Kaito BT500 Replacement Rechargeable Battery Pack for KA500, KA550, KA600 Voyager Radios

The old battery finally died after years of faithful duty. I use the rechargeable battery as my main power source and use the alkaline as a backup. At the end, the battery would keep the radio going for 20 minutes or so and I knew it was time to replace it. I expect this one to last another 6 or 7 years.

Good item /fast shipping buy with confidence/ AAA+++

Direct fit for my device

Put this battery pack in my Kaito ka500 and it showed a full charge. Happy to have a spare, just in case.

I bought the radio used and I'm glad I bought a new battery it has extended life over the other battery the cool feature about that the old battery can be used for backupsIf you have an emergency radio I highly recommend you have emergency backup power

Good so far. holds a charge

So far so good. I have not had it but a week in my old Eton, which I was ready to “deep six” for not being able to hold a charge overnight. My normal routine would be to fully changes this from an adapter, but I just replaced the battery (simple plug/play) stuck it on a window sill that gets full sun for at least 3 hrs a day, and wham... the clock is keeping time again and the radio plays. It worked. The old battery was no less than 8 years old, so I wasn’t expecting much. Will update after our first power failure.

For my application anyway. It was also keyed differently so I shaved the plastic off and got it to fit but still not working. Then I noticed the black and red wires were opposite of what my old battery was. Flipped the connection over (which wasn’t easy due to spacing) and it powered on my device. So, fyi and all…
