IMPORTANT NOTE: Motorola has discontinued the NTN7144 NiCad battery and is offering the WPNN4013 NiMH battery as the replacement battery. Therefore, if you place an order for the NTN7144 battery, then you will receive the WPNN4013 NiMH Motorola Original battery.
NOTE: Battery may not fit in standard carry case.
Fits: HT1000 MT2000 MTS2000 MTX8000 MTX9000 JT1000 MTX838 MTX-LS
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.
