Handheld walkie-talkies are widely used in petrochemical, hotel, restaurant, and school settings. They are powered by a built-in rechargeable battery. However, in cold areas, conventional batteries cannot supply power normally, necessitating low-temperature batteries. Consequently, low-temperature walkie-talkies become an important selection factor for consumers.
A walkie-talkie (two-way radio) is a portable device that sends and receives electromagnetic waves for communication over certain distances. Easy to operate and low-cost, they are widely used in public safety, production, engineering, and hospitality. Powered by rechargeable batteries, low-temperature walkie-talkies are essential in cold areas where conventional batteries fail. So having high-quality batteries for use in low-temperature scenarios is crucial to ensure proper functionality.

Walkie-talkie batteries on the market can be divided into lithium batteries
(Li-ion), nickel-metal hydride batteries (Ni-MH) and nickel-cadmium batteries
(Ni-Cd). In the voltage and discharge performance, nickel-metal hydride and
nickel cadmium batteries are similar, but nickel-metal hydride batteries have a
higher energy density. The capacity of one No.5 NiMH battery ranges from 600mAh
to 1800mAh, there is no "memory effect", safe and reliable, with MA
explosion-proof certification, and no pollution to the environment.Grepow, as a
source manufacturer of NiMH batteries, with 25 years of experience in
manufacturing, independent research centers and a number of customer cases, to
form a low-temperature walkie-talkie suitable for diversified solutions, such as 3S1P (3.6V) and
4S1P (4.8V), etc., commonly used capacity 1300mAh and 1800mAh.
