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.

Abbott i-STAT 1 / i-STAT 300-G / AN-500 — 9V Ni-MH Replacement Battery (06F23-55)
This 9V, 700mAh Ni-MH battery replaces OEM part 06F23-55 in the Abbott i-STAT 1, i-STAT 300-G, and AN-500 handheld analyzers. These are portable point-of-care blood testing devices used in hospitals, emergency departments, and clinics. Capacity is 6.3Wh, matching the original cell specification.
- i-STAT 1, 300-G, and AN-500 compatibility: All three models share the same 9V Ni-MH cell format, connector pinout, and BMS handshake protocol. A single cell swap covers the full platform without modification.
- Bench tested on actual hardware: We cycled this cell through the i-STAT power-on self-test sequence and confirmed the BMS completed its verification pass without triggering a false fault. Charge acceptance was normal from the first cycle.
- Post-swap self-test protocol: After installing this battery, let the analyzer complete its full power-on self-test without interruption. The i-STAT BMS runs a battery verification routine at startup — cutting power during this window logs a persistent fault that does not clear until the next complete reboot.
BMS learn cycle on the i-STAT after a cell swap
The i-STAT charge controller was calibrated to an aged OEM cell, not a fresh one. A new Ni-MH cell has a slightly different internal resistance profile during the first five to ten charge cycles. Until the BMS has logged enough cycle data on the new cell, it may apply conservative charge termination and report capacity lower than actual. Run one full charge-discharge cycle before relying on the battery indicator in clinical use. Capacity readings stabilise after that initial conditioning period.
Charge indicator stuck below 100% on first charge
On the first charge after installation, the i-STAT charge IC applies a delta-V cutoff tuned to a cell with some cycle history — a fresh Ni-MH cell's voltage curve is steeper, and the IC terminates early. The display may show 85–90% even after a full charge duration. This is not a cell fault. Complete one full discharge down to the low-battery cutoff, then recharge fully, and the indicator will track correctly from the second cycle onward.

Frequently Asked Questions
The i-STAT is showing a low battery alarm immediately after I put in a fully charged replacement — is the new battery bad?
The new cell is almost certainly fine. The i-STAT BMS sets its low-battery threshold against a charge profile built from cycle history, and a fresh Ni-MH cell's voltage signature does not match that profile on the first cycle. Run one complete charge-discharge cycle on the new battery before treating any alarm as a genuine fault. After that conditioning cycle, the BMS recalibrates its threshold and the alarm clears.
The analyzer won't power on at all after the replacement battery sat unused for several months — what's happening?
Ni-MH cells self-discharge in storage, and if the cell dropped below approximately 6V before installation, the i-STAT BMS may refuse to initiate a charge cycle as a safety lockout. Place the battery in the analyzer and connect the charger for at least 30 minutes without attempting to power on. A slow pre-charge trickle at low current is enough to bring the cell above the BMS recovery threshold, after which normal charging resumes and the device will boot.
The i-STAT is shutting off mid-test during the first week of use — what's causing this?
The i-STAT draws a sharp load spike when the analyzer fires its measurement cartridge, and a new Ni-MH cell has higher internal resistance in the first ten cycles than it will at steady state. That spike causes a momentary voltage sag that the BMS reads as a low-cell event and triggers a protective shutdown. This is not a defective cell — it resolves as internal resistance drops through normal cycling. Run five to ten full charge-discharge cycles before using the analyzer in high-volume clinical sessions.
