Horizon KRONOS 200 Replacement Battery HKB10 7.4V 2200mAh

Up to 20% off

From $33.99 USD $41.99
Shipping calculated at checkout.
Fits Horizon KRONOS 200 surveying instruments; replaces OEM part number HKB10.
7.4V, 2200mAh lithium-ion cell delivers sustained power through full measurement cycles without mid-session dropout.
Connector seats into the battery slot with a positive contact tab on the upper edge; locking tab secures pack flush against the instrument body.
We bench tested this pack under sustained probe sensor load at room temperature; the BMS held voltage stable through 90-minute measurement logging without cutoff events.
After installation, run a full calibration cycle through the KRONOS 200 menu before field work — the instrument maps battery voltage during calibration, and skipping this step triggers premature low-battery warnings on the first measurement session.

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

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.

Horizon KRONOS 200 — 7.4V Li-ion Replacement Battery (HKB10)

This is a 7.4V, 2200mAh Li-ion replacement battery for the Horizon KRONOS 200 surveying instrument. It replaces OEM part number HKB10 and fits directly into the KRONOS 200 battery bay. Capacity is 2200mAh (16.28Wh), matching the original specification.

  • KRONOS 200 compatibility: The KRONOS 200 uses a 7.4V dual-cell Li-ion pack with a specific connector and BMS handshake. This replacement matches that voltage rail and communication protocol, so the instrument's power management system reads the pack correctly without throwing a battery fault.
  • Bench tested on actual hardware: We cycled this pack through the KRONOS 200's boot sequence and active measurement states. The BMS held stable under the sensor initialisation current spike and did not trip during sustained logging draws.
  • First-deployment calibration: After installing this battery, run a full calibration cycle through the KRONOS 200 instrument menu before heading into the field. The instrument maps battery state during that process — skip it, and the low-battery indicator will trigger early on your first measurement session.

BMS lockout after the KRONOS 200 sat unused in a carry case for months

Li-ion cells self-discharge over time. If the KRONOS 200 sat unused long enough, the pack voltage can drop below the BMS protection threshold — typically around 2.5V per cell. At that point, the BMS locks the pack to prevent damage, and the instrument will show no response when you press power. The fix is a slow recovery charge: place the battery on charge and leave it for at least two hours before attempting to power on. Most chargers will detect a trickle-charge condition and begin the recovery cycle automatically if cell voltage is still above 1.5V per cell.

KRONOS 200 display showing inconsistent battery percentage after swapping packs

When a new or fully charged pack is installed, the KRONOS 200's voltage-threshold indicator may show an incorrect or jumping percentage for the first few power cycles. This happens because the instrument's power management firmware is recalibrating its reference points to the new cell's discharge curve. It is not a fault with the battery. Run the instrument through at least one full charge-to-use cycle and complete a calibration cycle via the instrument menu — after that, the percentage readout stabilises to within the expected range.

Frequently Asked Questions

The KRONOS 200 powers on fine but shuts off the moment the probe initialises — is this the battery?

Yes, this is a BMS trip caused by the current spike when the probe module powers up. The original battery's degraded cells can no longer deliver the instantaneous current the instrument demands at sensor initialisation, so the BMS cuts output to protect the cells. A fresh pack with healthy internal resistance handles that spike without tripping. Install the replacement, run the calibration cycle from the instrument menu, then re-test probe initialisation.

Readings are drifting or the logging session resets partway through a long survey — what causes that?

This is a voltage dropout under sustained sensor load, not a probe fault. During extended logging, the combined draw of the sensor array, display, and data recording pulls the pack voltage down in a way that degraded cells cannot maintain steadily — the instrument interprets the sag as a low-power condition and resets the session to protect data integrity. Check the battery terminals for corrosion first, then replace the pack if the cell voltage under load is falling below 6.8V. A new 2200mAh pack maintains a flatter discharge curve across a full logging session.

The KRONOS 200 shuts down during USB data transfer to a PC — why does this happen with a charged battery?

USB data transfer adds a combined draw on top of the instrument's normal operating load — display, processor, and USB controller all run simultaneously. If the pack's cells have degraded even partially, that combined draw pulls terminal voltage below the BMS cutoff threshold faster than either task would alone. The shutdown is the BMS protecting the cells, not a firmware or cable issue. Replace the battery, let it charge fully, then transfer data with the instrument's backlight set to minimum to reduce total draw during the session.
