The life of the battery has deteriorated to the point it last a coupe of weeks. Is there a way to determine if the battery needs to be replaced?
Most electronic devices’ batteries will last anywhere from 3 - 5 years depending on usage and environment. It can of course last longer but that’s a decent average.
You battery will start to fail and you won’t be able to charge it seems to be the most prevalent way to know.
My doorbell battery lasts about 2-3 months before it needs recharging. It never occurred to me that I would have to maintain this device!! A total pain.
If you don’t provide enough electricity to keep the battery charged or a solar charger, what would you expect? Battery charges don’t last forever.
