TS-50 Lithium memory battery replacement 13 August 2022
Channel and frequency memory loss when disconnected and reconnected
with 12VDC supply.
When the radio is reconnected to the 12VDC supply, it resets to 14.0MHz, indicating that the memory battery has died.
Replacing the radio's lithium memory battery with the original type is difficult to source and expensive. Therefore, a less expensive and more readily available CR2430 lithium battery was chosen. The CR2430 battery required some modification to the tag, and a short copper wire was soldered to the negative side as there was no suitable tag on this side. Please refer to the photo below.
The Velcro attachment tab was recovered from the original battery and used on the new battery to prevent movement.
the battery is connected the radio must be powered off then on to
ensure the life of the battery per Kenwood Service Bulletin ASM-1015
was powered up and worked perfectly.
