Does anyone have a fix for the fact that these are notorious for overcharging the battery and thereby shorting the battery life. It appears there is no current limiting circuit? I am technical, has anyone come up with a design change that can be field added? Thanks

I have this radio (for 2 years) with the Li ion battery. I've never had a problem with over charging. There is a battery icon on the screen which goes away when the battery is fully charged. Make sure you use the wall power adapter that came with the radio. How many batteries have gone bad?

I had it one year and it went bad. I just installed a new battery from Amazon, the non-OEM one. I just felt the side of the radio where the battery is and it's cool. With the first battery it was rather warm. Maybe the first one was defective. We'll see how it goes with this one. Thanks for getting back to me
I've been monitoring the radio closely. The side of the radio is still cool. With the original battery it was always quite warm. Either the original battery was defective or this non-OEM battery from Amazon.com is better, and at half the price. We'll see how long the battery lasts, but as of now temperature wise the one from Amazon, the non-OEM one for about $20 is far far cooler. I don't use mine as a portable much, but we have a lot of power failures here, so I don't want to have to re-enter settings. As I mentioned before in searching and searching the internet people that don't use it much as a portable have said to unplug the radio once in awhile and let it run the battery down some to get better battery life. I also have the wall power adapter plugged into a really good surge protector. Anyway, this is what I've found. Hope it helps someone too!
The battery I have is also an after market one and it works great. It is not five years old and going strong.

if you are feeling uneasy, you can consider getting a wall switch with auto Shut-Off Timer,
monitor how long it takes to charge to full. and you can use it as a reference to set your timer. e.g. 100% take s 1 hour, 80 percent ard 48 mins ? etc...

The problem with this solution is that the radio normally runs using the AC adapter. It's in a standby state when it is "off" and stays connected to wifi where it get its signal. Turning off the AC will not only stop the battery charging but will actually run down the battery which is used as backup and will still drain because the radio is on standby.

Something like this will probably be the solution. I have no schematic for it otherwise I would design something. The problem in the design has probably been fixed in later models. Some people just unplug it for several hours and let the battery run down some and then recharge it. The real problem seems to be when it's left plugged in all the time. Thanks for getting back to me!!!

My Mondo radios ( I have 2) are normally warm on the upper right side. This has nothing to do with the battery or charging but is due to some electronics. I use the aftermarket battery in one of them and no battery in the other.
I wonder where the charging circuit is? I've never opened mine. I'm now suspecting the original battery was defective. It definitely got quite warm on the right side. With the aftermarket battery you're using, which is what I'm using now, that same area on the right side is quite cool. I'm just wondering if the charging circuit is on the right since since that is also where the power connector is. It seems to be working quite well now. I'll get back on how well the battery lasted months from now, or sooner if something happens. Thanks for your reply!!!
