One walkie talkies volume is very low

I believe for the FR60 walkie-talkies, if they are not sending or receiving, the issue could be related to the antenna, battery, or internal components. You can try replacing the batteries and/or antennas to see if that resolves the issue.

As for the T5820 walkie-talkie, if the rubber on the antenna is broken, it's likely that the antenna itself is also damaged. In this case, you can try replacing the antenna with a new one. Antennas are typically available for purchase online or at electronics stores.
In terms of cost, repairing older walkie-talkies like these may not always be cost-effective. If the repairs are extensive or require replacement of major components, it may be more practical to purchase new walkie-talkies instead.
Below are options of the options of walkie-talkies you can buy;

One radio works properly, the other can receive. I assume there are more than two by the question. Check and then rotate you batteries, mark on the working unit battery that it is GOOD. Transmit takes a great deal more power than receiving. Batteries, even un-used only last 18-24 months typically. If no joy, then check your programming but I think that is unlikely. It really sounds like a power/battery issue.

The kebt-650 appears to be a replacement batter for the Motorola Solutions MU and MT Talkabout walkie talkie series.

Program your existing walkie talkie to a common frequency with no PL code turned on and listen for activity. If you are using a TalkAbout or other FRS radio you should hear activity on one or more channels if you are in a city.
Best regards.

You will find the manual here. The radio is part of the 280 series radios, so there is a general manual on all in that series.
