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.

Ikusi TM63 / TM64 02 — 7.2V Ni-MH Replacement Battery (BT12)
This is a 7.2V, 2000mAh Ni-MH replacement for the Ikusi BT12 battery pack. It fits the TM63 and TM64 02 wireless crane remote controllers used in industrial lifting and hoist operations. Voltage and cell count match the original specification exactly.
- TM63 and TM64 02 compatibility: Both remotes run the same 7.2V six-cell Ni-MH architecture and share the BT12 connector footprint and housing dimensions. A single cell pack covers both units without modification.
- Bench tested on actual hardware: We cycled this pack through repeated solenoid-activation sequences on a TM63 test rig. The BMS held stable through inrush current spikes at relay activation with no mid-operation dropout.
- First-use charge on crane remotes: Ni-MH cells ship at partial storage voltage. On a crane remote, operating at low cell voltage during solenoid activation can trigger a premature low-battery cutoff. Charge the pack fully before the first use — put it on the Ikusi charger until the charge light confirms completion.
Solenoid activation causing power dropout on a fresh BT12 pack
When a crane remote fires a solenoid or relay, inrush current spikes sharply for a fraction of a second. If the battery is at partial charge, cell voltage can dip below the BMS cutoff threshold during that spike, and the remote drops out mid-command. This is not a faulty battery — it is a voltage-sag event on an under-charged pack. Ni-MH cells at storage voltage simply cannot sustain the instantaneous current draw. A full charge before field use eliminates this entirely.
Remote showing low-battery warning immediately after fitting a new pack
A new Ni-MH pack sitting in storage self-discharges slowly and arrives well below its rated voltage. The TM63 reads cell voltage at power-on, and if it sees less than approximately 6.0V across the pack, it flags low battery straight away. This is not a defective cell — it is a storage-state reading. Place the pack on the Ikusi charger for a full charge cycle before diagnosing a fault. After a complete charge the voltage should return to 7.2V and the warning clears.

Frequently Asked Questions
My TM63 sat unused for three months and now it won't power on at all — is the battery dead?
Likely not dead, but possibly in deep-discharge lockout. Ni-MH cells left discharged for months can drop low enough that the remote's power circuit won't initialise. Connect the battery to the Ikusi charger and leave it for at least 30 minutes before attempting to power on — a trickle pre-charge is often enough to bring the pack back above the threshold. If the charger light never moves to a charge state, the cells have likely gone below recovery voltage and a replacement pack is needed.
The TM63 cuts out the moment I activate a hoist function, then recovers a few seconds later — what's causing this?
This is a voltage-sag dropout at the moment of solenoid inrush. When the remote fires a relay command, current demand spikes instantly, and a partially charged or aged pack can't hold voltage above the BMS cutoff through that spike. The remote shuts down, the inrush ends, voltage recovers, and it restarts. Check that the pack is at full charge — 7.2V resting — before use. If dropouts continue on a fully charged new pack, verify the charger is actually completing its cycle and not stopping early.
How often should I charge the BT12 battery if the crane remote only gets used a few times a month?
Ni-MH cells self-discharge at roughly 1–2% per day at room temperature, so a pack left sitting between infrequent jobs will be significantly depleted by the time it's needed. Charge the battery once every four weeks during idle periods, even if the remote hasn't been used. This keeps cell voltage above the level where deep-discharge damage begins and ensures the pack is ready for immediate use when a lift is required. Store the charged remote away from heat sources, as elevated temperatures accelerate self-discharge in Ni-MH chemistry.
