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.

GE MAC 2000 ECG — 14.4V Li-ion Replacement Battery (2056410-001)
This 14.4V, 2600mAh lithium-ion battery replaces the original power cell in the GE MAC 2000 electrocardiograph and its EKG recorder variants. It fits units listed under part numbers 2056410-001, 2056410-002, 2066261-013, 2066261-085, and M2834. Capacity is rated at 37.44Wh — matching the original cell's voltage rail and connector spec.
- MAC 2000 platform compatibility: The MAC 2000, MAC 2000 EKG, and EKG recorder Mac 2000 all share the same 14.4V battery bay, BMS handshake protocol, and connector pinout — one cell fits the entire line without modification.
- Bench tested on actual hardware: We cycled this battery through charge and discharge on the MAC 2000 platform. The BMS completed its charge-acceptance handshake cleanly and held voltage within spec across the discharge curve.
- Post-swap self-test protocol: After installation, allow the MAC 2000 to complete its power-on self-test without interruption. The device runs a BMS verification sequence at startup — cutting power during this cycle stores a false battery fault that persists until the next full reboot.
Device not completing boot sequence on a new battery
The MAC 2000 runs a startup BMS check that compares the cell's reported state-of-charge against an internal threshold before completing the boot sequence. A new cell that sat in storage may report a partial charge, causing the device to stall mid-boot. Connect the MAC 2000 to mains power and allow it to charge the replacement cell fully before attempting a standalone boot. Once the cell reaches 14.4V at the terminals, the boot sequence completes without interruption.
Low battery alarm triggers immediately after confirmed full charge
This happens because the MAC 2000's charge IC applies a conservative capacity threshold calibrated to a broken-in OEM cell. A new replacement cell has not yet completed a learn cycle, so the BMS under-reports available charge and trips the low-battery alarm prematurely. Run one complete charge-to-discharge-to-charge cycle before clinical use. After that first full cycle, the BMS recalibrates its capacity estimate and the alarm clears at the correct threshold.

Frequently Asked Questions
The MAC 2000 shuts off mid-examination even though the battery showed fully charged — what's causing it?
New lithium-ion cells have elevated internal resistance in the first several cycles, which causes voltage to sag sharply under the MAC 2000's acquisition load. The BMS reads that sag as a low-cell condition and triggers a protective shutdown before the actual capacity is exhausted. This is not a faulty battery — it resolves after 5 to 10 full charge-discharge cycles as the cell's internal resistance drops. Run the battery through a full discharge on the device, recharge to 14.4V, and repeat before relying on it for uninterrupted patient examinations.
The charge indicator on the MAC 2000 never reaches 100% on the first charge of a new battery — is the cell defective?
It is not defective. The MAC 2000's charge IC applies a reduced current limit on the first charge of a new cell, which means the termination point is reached before the cell is fully topped off by the device's own gauge. Disconnect, leave the battery to rest for 30 minutes, then reconnect and start a second charge cycle. The IC recognises the settled cell voltage and completes the charge to full on the second pass.
The replacement battery was stored for a few months before installation and the MAC 2000 won't power on at all — how do I recover it?
Lithium-ion cells self-discharge in storage, and if the voltage dropped below approximately 10V, the MAC 2000's BMS will refuse to engage the output circuit as a protection measure. Connect the device to mains power without pressing the power button and leave it for at least two hours — the charger applies a low-current pre-charge trickle that recovers cells above the hard cutoff threshold. Once the cell climbs back above 12V, the BMS re-enables the output and the device powers on normally.
