When you are constantly in emergency situations, you need to be in constant communication. To ensure that, purchasing Kenwood two way radio batteries is a guarantee that you will have power available to you for your most vital communications equipment. Of the types available there are various features that are important. Chemistries for a Kenwood battery, or any other, include lithium ion, nickel-cadmium, nickel-metal hydride, etc.
The nickel metal batteries provide a very high current output, but they have the problem of "memory," where the battery remembers its maximum charge from previously not being recharged. These batteries can be reconditioned, but at the cost of specialized machinery. Lithium batteries do not have the problem of memory and can last for 10 years on a shelf. The negative is especially important for rescue, lithium batteries cannot be exposed to flame. While none of the battery types should be exposed, lithium Kenwood two way radio batteries cannot. So they are right option for firefighters and rescue who are in fire situations all the time.
ICOM two way radio batteries are designed to suit ICOM two way radios primarily. While you can put an ICOM two way radio battery into another two way radio device, you generally should not do so. The same goes for putting a different brand battery in an ICOM two way radio device. While the battery and two may radio may appear to be interchangeable, this does not mean that they are necessarily compatible with one another. So if you put a Vertex radio battery or a Kenwood battery into your ICOM device, you may run into issues. For this reason, it truly is vital that you pair like with like; using only ICOM two way radio batteries with your ICOM two way radios and other ICOM branded communication devices.
Everything that has already been said about Kenwood battery products and ICOM radio batteries is also true when it comes to Vertex Radio batteries. If you want to get the best possible use out of your Vertex two way radios and Vertex radio batteries, you have to be willing to use the two together exclusively without trying to go the cheaper route with off brand batteries. If you keep your batteries and devices under the same brand, you will certainly get better use and better lifespan out of them.
