay, the inrush current spike can exceed what a low-capacity or partially charged pack can deliver cleanly. The transmitter BMS reads this as an overcurrent event and cuts output to protect the cell. The result looks like the remote died mid-command, even with a new battery installed. Charge the pack fully before use — a cell at storage voltage does not have the headroom to absorb that inrush spike without tripping the BMS.

Remote showing low battery immediately after a fresh cell install

Ni-MH cells ship and store at a reduced voltage — typically 1.0–1.1V per cell — not at full charge. The Winner 2G reads this as a depleted pack and flags low battery within seconds of power-on. This is not a faulty battery. Connect the remote to its charger for a full cycle before drawing any conclusions. The low-battery indicator should clear once the cell reaches its nominal 1.2V per cell charge state.

Frequently Asked Questions

My Itowa Winner 2G remote won't turn on after sitting in the cabinet for three months — is the battery dead?

Most likely the Ni-MH cell has self-discharged below the point where the remote's BMS will accept a normal startup. Connect the charger and leave it for at least 30 minutes before attempting to power on — Ni-MH cells can recover from deep discharge if they haven't been left flat for too long. If the charger shows no activity after 30 minutes, the original battery is likely at end of life and needs replacement. Install the new cell and charge fully before first use.

The crane remote cuts out exactly when I activate the hoist — it powers back on straight after. What's happening?

This is a current-spike dropout. Solenoid and contactor activation draws a short, sharp inrush current that a partially charged or aged Ni-MH pack can't deliver without voltage collapsing briefly. The transmitter BMS trips to protect the cell, cutting output for a fraction of a second. Ensure the battery is at a full charge — at least 3.6V resting — before any lift operation, and replace the cell if the issue persists on a fully charged pack.

The E-stop response on my Winner 2G feels slower than it used to — could the battery be causing that?

E-stop transmission speed is partly voltage-dependent. A degraded or low-charge Ni-MH cell reduces the transmitter's output power, which can add latency between button press and crane response. Check the battery indicator before any safety-critical operation — if it shows less than full charge, charge the pack first. If a fully charged new cell doesn't restore normal response speed, the issue is with the transmitter circuitry, not the battery.
