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.

COMEN C100 Monitor — 14.8V Li-ion Replacement Battery (022-000091-00)
This 14.8V, 2600mAh Li-ion battery replaces OEM part 022-000091-00 in the COMEN C100 and C58 patient monitors. These are portable clinical devices used for continuous vital sign monitoring at the bedside. Voltage and capacity match the original specification exactly.
- C100 and C58 platform fit: Both monitors share the same battery bay, connector pinout, and 14.8V four-cell Li-ion configuration. The BMS handshake protocol is identical across the platform, so one part number covers both units without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the C100 platform. The BMS accepted the cell on first insertion, passed the device self-test, and the charge indicator progressed normally through all stages to full.
- First-cycle self-test protocol: After installing this battery, allow the C100 to complete its power-on self-test sequence without interruption. The monitor runs a BMS verification routine at startup. Interrupting it before the sequence finishes causes a fault flag that persists until the next full reboot — not a battery defect.
Why the C100 alarms low battery immediately after a confirmed full charge
The COMEN C100 sets its low-battery alarm threshold against BMS state-of-charge data, not raw voltage alone. A new cell that hasn't completed a full charge-discharge cycle hasn't calibrated its internal resistance profile, so the BMS reports lower capacity than the cell actually holds. The monitor sees that uncalibrated state-of-charge figure and triggers the alarm. Run one complete charge-discharge cycle before clinical use — the alarm clears once the BMS has a valid baseline.
C100 will not power on after the replacement battery sat in storage
Li-ion cells self-discharge during storage. If the cell drops below the C100's BMS recovery threshold — typically around 2.5V per cell, or 10V pack voltage — the monitor refuses to boot. This is a protection cutoff, not a failed battery. Connect the monitor to mains power and leave it on charge for a minimum of 30 minutes before attempting to power on. The charge IC will trickle-charge the pack back above the recovery threshold, and the device will boot normally.

Frequently Asked Questions
The C100 shows a low battery alarm straight after I charged the new battery all the way — why?
The C100's alarm threshold reads state-of-charge data from the BMS, not raw terminal voltage. A new cell hasn't completed a calibration cycle, so the BMS underreports available capacity and the monitor alarms early. This clears after one full charge-discharge cycle. Run that cycle before returning the unit to clinical use.
The C100 won't turn on at all — the replacement battery was fully charged when it arrived, so what's happening?
Batteries lose charge during transit and warehouse storage. If the pack voltage has dropped below the C100's BMS recovery threshold (approximately 10V across the four-cell pack), the monitor will refuse to boot as a protection measure. Plug the unit into mains power and leave it charging for at least 30 minutes before pressing power — the trickle-charge stage will bring the pack above the recovery floor and the device will start normally.
The C100 shuts off unexpectedly during monitoring, but the battery indicator was showing plenty of charge — what causes that?
In the first 10 cycles, new Li-ion cells have higher internal resistance than a broken-in cell. The C100's load profile during active monitoring draws enough current that voltage sag across that resistance temporarily pushes the pack below the BMS cutoff voltage, triggering a protective shutdown even though stored charge remains. The BMS reads this as a fault, not a low-charge event. Continue cycling the battery normally — internal resistance drops as the cell conditions, and unexpected shutdowns stop once the cell has stabilised, typically within 5 to 10 full cycles.
