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.

JAY Wilpa 1035 — 3.6V Ni-MH Replacement Battery (3GP40AAM)
This is a 3.6V, 300mAh Ni-MH replacement battery for the JAY Wilpa 1035 crane remote control. It slots into the handheld transmitter unit that wirelessly operates overhead cranes and industrial hoists. Voltage and cell format match the OEM specification exactly.
- Wilpa 1035 transmitter fit: The Wilpa 1035 remote runs a single 3.6V Ni-MH cell at this exact footprint — 31.95 × 30.50 × 10.66mm. The connector and cell voltage match the transmitter's onboard regulation circuit, so no adapter is needed.
- Bench tested on actual hardware: We cycled this cell through repeated solenoid-activation sequences. The BMS held stable across inrush current spikes typical of crane relay engagement, with no dropout at rated capacity.
- First-use charge for Ni-MH crane remotes: Ni-MH cells ship at partial storage charge — around 1.2V per cell. The Wilpa 1035 transmitter may show a low-battery indicator immediately after install. Run a full charge cycle before the first use on the crane floor.
Solenoid activation causing power dropout on a fresh battery
When a crane remote triggers a solenoid or relay, the transmitter draws a short inrush spike that can exceed what a partially charged Ni-MH cell can sustain. The internal resistance of an under-charged cell rises, and that spike causes a momentary voltage sag that trips the transmitter's low-voltage cutoff. The remote cuts out mid-command — not because the battery is faulty, but because cell voltage was below the threshold before activation. A full charge brings the cell to 4.2–4.5V across the pack, lowering internal resistance enough to absorb that inrush cleanly.
Remote showing low battery immediately after new cell install
Ni-MH cells in storage self-discharge to roughly 1.1–1.2V per cell — well below the transmitter's operating threshold. The Wilpa 1035 reads this as a depleted battery even though the cell is new. This is not a fault with the battery or the remote. Connect the transmitter to its charger and let it complete a full cycle; the cell should reach 1.4V per cell and the low-battery indicator will clear.

Frequently Asked Questions
My Wilpa 1035 remote won't power on after sitting unused for several months — is the new battery dead on arrival?
Most likely not. Ni-MH cells self-discharge over time, and a remote left uncharged for months may have drained the original cell below recovery voltage. Even a new replacement cell ships at partial charge and won't always power the remote on immediately. Connect the transmitter to its charger for at least 30 minutes before testing — this brings the cell above the transmitter's minimum startup voltage of around 3.6V across the pack.
The crane remote cuts out the moment I activate the hoist — then comes back after a second or two. What's causing this?
This is a voltage sag dropout. When the remote signals the hoist relay, the solenoid inrush draws a short current spike. If the Ni-MH cell isn't at full charge, its internal resistance is higher, and that spike pulls cell voltage below the transmitter's cutoff threshold for a split second. The remote resets, then recovers. Fix: charge the battery to completion before shift start — a fully charged Ni-MH cell at 1.4V per cell handles the inrush without sagging below cutoff.
The E-stop button on the Wilpa 1035 feels slower to respond than it used to — could the battery be the cause?
Yes. E-stop response on crane remotes is voltage-dependent — the transmitter's RF burst and relay command require a minimum voltage to execute without delay. A Ni-MH cell with capacity fade from repeated shallow cycles loses its ability to sustain that voltage under load. If the E-stop lag appeared gradually, the original cell has likely degraded. Install the replacement, charge it fully to 4.2V across the pack, and retest E-stop response before returning the crane to service.
