Up to 19% off
New arrival
From $42.99 USD $52.99
Shipping calculated at checkout.
Fits Motorola CP110, EP150, A10, A12 and replaces PMNN6035, RLN6351A, 6080384X65 battery packs.
Delivers 7.5V at 2200mAh capacity for extended transmission cycles on compact portables.
Gold contacts mate flush with radio connector slot; locking tab seats firm without forcing.
We bench-tested this cell on a CP110 radio through full discharge cycles; BMS accepted charge handshake without fault codes.
If the charger dock shows a fault LED on first insertion, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly — the Motorola platform requires a clean contact cycle to accept the new BMS 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.

Motorola CP110 / EP150 / A10 / A12 — 7.5V Li-ion Replacement Battery (PMNN6035)

This 7.5V 2200mAh Li-ion battery replaces OEM part PMNN6035 and fits the Motorola CP110, EP150, A10, and A12 portable two-way radios. It slots into the same battery bay as the original pack and uses the same connector pinout and BMS handshake protocol. Capacity is drawn from product data: 2200mAh / 16.5Wh.

  • CP110 / EP150 / A10 / A12 platform fit: These models share the same 7.5V battery bay, connector footprint, and BMS communication line. One pack covers the full set — no adapter or wiring change needed.
  • Bench tested on actual hardware: We ran this pack through transmit-cycle loads on CP110 hardware. The BMS handled PTT current spikes without tripping, and the charger dock accepted the pack after a clean contact seating on first insertion.
  • Contact strip seating on first insertion: If the charger dock shows a fault LED after fitting this pack, remove the battery, wipe the gold contact strip with a dry cloth, and reseat firmly. The CP110 charger requires a clean contact cycle to complete the BMS handshake before it will begin charging.

Why the CP110 drops to reduced TX power mid-shift on a new battery

New Li-ion cells ship at storage voltage — typically around 3.7V per cell — not at a full charge. Under sustained RF output, the radio's power amplifier draws peak current that the storage-voltage cell can't sustain without voltage sag. The radio interprets that sag as a low-battery condition and steps down transmit power automatically. A full charge cycle before the first shift eliminates the sag and restores full RF output.

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

The CP110 reads pack voltage against fixed threshold levels to display its bar indicator — it has no fuel-gauge chip, only voltage checkpoints. A new pack at storage voltage sits below the top threshold, so the radio shows one or two bars even though the cell is not depleted. Charge the pack fully in the OEM or compatible dock until the charge LED goes solid green. After a complete charge, open-circuit voltage should read 8.3–8.4V and the radio will display a full bar indicator.

Frequently Asked Questions

My CP110 cuts out completely when I press PTT — the radio goes dead for a second then comes back. Is this the battery?

This is a BMS overcurrent trip caused by the transmit current spike when PTT is pressed. If the pack is at storage voltage rather than fully charged, the cell can't handle the instantaneous draw and the BMS cuts power momentarily. Fully charge the battery first — if the cutout still happens on a charged pack, wipe the gold contact strip and reseat the battery to ensure the BMS is communicating cleanly with the radio. A healthy charged pack should hold steady through repeated PTT cycles without dropping out.

The charger dock is blinking a fault LED and won't accept the new pack — I've tried reinserting it several times.

A fault LED on first insertion usually means the dock can't read the BMS because the gold contacts aren't making clean electrical contact. Remove the pack, wipe the contact strip with a dry lint-free cloth, and reseat it with firm, even pressure until you feel it click into the bay. If the fault LED persists after a clean reseat, check that the cell voltage hasn't dropped below the dock's acceptance threshold — a pack that has been stored for a long time may read below 6V and some chargers won't begin a charge cycle below that floor. In that case, use a Li-ion recovery charger set to 7.5V to bring the pack up to acceptance voltage before returning it to the dock.

The radio works fine on transmit but the battery drains much faster than the original after a few weeks of use — what's causing that?

Shallow cycling is the most common cause — if the CP110 is topped up after short shifts without ever running the pack down, the usable voltage window narrows over time and capacity fade sets in early. This affects any Li-ion cell, not just replacement packs. Allow the battery to discharge to the point where the radio shows one bar before recharging, and complete the full charge cycle each time. Running two or three full discharge-recharge cycles resets the effective voltage range the BMS works within and restores the capacity you expect.
