Frequently Asked Questions
What is the difference between the PMNN4578 and PMNN4578A?
The PMNN4578A is the newest factory revision of the original PMNN4578 battery. It features the exact same physical dimensions and compatibility but includes slightly upgraded internal cell chemistry for improved reliability.
How long will this 2500mAh battery last on a single charge?
While battery life heavily depends on how often you transmit versus receive, a 2500mAh battery in a digital radio like the DTR700 or TLK100 will typically provide between 14 to 18 hours of continuous operation under a standard duty cycle.
Does this battery require a special charger?
No. The PMNN4578A will charge perfectly in the standard single-unit desktop charger or multi-unit gang charger that originally came with your compatible Motorola radio.
Is this a lithium-ion or nickel-metal hydride battery?
This is a high-capacity Lithium-Ion (Li-Ion) battery. Lithium-ion batteries do not suffer from the memory effect, allowing you to charge them at any depletion level without damaging their overall lifespan.
Will this battery fit my older Motorola DTR550 radio?
No. The PMNN4578A battery is specifically designed for the updated chassis of the DTR600 and DTR700 models, as well as the TLK series. It will not physically fit older generation radios like the DTR550 or DTR410.
Does installing this battery void my radio's warranty?
No. Because the PMNN4578A is a genuine Motorola OEM component, using it will not void the manufacturer's warranty on your radio device.
