Battery Care Tips
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
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 MTP600 / MTP3000 Series — 3.7V Li-ion Replacement Battery
This 3.7V, 2900mAh Li-ion battery replaces the factory pack in Motorola MTP600, MTP3000, MTP3100, and MTP3150 portable radios, along with eight additional MTP-series models. It slots into the same housing footprint and connects to the same battery contacts as the original. Voltage and capacity match OEM spec exactly — 3.7V, 2900mAh (10.73Wh).
- MTP600 and MTP3000 series compatibility: These models share a common battery housing, contact rail, and BMS handshake protocol across the range. The same pack works across all listed variants because Motorola standardised the connector and communication interface on this platform.
- Bench tested on actual hardware: We cycled this pack through transmit loads on MTP3000 hardware. The BMS held stable under PTT-triggered current spikes and resumed normal voltage within expected bounds after each burst.
- 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 MTP platform requires a clean contact cycle before the dock will accept the BMS handshake and begin charging.
Why the MTP600 cuts out mid-transmission on a new battery
A new Li-ion cell ships at storage voltage — typically around 3.6–3.7V — not at full charge. When the radio transmits, the RF amplifier draws a sharp current spike. If the cell hasn't been fully charged first, that spike can pull the pack voltage below the BMS undervoltage threshold, triggering a momentary cutoff. The radio interprets this as a low-battery condition and drops the transmission. Charge the pack to full before putting it into service.
Bar indicator showing one fewer bar than expected on a fresh pack
The MTP series uses a simple voltage-threshold bar display — each bar maps to a voltage band, not a percentage calculated by a chip. A new pack sitting at storage voltage will read one or even two bars low until it's fully charged. This is not a fault with the cell. Fully charge the battery in the dock, then reinsert it into the radio — the indicator will reflect the correct voltage level at 4.1–4.2V.

Frequently Asked Questions
The MTP600 drops to low TX power mid-shift even with a charged battery — what's causing that?
Sustained RF output pulls steady current from the pack, and if cell impedance has climbed — either on an older cycle or from a partial charge — voltage sags under that continuous load. The radio's power control circuit detects the sag and steps down transmit power to protect the link. Check the pack voltage immediately after a low-power event: if it reads below 3.5V under load, the cell is not recovering correctly and the pack needs replacing. A healthy pack under transmit load should hold above 3.6V.
The charger dock fault LED never clears after inserting the new battery — how do I fix it?
The MTP dock checks for a minimum pack voltage before it will accept a charge cycle. If the new pack shipped at a low storage voltage, the dock may read it as a damaged or deeply discharged cell and refuse to initiate charging. Remove the pack, wipe both the battery contact strip and the dock contacts with a dry cloth, and reseat firmly. If the fault LED persists, try a different dock — some older units have a narrower acceptance window and won't recover a pack below approximately 3.2V without a wake-charge cycle.
The MTP3100 radio powers on normally but the battery drains faster than the old pack did after only a few weeks — is that normal?
New Li-ion cells benefit from two or three full charge-discharge cycles before they stabilise at rated capacity. Shallow cycling — frequent top-ups without full discharge — can also cause the voltage-threshold bar indicator to misread remaining charge, making the pack appear to drain faster than it actually is. Run the battery down until the radio signals low battery, then charge fully, and repeat this twice. Capacity should normalise after those conditioning cycles.
