Motorola two way radio battery advice

How to check two way radio battery ago:
  1. Look for the 3 digit date code on the front of your battery.
  2. The 1st number stands for the year, 2nd and 3rd numbers stand for the week of the year the battery was manufactured.
  3. If the date is more than 1.5 years old, you should replace the battery.
  4. This battery on the left was made during the week of December 17, 2006, or week 51, 2006.

Motorola Two Way Battery Care

  • Charge your new battery overnight before using it. This is referred to as "initializing" and will enable you to obtain maximum battery capacity.New Motorola IMPRES batteries, when inserted into a Motorola IMPRES charger, will indicate a calibration cycle by displaying a steady yellow light on the charge status indicator. Allow this calibration process to complete by not removing the battery from the charger until it's fully charged and displays a steady green light.

    • Nickel Cadmium or Nickel Metal Hydride: Charge 14-16 hours
    • Lithium-ion/Polymer: Charge 1-2 more hours after the charger light turns green.
  • In order to minimize capacity loss and cycle life reduction, new, non-initialized batteries must be stored in well ventilated, cool and dry locations. Batteries stored in these conditions may be stored:If used batteries are to be removed from service for extended periods (greater than 30 days) they should be discharged to about 50% of their capacity. Store in a cool, dry, location.

    • Nickel Cadmium up to 2 years.
    • Nickel Metal Hydrive up to 18 months.
    • Lithium-ion Polymer up to 18 months.
  • Charge a new battery after it is fully discharged (Lithium Ion batteries can be recharged at any time).

  • DO NOT use the battery charger as a radio stand; continuous charging will shorten the battery life.

  • Keep spare batteries for swapping out when your battery needs to be recharged. This is the most cost effective solution for users requiring longer operating time.

  • Batteries that are in storage for more than two months need to be recharged:When ordering new batteries, specify Genuine Motorola brand; they are precisely engineered for use in Motorola two-way radios.

    • Nickel Cadmium or Nickel Metal Hydrive: Charge 14-16 hours
    • Lithium-ion/Polymer: Charge 1-2 more hours after the charger light turns green.
  • When using a Motorola rapid charger, leave the battery in the charger for an additional 1-2 hours after the steady green light appears. Applies to non-IMPRES batteries only.

  • Only charge a battery when it needs it. If it is not fully discharged, do not recharge it.

  • Do not return fully charged non-IMPRES batteries to the charger for an 'extra boost.' This action will significantly reduce cycle life.

  • With proper care, batteries should last about a year and a half..

Battery Analysis

Two-way radio batteries are central to the proper functioning of your radios. Many radio users are unaware that their radio batteries are close to expiring or loosing power. A lifeless battery can cause many radio failures and warning signs are a first clue to a potential problem (see battery care on the advice page). For many operations radios are used on multiple shifts and are not cared for or inspected on a regular basis. Good quality Motorola radios are meant to last even in the most harsh environments, however, your radio is only as good as the battery inside.

Our new FREE Battery Analysis service is designed to get a current reading of your battery status. The new system is called the Battery Optimizing System. This system provides fast, effective and accurate readings of the battery health and can accommodate most any battery.

    Easy to charge

    Posted by Unknown on 2nd Apr 2013

    The pmmn4077 battery is easy to charge. We use the XPR6500 radios and with the charger we use we are able to just keep the battery attached to the radio while charging which is good because we tend to lose our batteries when we separate them from the radio for charging purposes.

    Stays attached to the radio

    Posted by Unknown on 2nd Apr 2013

    I have used a few different types of batteries with my XPR radio, all of which seem to fall of on a constant basis. These batteries stay attached no matter how many times my radio slips out of my hand. They are very durable.

    Sweet Deal

    Posted by Unknown on 2nd Apr 2013

    These batteries are so cheap for Motorola ones. The battery that came with my xpr6500 radio was good but it was hard to keep a battery life all day. We ordered these and they shipped to us within two days. They are great. We got a sweet deal and awesome service.

    Great Battery

    Posted by Unknown on 2nd Apr 2013

    I really like the Lithium Ion batteries. These ones happen to be the best I have used with my xpr radios. My team likes these batteries too because they last almost all day long. Before we were having to take individual breaks to charge up all of the radios. These batteries make our jobs easier.

    WOW. Awesome Battery

    Posted by Unknown on 2nd Apr 2013

    This battery is so great. I had never used impres batteries before and I’ve gotta say I don’t think I will ever go back to regular Motorola batteries. This bettery along with other impres ones really “impress” me.
