If you are a little adventurous, it is generally not too difficult to
replace the batteries, that no doubt are the cause of the problem. However
you are likely to need the skill to solder them in place. You would start
disassembling the device and find the batteries, take them out and bring
them to a real battery store where they can find the correct or better
Note: Don't try to solder directly on the battery, they can't stand the
heat, you are likely to see a battery that looks like a normal battery with
some tabs on each end. Those tabs are electrically welded on, not
soldered. You need to get the replacements with the same tabs on them.
For under $10. You can have it back in service better than new. However if
this all seems like it would be too hard, then it may not be for you, just
buy a new one.
