IP54 Weather Resistance
Rated IP54 — protected against dust ingress and water splashing from any direction. Suitable for outdoor use, construction sites, warehouses, and any environment where radios are exposed to the elements.

Frequently Asked Questions
Is this compatible with the Motorola CP100D?
Yes. The PMNN4476 is a genuine Motorola OEM battery fully compatible with the CP100D series two-way radio, as well as the CP185 and the other CP and P series models listed above. It is a direct drop-in replacement for the original battery with no modifications required.
What is the difference between PMNN4476 and PMNN4476A?
These are the same battery. Motorola adds a suffix letter (such as "A") to denote production version revisions. The specifications, compatibility, and performance are identical. Motorola's own guidance is to ignore the suffix letter for ordering purposes — you will receive the current production version available at the time of your order.
Does this replace the PMNN4081 battery?
Yes. The PMNN4476 is the direct replacement for the older PMNN4081 and PMNN4081BR batteries. It is a drop-in fit for all radios that previously used the PMNN4081, with the same form factor and connector. The PMNN4476 also offers improved lithium-ion chemistry over the older NiMH PMNN4081 — providing better capacity, no memory effect, and a lighter pack.
Which charger do I need for this battery?
The PMNN4476 is compatible with Motorola single-unit chargers and multi-unit gang chargers designed for CP and P series radios, including the PMPN4174 single-unit charger and WPLN4114 multi-unit charger. It is also compatible with Motorola IMPRES intelligent chargers for automatic battery conditioning and capacity reporting. Contact ITFactory.ca for compatible charger recommendations for your specific radio model.
Why buy a genuine Motorola battery instead of a third-party replacement?
Genuine Motorola batteries are engineered and tested specifically for the radio models they are designed for — ensuring correct voltage regulation, proper fit, and full compatibility with Motorola IMPRES chargers and battery management systems. Third-party batteries may offer lower upfront cost but can deliver inconsistent capacity, shorter cycle life, and in some cases may void the radio's warranty or damage the charging system. For fleet operations where radio reliability is critical, genuine OEM batteries are the reliable choice.
