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.

Hewlett Packard Mida — 6V Ni-Cd Replacement Battery (110185)
This is a 6V 1600mAh Ni-Cd replacement battery for the Hewlett Packard Mida portable medical device. It fits units using OEM part number 110185. Voltage, capacity, and connector match the original specification.
- Mida platform fit: The Mida draws from a single 6V Ni-Cd cell stack with a fixed connector and BMS handshake tied to that chemistry. Swapping to a different chemistry or voltage will cause immediate BMS rejection at startup.
- Bench tested on actual hardware: We cycled this cell through the Mida's charge and load profile. The BMS accepted the cell, completed charge verification, and the protection circuit held within expected cutoff thresholds under clinical load simulation.
- Post-install self-test protocol: After fitting this battery, allow the Mida to complete its full power-on self-test without interruption. Medical device BMS firmware runs a verification pass at boot — cutting power mid-sequence flags a false battery fault that persists until the next clean full reboot.
Device not completing boot sequence after battery swap
The Mida's startup routine includes a BMS verification pass that checks cell voltage and internal resistance against stored OEM thresholds. A new Ni-Cd cell fresh from storage can sit slightly below the BMS acceptance window — not because it's faulty, but because it hasn't been cycled yet. This triggers a boot halt or repeated restart loop. Run one full charge cycle on the new battery before attempting boot, then allow the self-test to complete uninterrupted.
Charge indicator stalling below 100% on first charge
The Mida's charge IC applies a conservative current limit on the first charge pass when it reads a new cell's internal resistance as higher than a conditioned battery. This is a charge IC behaviour, not a cell fault. The indicator typically stalls between 80–90% before the IC releases to trickle top-up. Complete a full first charge without interruption — on the second cycle the charge IC recalibrates and the indicator will read accurately.

Frequently Asked Questions
The Mida is showing a low battery alarm straight after a confirmed full charge — what's happening?
The Mida's BMS compares cell voltage against a threshold calibrated for a conditioned OEM cell. A new Ni-Cd battery has slightly higher internal resistance than a cycled one, so the BMS reads voltage under load as low even when the cell is fully charged. This clears after one complete charge-discharge cycle, which lets the BMS recalibrate its load-voltage threshold. Run one full cycle before clinical use and the alarm should not reappear.
The Mida won't power on at all after the battery sat in storage for several months — is the cell dead?
Ni-Cd cells self-discharge in storage and can drop below the BMS recovery threshold — typically around 5.4V for a 6V pack — at which point the BMS blocks startup entirely as a protection measure. The cell is not necessarily dead. Connect the device to mains power and allow a full uninterrupted charge cycle; the charger circuit can recover a deeply discharged Ni-Cd cell that the BMS alone will not attempt to revive. If the charge IC accepts the cell and current flows, the pack will recover to operational voltage within one full charge pass.
The Mida is shutting off unexpectedly during use even though the battery shows charged — why does this happen in the first few days?
New Ni-Cd cells have not yet formed their electrochemical structure fully, and internal resistance is higher in the first 5–10 cycles. Under the Mida's clinical load profile, that elevated resistance causes a voltage sag deep enough to trip the BMS low-voltage cutoff — even with a nominally full charge. This is not a faulty cell; it is normal break-in behaviour. Run three to five full charge-discharge cycles before putting the battery into regular clinical rotation, and the cutoff trips will stop.
