Battery Care and Tips

Portable Battery Care and Tips

Many businesses and organizations rely on two-way radio communications, so battery life is critical for reliable day-to-day operations. The last thing you want is for workers to lose communication when carrying out vital operations. In order to keep communication flowing, it can help to understand battery types, how to charge them, and how to take care of them for the longest life.

Ever wonder if your portable battery is still performing to the capacity it was when it was first purchased?  A Portable battery life is 12-18 months and then it should be replaced for optimal performance. Signs that your battery may not be at the capacity it needs to be is no transmission, not lasting a shift, and not having the distance to talk it use to.  Rassbach Communications can analyze your battery and determine what capacity it is functioning at.  If you have questions regarding your battery care contact us today!

The 5-5-90% cycle

In the radio communications industry, we talk about radios being on a specific cycle. It is called the 5-5-90% cycle time assumption. This means that when you use a radio, 5% of your time is spent transmitting, 5% receiving, and 90% on standby.

OEM rechargeable batteries were designed and precisely manufactured by their engineers to ensure optimum portable radio performance. When staying productive means staying in touch, you need batteries you can depend on day in and day out. You can trust OEM batteries to work better and last longer than ordinary replacement batteries-maximizing productivity and keeping your people in touch.

  • Nickel Cadmium (NiCd)
    Currently the most cost-effective chemistry on the market, Nickel Cadmium batteries give you more watt-hours of operation (per shift) for the least amount of money. These versatile batteries can operate under extreme conditions of cold or heat. NiCd's major drawback is its susceptibility to memory effect and not utilizing its full capacity.

  • Nickel Metal Hydride (NiMH)
    This battery chemistry provides 40-50% longer operation than NiCd. While NiMH batteries are slightly more expensive than NiCd, they are less prone to memory effect and are more environmentally friendly for easier disposal.

  • Lithium Ion (Li-Ion)
    One of the major advantages of Lithium Ion batteries is their power-to-weight ratio, easily exceeding that of NiMH for a lighter, smaller power supply. These high-tech batteries offer a longer operating time and the advantage of not experiencing a memory effect.
  • Lithium Polymer
    Lithium-Ion Polymer batteries are the next generation in battery technology and use a polymer electrolyte instead of a liquid electrolyte. High-conductivity semisolid (gel) polymers form this electrolyte. Lithium-Ion Polymer batteries provide higher specific energy than other lithium battery types and are lighter in weight. Lithium-Ion Polymer batteries can provide up to 24 hours of battery life per charge to a radio using 5-5-90 conditions.

Extending the Life of Your Batteries

There are many ways you can help your batteries last longer:

  • For extending a battery charge during your work shift, only use your radio to communicate when necessary.
  • Keep the dry contacts clean on both the radio and the chargers. This will ensure safe and fast charging. Clean with a cloth or paper towel moistened with rubbing alcohol.
  • Store your batteries in a cool, dry place (at room temperature). Storing a fully charged lithium-ion battery in a hot area is the worst thing you can do to the battery. Do not leave or charge your radio or the battery in your car if it is hot out. Heat is by far the largest factor when it comes to reducing lithium-ion battery life.
  • Overcharging your radio can also reduce battery life. Some manufacturer's chargers automatically go to trickle charge once the charger detects the battery is near the end of the charge to prevent overcharging.

Note: Kirisun batteries have a battery life of 6 months and should be replaced.

Unication Pager Battery Care and Tips

Batteries & Cold Weather

As with any battery-operated device, freezing temperatures of 30 degrees and below may impact the G1's battery life.  The following preventative measures are recommended to maximize battery performance in cold temperatures.

• Ensure that batteries are fully charged prior to any extended exposure to freezing temperatures. Do not leave your G1 in exposed temperatures for long periods of time. It is recommended to keep the pager on you as body warmth helps to protect from cold conditions.

• Replacing your G1 batteries every 6 months is strongly recommended. Replacing your G1 batteries before the start of the cold season will help to maximize battery life. For optimal performance, Unication recommends using at least 1000 mAh NiMH rechargeable batteries.

Replace G1 Batteries Every 6 Months
