Motorola NTN7144 Two Way Radio Battery Tips
What's the best battery for two-way radios?Most two-way radios use nickel-cadmium. These batteries are durable and forgiving if abuse. The recommended alternative is nickel-metal-hydride, a
Motorola NTN7144 Two Way Radio battery that has higher energy density and contains no toxic metals.
Comparing the two, nickel-cadmium
Motorola NTN7144 Two Way Radio batteries have the advantage of maintaining steady high capacity and low internal resistance through most of their service life. A nickel-metal-hydride
Motorola NTN7144 Two Way Radio battery, on the other hand, starts with good capacity and low internal resistance but the resistance increases after a few hundred cycles.
Nickel-based two-way radio batteries are high in maintenance. Periodic discharge cycles are needed to prevent crystalline formation on the cell plates, also known as memory. Nickel-cadmium is more receptive to memory than nickel-metal-hydride because both nickel and cadmium plates are affected by memory.
What are the charging cycles of Nickel-cadmium and Nickel-metal-hydride
Motorola NTN7144 Two Way Radio Batteries?Nickel-cadmium
Motorola NTN7144 Two Way Radio batteries should be exercised once ever 1 to 2 months, whereas nickel-metal-hydride
Motorola NTN7144 Two Way Radio batteries can get by with a deliberate full discharge once every 3 months. Without proper maintenance, the advantage of nickel-cadmium over nickel-metal-hydride in terms of cycle life cannot be realized.
Can I use a Lithium Ion
Motorola NTN7144 Two Way Radio Battery?Lithium-ion has been tested for two-way radio batteries and the results are positive. Substituting lithium-ion with nickel-based will require chargers specifically suited for this chemistry. Nickel-cadmium and nickel-metal-hydride can often share the same charger.
