There are a few Motorola CP200 batteries available:
Motorola NNTN4497 – This is the most popular model of battery for the Motorola CP200 radios. This Li-ion battery has over 2200 mAh of capacity and will last over 12 hours in regular radio operation. This is the standard battery that is supplied with the Motorola CP200 and Motorola CP200d series of radios.
Motorola NNTN4851 – The NNTN4851 is a NiMH battery that is good for use in extreme temperature environments. With less capacity than other CP200 batteries we only recommend this for users that will be using the radios in extreme cold or warm locations.
Motorola NNTN4970 – The Motorola NNTN4970 is a slim line Li-ion battery for use with Motorola CP200 series of radios. Although it is lower in capacity, it is also lighter weight and easier to carry for daily use. With six to eight hours of talk time, the NNTN4970 battery works well for some customers.
We also wanted to make you aware of two other budget-priced batteries that are available for the CP200 radios. These batteries are not of the same quality and life of the authorized Motorola Batteries, but may work well for customers on a budget. The MagOne by Motorola PMNN4458 &PMNN4072 batteries are available for customers working on a tight budget and not using the radios for safety.
If it was my money, we would recommend purchasing the NNTN4497 battery. It has excellent life at 10-12 hours and has an excellent form factor for easy to carry around on your belt. We see almost none of the batteries come back for warranty – they work perfectly. We think the little extra you’ll spend will be made up in the convenience of long battery life, no warranty hassles and works well in all environments.
