Tip for cleaning Dirty Battery Charger Connections
Dirty battery charger connections can prevent the Walkie Talkie battery from charging. This article provides a secret industry tip for cleaning charger connections.
A customer in the Northern City of Hull, in the UK was having problems with his six-way multi charger.
The issue was not a fault with the charger, but due to the contacts that form the charger connections.
The problems was both on the battery and the charger battery contacts, which had becoming dirty.

Over time the copper contacts on both the battery and the charger, which need to be clean, become dirty.
This is particularly an issue in harsh industrial environments, and can be a cause of the radio charger appearing to have a fault, when the radio is placed into it to charge.
A tip is to regularly clean both the copper contacts at the base of the rechargeable battery (on the back of the radio), and also lightly clean the spring contacts on the charger.
Ensure that the charger is switched off and disconnected from the mains power supply.
Then using a soft pencil eraser (rubber), gently rub the copper contacts to clean them.
This will help make electrical contact between the charger and the radio battery.
Why have the connections become dirty?
Air contaminants such as industrial dust, or corrosive atmospheres such as the marine industry, cause a build up of dirt or corrosion on the electrical contacts.
Preventative Maintenance of battery Connections
To prevent the inconvenience of your radios suffering this charging fault, regular cleaning and inspection of the battery and charger contacts is advised by Yesway.
For light manufacturing environments, once a month will normally be sufficient.
For heavy industrial and marine offshore environments, a weekly check and a quick clean is advised.
Regular cleaning will help ensure staff safety, by having radio equipment that is properly charged, and ready for potential emergency situations.
