bulging, smoking, flaming batteries

Scary even when it’s not Halloween! This bulging DTR series battery is from a radio that came into Delmmar’s 2-way radio repair center for repair. The customer has chosen to have their DTR650 radio repaired (flat rate $85) and purchase a new battery to replace this bulging one. Bulgy has been disposed of in hazardous waste.

In the news recently there has been a lot of talk about electronics devices catching fire on planes. An educated guess would be the battery in the device was damaged or poor workmanship. It could have been physical or liquid damage, overcharging, poor manufacturing, or the effects of the change in air pressure in the cabin. While we have not heard of any incidents involving 2-way radios (which have restrictions when taken on a plane), users should always use wisdom whether in the air or on the ground.

There are dozens of youtube videos showing these types of batteries in flames once they are abused, overcharged, wet or mistreated.  Short story: If your battery bulges, or shows any sign of puncture/damage DO NOT use it. Motorola has a good explanation concerning the differences between Li-Ion and Li-polymer batteries. You can read it here.

For your two-way radio choose a good name brand battery from a reputable radio dealer. Choose good quality Li-Ion or NiMH batteries instead of Li-Polymer.
