Different strokes for different folks, right? That holds true in the case of two way radio batteries, as there is more than one type. As a result, understanding which ones will work best for your application—and how to take care of them—is the secret to making your batteries last.
Bearing this in mind, there are several things you should know about the different chemistries of two way radio batteries.
Nickel Cadmium (NiCd) two way radio batteries are a very cost-effective option for many applications, particularly since they provide longer cycle life than other types of batteries. NiCD is ideal for users who need high-performance batteries and who communicate under extreme conditions of cold and heat (-20 to 120 degrees Fahrenheit). However, NiCd two way radio batteries can experience what’s commonly known as “memory effect” and not return to full capacity if they are recharged too soon.
Nickel Metal Hydride (NiMH) two way radio batteries can work 40-50% longer between charges than NiCd batteries of similar size, but they do not operate as efficiently in extreme temperatures. However, NiMH two way radio batteries have the advantage of containing fewer toxic chemicals, so disposal is more environmentally friendly.
Lithium Ion (Li-Ion) two way radio batteries have a higher energy-to-weight ratio than NiMH batteries, offering a lighter, smaller power supply for more compact devices. Unlike NiCd two way radio batteries, these batteries do not experience “memory effect.”
Using the right two way radio batteries is half of the equation. The other half, and equally as important, is recharging and maintenance. Before you use your two way radio batteries for the first time, charge them overnight. This is know as “initializing” and allows for maximum battery capacity. For example, in the case of Motorola Impres batteries, the calibration process is complete when the initial yellow indicator light turns to steady green.
Battery storage is important as well. Keep non-initialized two way radio batteries in a well-ventilated, cool, and dry area. If you have batteries that are removed from service, they need to be discharged to about 50% of their capacity before you place them in storage. Another point to remember is not to leave your radios or fully charged two way radio batteries in the charger when not charging, as doing so will shorten battery life.
Finally, charge your two way radio batteries only when they need it. Don’t recharge a battery that’s not fully discharged. And always carry a spare with you if you anticipate a long operating time.
