Hytera HP600 Replacement Battery BL2002 7.4V 2000mAh

Up to 20% off
New arrival
From $64.99 USD $80.99
Shipping calculated at checkout.
Fits Hytera HP600, HP680, HP605, and HP685 portables; replaces OEM part numbers BL2002 and BP2002.
7.4V 2000mAh lithium-ion cell delivers sustained RF output across shift-length operations without voltage sag.
Slide connector seats flush into the radio battery slot with a single locking tab on the left edge.
We bench-tested this pack on an HP680 charger dock; BMS accepted the handshake on first insertion without fault codes.
If the charger dock shows a fault LED after inserting this cell, remove the battery and wipe the gold contact strip with a dry cloth before reinserting — the Hytera platform requires a clean contact cycle to accept the new BMS handshake.

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

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.

Hytera HP600 / HP680 Series — 7.4V Li-ion Replacement Battery (BL2002)

This 7.4V 2000mAh Li-ion battery replaces the Hytera BL2002 / BP2002 pack in the HP600, HP605, HP680, and HP685 portable digital radios. These radios run on a single lithium-ion cell stack with a BMS that handles both charge control and transmit-load protection. Capacity is sourced from the product specification — 2000mAh / 14.8Wh.

  • HP600 / HP680 platform fit: The HP600 and HP680 share the same battery bay geometry, contact pinout, and BMS handshake protocol. A single pack covers both chassis lines because Hytera kept the power rail and connector spec identical across this generation.
  • Bench tested on actual hardware: We cycled this pack through charge and discharge on the HP680 platform. The BMS accepted the dock handshake within the first insertion, held voltage above the low-battery threshold under simulated PTT load, and tripped the overcurrent protection correctly at the expected current ceiling.
  • First-insertion contact check: If the charger dock shows a fault LED on first seating, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly. The HP600 dock requires a clean contact cycle to complete the BMS handshake before charging begins.

Why the HP600 cuts out mid-transmission on a freshly inserted battery

New lithium-ion cells ship at storage voltage — typically around 3.6–3.7V per cell, not full charge. When the HP600 keys up for a transmit burst, the current draw spikes sharply. If the cell is at storage voltage, the BMS can read that spike as an undervoltage event and momentarily cut the output. The radio drops out, then recovers within a second or two. This is not a fault — charge the pack fully before first field use and the behaviour stops.

Bar indicator showing one fewer bar than expected after a full charge

The HP600 series uses voltage-threshold bar indicators, not a fuel gauge chip. Each bar step corresponds to a voltage band the radio reads from the pack terminals. A new cell that has only partially settled after its first charge cycle may rest at a voltage that sits just below the top threshold, dropping the display one bar short. Run a full charge, let the pack rest off the dock for ten minutes, then reinsert — resting voltage should settle above 8.3V and the display will show the correct level.

Frequently Asked Questions

The HP600 dock LED keeps blinking red and never switches to charge — pack is seated correctly

A blinking fault LED on the HP600 dock usually means the pack voltage has dropped below the dock's acceptance threshold, which is roughly 6.0V for a 7.4V Li-ion pack. The dock's charge circuit won't initiate below that floor as a safety measure. Remove the pack, wipe the gold contact strip clean, reseat firmly, and hold it in place for five seconds — a dirty or loose contact can mimic a low-voltage fault. If the LED still blinks, check the resting pack voltage with a multimeter across the contacts; anything above 6.0V should trigger normal charging.

Radio drops to noticeably weaker TX output after the first few hours of a shift — battery bar still shows charged

This is voltage sag under sustained RF load, not a capacity issue. As the cell depletes toward the mid-charge range, internal impedance rises and the voltage dips further under the sustained current draw of transmit. The HP600 interprets that dip as a signal to reduce TX power to protect the circuit, even when the bar indicator still reads mid-level. It is normal behaviour — carry a second charged pack for shifts longer than a standard duty cycle, or reduce the frequency of long PTT holds to extend usable transmit capacity.

Pack was stored unused for several months and the HP680 dock won't recognise it at all

Extended storage below approximately 5.5V can push the cell into a state where the BMS locks out to prevent charging a critically depleted pack. The dock won't initiate a charge cycle because the pack is below its recovery floor. Some HP680 docks have a recovery or conditioning mode — check the dock's indicator sequence for a slow single-blink pattern, which signals recovery mode is active. If your dock doesn't support recovery charging, measure the pack voltage; anything below 5.5V across the terminals means the BMS lockout is permanent and the pack needs replacement.
