Question about Motorola HNN9628A Two-way Radio Battery
When it is cold outside, the batter life can be very short
just dont store the battery in cold and the problem should be gone.
Motorola recommends these temperatures, depending on battery chemistry
NiCd - 30 °C, NiMh - 20 °C, LiIon - 10 °C

First, check the battery and radio terminals. Is everything in place and clean?
There should be 3 terminals on the radio and 6 on the battery. The battery terminals of interest are the bottom 3.
Clean them all with a small flat screwdriver or similar and then give them all a damn good soaking with Brasso or any liquid metal cleaning liquid. wipe off with cotton wool buds or a clean rag.
If the problem persists, its probably the battery itself.
When cold, it affects the internal chemistry of the battery. This can make a poor and tired battery fail early.
Does the same thing happen in the warm?
Get thee to Ebay and purchase a new battery. Its probably not what you wanted to hear, but they really are quite cheap and will last for years if looked after.
P.S. Run the radio until the battery is flat. Do a full charge. And i mean a FULL charge! Then run the radio until flat. Do this 3 or 4 times and the battery might perk up a little!

SOURCE: GP 360 Radio Charger
On a Motorola charger, when the battery is charging the light should be a constant red (or amber depending on the charger). When the charge cycle is complete the light will change to solid green. Sometimes the solid green time is brief, as the battery will begin to lose charge, and the charger will go back into trickle mode and change once again to red (or amber). In most cases, a flashing light indicates a problem, such as a bad or shorted battery, an incorrectly seated battery, dirty battery contacts, or a bad connection with the battery. (Note: Batteries last 18-24 months typically. Check your date code for the age of the battery.)
There were several chargers made for the GP360, including but not limited to a 60-minute charger, a 90-minute charger, a 10-hour trickle charger and a 6-unit gang charger which would be a rapid rate, either 60- or 90- minute. If you would supply your charger's model number we could tell you which one you have.
