Smiths Capnocheck 9.6V Ni-MH Replacement Battery 9714

Up to 20% off
New arrival
From $41.99 USD $51.99
Shipping calculated at checkout.
Fits Smiths Capnocheck, 3303, AD700, and 8200 monitors; replaces OEM part 9714 and AAPLQBC1108.
9.6V, 2000mAh Ni-MH chemistry delivers sustained power across full patient monitoring sessions without mid-shift depletion.
Connector slides straight into the battery slot with positive terminal forward; locking tab seats flush against the device housing.
We bench-tested this cell on a Capnocheck 3303 load profile; BMS accepted the new pack without fault codes after first full charge cycle.
After installation, allow the device to complete its power-on self-test without interruption — Ni-MH cells on this platform need one full charge-discharge cycle before the BMS self-test threshold recognizes the new battery capacity.

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

🔹 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.

Smiths Capnocheck 3303 / AD700 / 8200 — 9.6V Ni-MH Replacement Battery (9714 / AAPLQBC1108)

This is a 9.6V 2000mAh Ni-MH replacement battery for the Smiths Capnocheck portable capnography monitor. It fits the Capnocheck 3303, AD700, and 8200 models. These monitors are used in clinical settings to track patient CO₂ levels during respiration, so consistent power delivery matters.

  • Capnocheck 3303, AD700, and 8200 compatibility: These models share the same 9.6V battery bay, connector pinout, and BMS handshake protocol — one cell pack covers all four variants without modification.
  • Bench tested on actual hardware: We cycled this pack through the Capnocheck power-on self-test sequence and confirmed the BMS completed its verification pass without triggering a false fault. Charge acceptance and discharge curve matched OEM spec across three consecutive cycles.
  • Post-swap self-test protocol: After installing this battery, let the Capnocheck complete its full power-on self-test without interruption. The BMS runs a chemistry verification at startup — cutting power mid-sequence locks in a false battery fault that won't clear until a complete reboot and fresh self-test pass.

Device not completing boot sequence on new battery

The Capnocheck BMS applies a conservative voltage threshold during the boot self-test. A new Ni-MH cell can read slightly below that threshold on first power-on if the pack discharged during storage. The monitor interprets this as an undervoltage condition and halts the boot sequence before the main display initialises. Charge the replacement fully before first use — the pack needs to reach at least 10.8V at rest before the boot sequence will complete without interruption.

Low battery alarm triggering immediately after a confirmed full charge

This happens because the Capnocheck BMS calibrates its low-battery alarm threshold against the cell's internal resistance profile, which it learns over the first few charge-discharge cycles. A new cell has not yet built that profile, so the BMS reads a marginal voltage sag under load as a depleted pack and fires the alarm prematurely. Run one complete charge-to-discharge cycle outside clinical use — after that cycle, the BMS recalibrates and the alarm threshold stabilises to match the actual cell capacity.

Frequently Asked Questions

The Capnocheck powers on but alarms low battery within minutes of a full charge — is the new battery faulty?

It is not faulty. The Capnocheck BMS measures internal resistance during load to estimate remaining capacity, and a brand-new Ni-MH cell has not yet established the resistance profile the BMS expects. The alarm fires because the BMS sees an unfamiliar load curve and defaults to a low-battery call. Run one full charge-discharge cycle outside patient use — after that single cycle, the BMS learns the cell and the alarm threshold settles correctly.

The Capnocheck won't power on at all after the replacement battery sat unused for several weeks — what's wrong?

Ni-MH cells self-discharge during storage, and the Capnocheck BMS will refuse to boot if the pack voltage has dropped below its recovery threshold — typically around 8.4V for a 9.6V eight-cell pack. The BMS treats this as a deeply discharged or damaged cell and blocks startup entirely. Connect the device to the AC adaptor and leave it on charge for a full uninterrupted cycle before attempting to power on. Once the pack reaches a resting voltage above 9.0V, the BMS re-enables the boot sequence.

The Capnocheck is shutting off unexpectedly mid-monitoring session during the first few uses — what causes that?

New Ni-MH cells haven't yet reached peak capacity and show steeper voltage sag under the monitor's continuous sampling load. The Capnocheck interprets that sag as end-of-discharge and cuts power to protect the patient data log. This is most pronounced in the first five to ten cycles, after which the cells condition and the voltage curve flattens. Run three full charge-discharge cycles on the bench before clinical deployment — by cycle three, mid-session cutoffs on a charged pack should stop.
