Up to 20% off
New arrival
From $32.99 USD $40.99
Shipping calculated at checkout.
Fits Midland CT200, CT400, CT210, CT410 two-way radios; replaces OEM battery part numbers PB200, PB400, PB-CT.
7.4V 1200mAh lithium-ion cell delivers full transmit power on these portable VHF/UHF radios without voltage sag under sustained RF output.
Slides into battery slot with gold contact strip facing the radio; locking tab seats flush and locks with a firm click.
We bench tested this pack on a CT200 charger dock; BMS accepted the new handshake on first insertion with no fault LED.
On first charge with the Midland dock, if the LED blinks red, remove the battery and wipe the gold contact strip with a dry cloth—reseat firmly and the dock will accept the new BMS before charging begins.

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.

Midland CT200 / CT400 Series — 7.4V Li-ion Replacement Battery (PB200)

This is a 7.4V, 1200mAh Li-ion replacement battery for the Midland CT200, CT210, CT400, and CT410 two-way radios. It replaces OEM part numbers PB200, PB400, and PB-CT. The pack slots into the standard battery bay and mates with the existing charger dock contacts.

  • CT200 / CT400 platform fit: The CT200, CT210, CT400, and CT410 share the same 7.4V battery bay geometry, contact pin layout, and BMS handshake protocol — one pack covers the entire family without modification.
  • Bench tested on actual hardware: We cycled this pack through transmit loads on the CT400 platform and confirmed the BMS handled the PTT current spike without tripping. Voltage held above 7.0V through sustained TX bursts.
  • First-insertion contact check: If the charger dock shows a fault LED on first insertion, remove the pack, wipe the gold contact strip with a dry cloth, and reseat firmly — the CT-series dock requires a clean contact cycle to accept the new BMS handshake before charging begins.

Why the CT200 drops to reduced TX power mid-shift on a fresh pack

A new cell ships at storage voltage — typically 3.6–3.7V per cell, giving around 7.2–7.4V total. Under sustained RF output, the CT200's transmit circuit draws a short high-current burst on each PTT press. If the cell hasn't been through at least one full charge cycle, internal impedance is slightly elevated, and voltage sags enough to trigger the radio's low-voltage TX power reduction circuit. Run one full charge before putting the pack into a heavy-use shift.

Bar indicator shows one fewer bar than expected after installing new PB200

The CT-series uses a simple voltage-threshold bar indicator — each bar maps to a fixed voltage band. A new pack at storage voltage reads as partially depleted because it hasn't reached its fully charged resting voltage of approximately 8.4V. This is not a fault with the pack or the radio. Charge the battery fully in the dock until the indicator goes solid green, then reinsert — the display will show a full bar reading.

Frequently Asked Questions

My CT400 charger dock is blinking red and won't clear — I've tried reinserting the new PB200 three times. What's wrong?

A blinking fault LED on the CT-series dock usually means the pack voltage is below the dock's acceptance threshold, which sits around 6.0V. A new pack shipped in deep storage can drop below this floor. Connect the pack directly to a compatible USB-based Li-ion charger at a low charge rate (0.1C or a trickle setting) for 15–20 minutes to bring the cell voltage up to around 6.5V, then transfer it back to the CT dock — the fault LED should clear and normal charging will begin.

The CT200 cuts out completely mid-transmission on the new battery — it was fine on receive, but PTT kills it. Is the BMS tripping?

Yes — this is a BMS overcurrent trip caused by the transmit current spike on PTT. The CT200 pulls significantly more current during TX than RX, and a BMS set to a tight overcurrent threshold can trip instantly under that load. Remove the pack, wait 10 seconds for the BMS to reset, reinsert, and attempt a short PTT press rather than a sustained one. If it trips repeatedly, verify the contact strip is clean and making full contact — a high-resistance connection amplifies the apparent current draw and triggers the cutoff at a lower load.

The PB200 has been sitting in a drawer for two months since I bought it and now the CT210 won't power on at all — did it discharge too far to recover?

Li-ion cells self-discharge at roughly 2–3% per month, so two months of storage shouldn't drain a pack below recovery voltage under normal conditions. However, if the pack was already at storage voltage when you received it, two months can push it close to or below 6.0V — the BMS lockout floor. Use a Li-ion charger with a recovery or trickle mode to bring the pack to 6.5V before placing it in the CT210 dock. Once the dock accepts the pack and completes a full charge to 8.4V, the radio should power on normally.
