The PTM-6305 is a premium aftermarket energy solution designed to replace the OEM Motorola PLN6305 and RLN6351 battery packs. Built to power the Motorola RDX Series, including the popular CP110, RDU2020, and RDU4100, this battery operates at a stable 7.4V. It utilizes advanced Lithium-Ion chemistry, which offers a superior power-to-weight ratio compared to older Ni-MH options, ensuring the radio remains lightweight on the user's belt while delivering consistent voltage throughout the discharge cycle.
Constructed for durability, the cells are housed in a rugged polycarbonate casing that is ultrasonically welded to prevent splitting during drops or impact. The external contacts are gold-plated to ensure corrosion resistance and maximum electrical conductivity with the radio chassis. With a capacity rating of 2200mAh (typical for high-capacity versions), this two-way radio battery provides extended operational time, making it the ideal choice for businesses looking to refresh their aging communication fleets without the high cost of OEM replacements.
Key Advantages
High-Density 2200mAh Capacity
Standard batteries often degrade after a year of daily use, leading to radios dying mid-shift. This unit features high-quality Li-Ion cells with a capacity of 2200mAh, offering significantly more runtime than standard 1100mAh packs. For high-traffic users, this means the Motorola CP110 will remain operational for 12+ hours on a single charge. This extended endurance eliminates the need for staff to swap batteries during lunch breaks or carry spares, streamlining workflow and ensuring that communication lines remain open from store opening to closing.
Intelligent Safety Circuitry (PCM)
Safety is paramount when deploying lithium batteries in a commercial environment. The PTM-6305 integrates a Protection Circuit Module (PCM) that actively monitors internal voltage and temperature. This smart chip prevents common failure modes such as overcharging, over-discharging, and short circuits. It ensures the battery can be safely left in a desktop charger overnight without risk of thermal runaway or cell swelling. This built-in protection not only safeguards the user but also prolongs the overall lifecycle of the battery by maintaining cells within their optimal voltage range.
Zero Memory Effect Technology
Unlike older Nickel-Cadmium (Ni-Cd) batteries that required a full discharge before recharging to preserve capacity, this Li-Ion battery suffers from zero memory effect. Users can top up their radios at any time—whether during a break or shift change—without degrading the battery's long-term ability to hold a charge. This flexibility is crucial for fast-paced retail and event environments where radios are constantly docked and undocked, ensuring maximum ROI on your equipment investment.
Use Scenarios
Retail Store Management
Large-box retailers and grocery chains rely heavily on the CP110 and RDX series for floor coordination. A manager equipped with this high-capacity battery can coordinate inventory checks, cash register overrides, and customer service calls for a full 10-hour shift without the radio beeping "low battery." The lightweight Li-Ion design reduces fatigue for staff wearing the radio on a belt clip all day.
School Campus Administration
Custodians and administrators use RDU radios to manage maintenance and student safety. The rugged housing of the PTM-6305 withstands the inevitable knocks and drops that occur in a busy school environment. The reliable connection ensures that in the event of a lockdown drill or emergency, the power source will not fail, providing peace of mind for campus security teams.
Light Industrial Warehousing
In small to mid-sized warehouses, the CP110 is a workhorse. Forklift drivers and pickers need a battery that resists vibration and dust. The tight mechanical tolerances of this replacement pack ensure it locks securely into the radio, preventing power interruptions when the user jumps off a forklift or navigates narrow aisles. The extended runtime handles the high transmit duty cycle often found in logistics operations.
FAQ
Is this battery compatible with the Motorola RDU4100?
Yes, the PLN6305/RLN6351 form factor is the standard battery for the entire Motorola RDX series, including the CP110, RDU2020, RDU2080d, RDU4100, and RDV2020.
Does the battery come with a belt clip?
Yes, this battery model is typically designed with the track to accept the standard spring-action belt clip, and one is usually included in the box (please confirm specific SKU contents).
Will this charge in my original Motorola charging tray?
Absolutely. The external contacts and physical shape are engineered to fit perfectly into the standard RLN6304 or equivalent Motorola drop-in chargers.
How many charge cycles can I expect?
Under normal usage conditions, a high-quality Li-Ion battery like this will deliver approximately 300-500 full charge/discharge cycles before capacity drops below 80%.
Is this a high-capacity version?
Yes, at 2200mAh, this is considered the high-capacity Ultra High Capacity (UHC) version, offering nearly double the runtime of the standard slim 1100mAh battery.
