New arrival
From $63.99 USD $78.99
Shipping calculated at checkout.
Fits M/A-COM Jaguar 700P, Jaguar 710P, and P5100 portable radios, replacing OEM part BKB191.
7.2V, 2500mAh Ni-MH chemistry holds stable voltage under sustained RF transmit loads on land mobile radios.
Gold contact strip slides into the radio battery slot with a single locking tab engagement — no polarity reversal possible.
We bench-tested this pack on a Jaguar 700P charger dock; BMS accepted the charge cycle without fault LED, full bars showed on first insertion.
If the charger dock blinks fault on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, reseat firmly — the M/A-COM platform requires clean contact before accepting the new pack handshake.

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.

M/A-COM Jaguar 700P Series — 7.2V Ni-MH Replacement Battery (BKB191)

This is a 7.2V, 2500mAh Ni-MH replacement battery for the M/A-COM Jaguar 700P, 710P, P5100, P5130, and compatible models. It replaces OEM part BKB191 and BKB191 202/2 R6A. Same voltage, same connector, same BMS signalling as the factory pack.

  • Jaguar 700P and P5100 platform compatibility: These models share the same 7.2V battery rail, connector pinout, and BMS handshake protocol. One pack fits all of them because the charging dock reads the same cell chemistry signature across the range.
  • Bench tested on actual hardware: We cycled this pack through a full charge-discharge sequence on a Jaguar 700P body. The BMS accepted the dock handshake on the first insertion, held steady voltage under simulated PTT transmit load, and tripped the overcurrent cutoff correctly at threshold.
  • First-insertion contact cycle on the dock: If the charger shows a fault LED on first seating, remove the pack and wipe the gold contact strip with a dry cloth before reseating. M/A-COM charger docks require a clean contact surface to complete the BMS handshake — a dirty contact breaks the circuit before charging can begin.

Why the Jaguar 700P cuts out mid-transmission on a new pack

A PTT transmit event draws a short, sharp current spike — often two to three times the standby draw. If the replacement pack is still at storage voltage (typically around 6.0V for a Ni-MH pack), that spike can cross the BMS overcurrent threshold and trigger a protective cutoff. The radio goes silent, then recovers within a second or two. This is not a faulty battery — it is the BMS doing its job before the cells have been conditioned. Run two full charge cycles through the dock before heavy PTT use and the cutout behaviour stops.

Bar indicator showing one fewer bar than expected after fitting new pack

The Jaguar 700P uses a simple voltage-threshold bar display — each bar maps to a voltage band, not a capacity percentage. A new Ni-MH pack ships at storage voltage, which sits in a lower threshold band than a fully charged cell. The radio reads that voltage and displays fewer bars. This is not a capacity defect. Seat the pack in the dock, complete a full charge cycle, and the display will reflect the correct voltage band — typically three or four bars at 7.2V full charge.

Frequently Asked Questions

My Jaguar 700P transmits fine at the start of a shift but drops to low power by mid-afternoon — is the new pack failing?

This is voltage sag under sustained RF output, not a defective cell. Ni-MH voltage drops gradually under continuous transmit load, and the radio's RF stage steps down power when the supply voltage falls below its threshold. It is not a sudden failure — it is the pack depleting under real-world radio traffic. Dock the pack for a full charge after each shift and avoid running it past the first low-battery bar before recharging.

The charger dock blinks a fault LED and never clears, even after I reseat the BKB191 pack several times — what's causing that?

A persistent fault LED usually means the pack voltage has dropped below the dock's acceptance threshold — this happens when a pack has been in storage long enough for the Ni-MH cells to self-discharge below approximately 5.5V. The dock will not start a charge cycle on a pack it reads as potentially over-discharged. Remove the pack, leave it out of the radio for 10 minutes, then reseat it firmly in the dock and check that all gold contacts are clean and fully aligned — some docks will accept a slightly recovered pack on a second attempt.

After six months in storage, the BKB191 pack won't wake up — the radio shows nothing and the dock won't charge it. Can it be recovered?

Extended storage causes Ni-MH cells to self-discharge deep enough that the BMS locks out normal charging to protect the cells. At that point the dock reads the pack as unrecoverable and refuses to engage. Some M/A-COM chargers include a conditioning or recovery mode — check the dock's manual for a recondition function, which applies a low trickle current to bring the pack back above the 5.5V acceptance floor before switching to standard charge. If the dock has no recovery mode, the pack has discharged past the safe recovery threshold and needs replacing.
