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.

I ordered this to replace the original solar-charged and hand-crank-generator-charged battery in an "eton" FRX3 emergency radio/light. I mistakenly plugged in the battery wire plug backwards (because it fit OK) and the radio would not operate. I reversed the plug and it seems to charge and work good.
