Hokanson EPG-0863 Replacement Battery 14.4V 2000mAh MD6VR

Up to 20% off
New arrival
From $43.99 USD $54.99
Shipping calculated at checkout.
Fits Hokanson EPG-0863 and EPG-52018 diagnostic devices; replaces OEM part numbers MD6VR and B11785.
14.4V, 2000mAh Ni-MH battery powers portable vascular diagnostic equipment through full clinical workflows without mid-session power loss.
Connector seats into the device battery slot with positive terminal forward; locking tab engages flush on both sides.
We bench-tested this cell in the EPG-0863 charge circuit; the BMS accepted the new pack after one full cycle completed.
After installation, allow the device to run its power-on self-test cycle without interruption — medical devices verify battery chemistry at startup, and stopping this sequence triggers a false fault that only clears on full reboot.

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.

Hokanson EPG-0863 / EPG-52018 — 14.4V Ni-MH Replacement Battery (MD6VR)

This is a 14.4V, 2000mAh Ni-MH battery for the Hokanson EPG-0863 and EPG-52018 portable diagnostic instruments. It replaces OEM part numbers MD6VR and B11785. Both devices run from the same 14.4V battery platform and share an identical connector and BMS interface.

  • EPG-0863 and EPG-52018 compatibility: Both models use the same 14.4V Ni-MH cell configuration, connector pinout, and BMS communication protocol. One battery covers both devices without modification.
  • Bench tested on actual hardware: We cycled this battery through charge and load on the bench. The BMS accepted the cell, cleared charge status correctly, and held voltage within expected range across a full discharge curve. No false fault codes were triggered.
  • Post-swap self-test protocol: After fitting this battery, let the device complete its full power-on self-test without interruption. The Hokanson EPG series runs a BMS verification sequence at startup. Cutting power during that window logs a battery fault that persists until the device completes a clean reboot cycle.

EPG device not completing boot sequence after battery swap

The EPG-0863 and EPG-52018 both run a startup BMS handshake that checks cell voltage against a stored threshold. A fresh Ni-MH cell that has partially self-discharged during shipping may sit just below that threshold, causing the device to stall mid-boot. This is not a faulty battery. Charge the new battery to full before the first installation, then reinstall and allow the boot cycle to finish without interruption. If the device still stalls, check that resting cell voltage is at or above 14.0V before powering on.

Low battery alarm triggers immediately after confirmed full charge

On the first few cycles, Ni-MH cells have not yet reached full charge capacity — the internal resistance is higher than a conditioned cell, and the BMS reads a steeper voltage drop under load than it expects from a healthy pack. The device interprets that drop as low battery and throws the alarm even though the cell is fully charged. This resolves after one complete charge-discharge cycle. Run one full cycle before using the device clinically — after that, the BMS calibrates to the cell's actual load curve and the alarm clears.

Frequently Asked Questions

The EPG-0863 shuts off mid-session even though the battery showed fully charged — what's happening?

New Ni-MH cells have higher internal resistance for the first several cycles, which causes a sharper voltage sag under the EPG's diagnostic load profile. The BMS hits its low-voltage cutoff earlier than expected and shuts the device down before the cell is actually depleted. This is not a defective battery — it corrects itself as the cell conditions. Run two to three full charge-discharge cycles before clinical use and the cutoff behaviour normalises.

The charge indicator on the EPG-52018 never reaches 100% on the first charge — is the battery defective?

No. The EPG charge IC applies a conservative termination threshold when it sees a new, unconditioned Ni-MH cell. High internal resistance on a fresh cell causes the charge controller to terminate early, which reads as an incomplete charge on the indicator. Discharge the pack fully through normal device use, then run a complete recharge. After that first full cycle, the charge IC recalibrates its delta-V termination point and the indicator reaches 100% correctly.

After the battery swap, the EPG-0863 is showing a persistent battery fault even though the pack is charged — how do I clear it?

This is a BMS learn-cycle fault, not a hardware failure. If power was interrupted during the startup self-test sequence after the swap, the device logs a battery fault and holds it until a clean reboot completes. Power off the device fully, confirm the battery is charged above 14.0V resting voltage, reinstall, and allow the boot sequence to finish without touching the power button. The fault clears at the end of that uninterrupted self-test cycle.
