Battery will charge if off of radio will not charge if attached to radio

I have a Motorola HT750 2way radio used for the fire department.
If you take the battery off of the radio unit and place it in the charger it will charge however, if you put the battery on the unit and place the whole radio in charger I get a red flashing light indicating that it is unchargeable.

Why is this??

Thanks Joey in Centre Alabama

Look on the battery , you sould see a 3 digit code. EG if you see a code like 458 . this means week 45 ,2008 or if it is 123. this means week 12 at 2003. The motorola batteries last up to 2 yrs. if it older than 2 years old , replaced the battery

Motorola FIRE XT Tips for extending battery life
Back to Previous Page

Are there any tips on how to extend the battery life?
Things you should know about charging your battery.

New batteries are not fully charged. Plug the battery charger into your phone and an electrical outlet. Your phone might take several seconds to start charging the battery.
Tips:
  • It may take several charging cycles for your battery to reach optimum performance.
  • The battery charger shipped with this device is designed specifically for Motorola mobile phones. Other chargers might take longer to charge your battery, or cause your calls to fail during charging.
  • You can charge your phone via USB cable but this charging time will vary based on computer specifications.
Tips to extend battery life:
  • Select a shorter backlight duration
  • Lower the display brightness
  • Use the AC adapter to charge your phone whenever possible
  • Turn Bluetooth off when not in use
  • Turn Wi-Fi off when not in use
  • Close any third party applications running in the background
  • Playing music, videos and viewing images in your phone will affect your battery life
General Battery use & safety
  • Motorola recommends you always use Motorola-branded batteries and chargers. The warranty does not cover damage caused by non-Motorola batteries and/or chargers.

    Caution: Use of an unqualified battery or charger may present a risk of fire, explosion, leakage, or other hazard. Improper battery use, or use of a damaged battery, may result in a fire, explosion, or other hazard.
  • Your battery can be charged without it being fully depleted, and can be charged every day if desired.
  • Battery usage by children should be supervised.
  • Important: Motorola mobile devices are designed to work best with qualified batteries. If you see a message on your display such as Invalid Battery, Invalid Charger or Unable to Charge, take the following steps:
    • Remove the battery and inspect it to confirm that it bears a Motorola "Original Equipment" hologram;
    • If there is no hologram, the battery is not a qualified battery
    • If there is a hologram, replace the battery and retry charging it
    • If the message remains, contact a Motorola Authorized Service Center
  • New batteries or batteries stored for a long time may take more time to charge.
  • Charging precautions: When charging your battery, keep it near room temperature. Never expose batteries to temperatures below 0°C (32°F) or above 45°C (113°F) when charging. Always take your mobile device with you when you leave your vehicle
  • When storing your battery, keep it in a cool, dry place.
  • It is normal over time for battery life to decrease, and for the battery to exhibit shorter runtime between charges or require more frequent or longer charging times. Motorola batteries are designed to last between 350-700 charge/discharge cycles at room temperature. This amounts to approximately a year to a year and a half of battery use for most people.
  • Avoid damage to battery and mobile device. Do not disassemble, open, crush, bend, deform, puncture, shred, or submerge the battery or mobile device. Avoid dropping the battery or mobile device, especially on a hard surface. If your battery or mobile device has been subjected to such damage, take it to a local service center before using. Do not attempt to dry it with an appliance or heat source, such as a hair dryer or microwave oven.
  • Use care when handling a charged battery-particularly when placing it inside a pocket, purse, or other container with metal objects. Contact with metal objects (such as jewelry, keys, beaded chains) could complete an electrical circuit (short circuit), causing the battery to become very hot, which could cause damage or injury.

Motorola HTN9014c


Here are a few thoughts concerning charging a HNN9018 or HNN9044 battery in a SP50 radio:

1) Check the date code on your battery. Rechargeable batteries have a life expectancy of 2-3 years. Motorola brand batteries have a 3-digit number date code. The first number is the year of manufacture, and the next two numbers are the week of the year. Example: 352 would be 2013 (or 2003) the 52nd week.

2) Try another radio/battery in the charger and see if you have the same results.

3) Try charging the battery outside the radio. It will set front to back in the charger. The battery has an arrow on the bottom of it showing you which way to put it in the charger. If the battery charges in the charger without being in the radio, then your radio has a problem with the charging circuitry.

4) Clean your battery contacts with a pencil eraser, both inside the radio and outside, as well as on the battery itself. This radio's outside contacts are easily covered by film from hand oil and it will prevent the battery from getting a good charge.

5) Test your radio with another known good battery. If your radio is not working with the original battery and it appears to have not charged, it could be a radio problem, not a battery problem.

6) Try your radio in a different charger and see if you get the same result.

By this point in troubleshooting you should be able to determine if it is the battery, radio or charger.

Best regards.

I have a motorola AXU4100 radio. Every time I use it to talk it shuts off.


It is likely your battery pack is not fully charged or it is in need of a new battery. It takes more energy to transmit than to receive. Pressing the PTT uses quite a bit of power and will easily shut down a radio needing a battery (or charge). If you feel you battery is still good (less than 2 years old), you might check your charger to see if it is functioning correctly.

Best regards.

Wondering about a charger


The "alkaline" version of your radio uses thee "AA" batteries and is not equipped for using a charger. Don't panic though, just visit any store with an electronics department. You can pick up NiMH rechargeable batteries and a generic charger. You have to remove the batteries from the radio to charge them, but you can always keep an extra set of batteries charged and ready for use.

Motorola FV200R Talkabout dosent turn on


Yes, it is likely you need new battery packs. The Li-Ion batteries have a 12-18 month life expectancy. They will sometimes go longer if the radios are charged and depleted at least once a month. This style battery should be available from your local Motorola dealer on online at Motorola. http://www.store.motorola.com/mot/en/US/adirect/motorola?cmd=catDisplayStyle&catKey=601560

Motorola CP040 charging time


The rapid rate charger WPLN41__ will typically charge a battery in 90-120 minutes. Your battery should be depleted or nearly depleted when you place it in the charging stand. Be certain your radio is always turned off, when charging an attached battery. The NiMH battery will generally go 12-16 hours on a charge when new. If you work an eight hour shift, you might see if the radio will go 2 days on a charge. Later as the battery ages, you will need to charge it nightly. (Think of putting it in the charger as putting it to bed at night.)

Rapid charging is necessary on NiMH and Li-Ion batteries. They require a "hotter" charger, a fast rate, to completely charge the battery. It will not harm this chemistry of battery. It is safe to leave the battery on the charger overnight, or for a weekend. We would not recommend leaving the battery on the charger longer periods of time, as that will age the battery and reduce its life.

(Sidenote: Frequent rapid charging will however reduce the life of a NiCD battery.)

I have a motorolla jt100 with no sound


Since you are receiving the weather (Wx) channel, the radio appears to be receiving fine. It might be that your fire frequencies are not programmed into the radio. Check your programming, as well as checking your scan list. The Wx channel should not be included in the scan list, as there is constant radio traffic on this frequency, and your radio would get stuck there during the scan process.

MOTOROLA T5522 BATERIES


Hello mironas3,

A general rule of thumb when dealing with rechargeable battery packs is to take the capacity of the battery divided by the charge rating of the charger and then add an additional 10%.

Offhand I am not sure what the voltage / capacity or voltage / charge rating of the battery and charger are but you can determine that by examine the labels on both items. Let’s say (for example) that your battery is listed as 7.2 volts and 1,000 mAH and your charger is rated as 9 volts and 100 mA. (These are just theoretical examples. Substitute the numbers from your own items.) You would divide 1,000 mAH by 100 mA to equal 10 hours. Then add 10%. So you expect a full charge to take around 11 hours time.

Of course, actual charge time will vary depending on how discharged the batteries are when you start charging them. Since the charger that Motorola provided doesn't have a charge indicator determining when the batteries are done charging is a matter of making an educated guess. If you touch the batteries while they are charging and they feel warm to the touch, that's a pretty good indication that they are done or nearly done charging as once the batteries are topped off excess power will turn into heat. (Note that batteries in a charger should never be HOT. If they are ever more then just slightly warm, something is wrong with the battery or the charger or both.)

Also, just a word of warning here: remember to always use the correct manufacturer recommended charger. Substituting a charger with twice the charge rate to charge the batteries in half the time is not a good idea. Rechargeable batteries are meant to be charged slowly. Fast chargers exist but they typically have built-in circuitry that pulses the charge rate to prevent the batteries from overheating. Using the wrong charger can result in damage to your battery or radio or worse could possibly even lead to a fire.

Best Regards,
Ken
