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.

GENEKO SuperCash — 7.4V Li-ion Replacement Battery (INR18650 2S1P)
This is a 7.4V, 2600mAh Li-ion replacement battery for the GENEKO SuperCash point-of-sale terminal. It fits the backup battery bay and keeps the register operational when mains power drops. The INR18650 2S1P configuration matches the original cell arrangement and connector layout.
- SuperCash backup bay fit: The SuperCash uses a 2S1P 18650 pack to supply the backup rail. This replacement matches that voltage and cell count, so the register's trickle charger and BMS handshake with the pack as expected.
- Bench tested on actual hardware: We cycled this pack through the SuperCash's charge and discharge sequence. The BMS held cutoff correctly at both the low-voltage floor and the 8.4V charge ceiling with no thermal events.
- First-install charge procedure: After fitting this battery, leave the register running on mains power for 12 hours before testing backup. The SuperCash charges the pack through a trickle circuit — a partial charge will not sustain the terminal through a real outage.

PLU data and price tables on the SuperCash are held in volatile RAM. That RAM depends on the backup battery to retain its contents the moment mains power drops. If the new battery was not fully charged through the register's trickle charger before the outage, the voltage sags below the RAM retention threshold within seconds. The fix is straightforward — run the terminal on mains for at least 12 hours after fitting the new pack before exposing it to a real or simulated power loss.

The SuperCash display and printer draw separate load rails during a power event. A partially discharged or degraded pack can hold enough voltage to pass the BMS check during normal operation but sag immediately when the display and any pending print job pull current simultaneously. Check the pack voltage at the terminal contacts — it should read between 7.2V and 8.4V under no load. If it reads below 7.0V, the pack has not completed its trickle charge cycle or has a depleted cell; return it to a full 12-hour mains charge before retesting.

Frequently Asked Questions
My SuperCash keeps losing its programmed prices every time the power goes out, even after fitting a new battery — what's happening?
PLU data sits in volatile RAM that depends entirely on the backup battery the instant mains drops. If the pack wasn't fully charged through the register's trickle circuit before the outage, it can't hold that RAM alive. Run the register on mains for 12 hours straight after installing the new battery before testing it against a power loss. After that full charge, the pack should read between 7.2V and 8.4V at the terminals.
The display goes blank the moment the power cuts, but the register comes back fine when mains returns — is that the battery or something else?
The display and any active print job pull simultaneous current the moment mains fails, and that combined load causes a partially charged pack to sag below the display's minimum operating voltage immediately. The register recovers on mains return because the battery never actually failed — it just couldn't handle the peak draw. Measure the pack voltage before the next outage; anything below 7.2V means the trickle charge cycle is incomplete. Keep the terminal on mains for 12 hours after fitting the battery, then retest.
The backup battery is only a few months old but it's already not holding the register up during outages — why is it draining so fast?
Continuous trickle charging at a slightly elevated voltage stresses Li-ion cells and accelerates capacity loss over months. If the register's charger circuit is outputting above 8.4V, the pack degrades faster than normal cycling would cause. Check the charger output voltage at the battery contacts with a multimeter — it should sit between 8.2V and 8.4V at full charge. If it reads higher, the issue is in the register's charging circuit, not the pack itself.
