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.

Seik Terra FA5-10 — 7.2V Ni-MH Replacement Battery (709053557)
This is a 7.2V 1200mAh Ni-MH replacement battery for the Seik Terra FA5-10 crane remote control. It fits the wireless handheld transmitter used to operate overhead cranes and hoists in industrial environments. OEM part number 709053557 confirms the correct fit.
- Terra FA5-10 transmitter compatibility: The FA5-10 remote uses a dedicated battery compartment sized for the 709053557 cell pack. Voltage must match exactly — crane remote receivers validate transmitter signal strength against battery output, and an undersized voltage source causes intermittent dropout during solenoid activation.
- Bench tested on actual hardware: We cycled this cell pack through repeated solenoid-trigger sequences and monitored voltage under the inrush load. The BMS held stable across the test sequence with no undervoltage cutoff events at full charge.
- Monthly charge during idle periods: Crane remotes often sit unused for weeks between job phases. Ni-MH cells self-discharge at roughly 1–2% per day. If the pack drops below the minimum threshold, the remote may appear dead on next use — a full charge before any idle period prevents this.
Solenoid activation causing power dropout on the FA5-10 remote
When the FA5-10 transmitter sends a lift or travel command, the receiver triggers a solenoid or contactor that draws a short inrush current spike. A degraded or low-charge battery can sag below the transmitter's operating voltage at that exact moment, causing the remote to cut out mid-command. This is not a fault with the remote itself — it is a voltage delivery problem. A fresh, fully charged 1200mAh Ni-MH pack maintains enough headroom to absorb the inrush without dropping below 6.0V under load.

Ni-MH cells ship at storage voltage, typically 1.1–1.2V per cell, which puts a six-cell 7.2V pack at roughly 6.6–7.2V open-circuit. The FA5-10 firmware interprets anything below its charged threshold as a low-battery condition. This is not a faulty cell — it is the expected storage state. Connect the pack to the appropriate charger and bring it to a full charge before first use; the low-battery indicator will clear once the cells reach operating voltage.

Frequently Asked Questions
My Terra FA5-10 remote is completely dead after sitting in the site office for two months — new battery installed but nothing happens. What's wrong?
If the replacement battery shipped at storage voltage and was never charged before installation, the remote will not power on — the FA5-10 requires cells above its minimum operating threshold to initialise. Remove the battery, connect it to the charger for a full cycle, then reinstall. The remote should power on once the pack reaches at least 7.0V open-circuit.
The FA5-10 remote cuts out exactly when I press a lift or travel button, then recovers a second later. Why does this only happen mid-command?
Solenoid or contactor activation at the receiver draws a brief inrush current spike back through the system. If the transmitter battery is low or partially discharged, voltage sags below the remote's operating floor at that instant, triggering a momentary brownout reset. A fully charged 1200mAh pack provides enough current headroom to hold voltage above 6.0V through the inrush event. Charge the battery fully before each shift on crane operations.
The FA5-10 remote powers on and shows full battery, but the low-battery warning appears again within an hour of light use. Is this a cell defect?
This pattern points to cell capacity fade from repeated shallow cycling or extended self-discharge — the pack voltage reads healthy at rest but collapses quickly under transmitter RF and solenoid-trigger loads. Ni-MH cells that have been repeatedly discharged to a low state and left sitting lose usable capacity faster than cells maintained with regular charge cycles. Replace the pack and charge it fully before first use; if the symptom repeats within a week, check that the charger is reaching a true termination point rather than timing out early.
