Free to a good home

Now for the catch. These have had light use but haven't been touched for at least a couple of years due to child duties and the fact I use my Exposure Diablo for night riding nowadays.
I took my Sister in Law out with them a couple of weeks ago after giving them a full charge and it died after 25 minutes.
I've given it a dozen or so charge/discharge cycles and it's no better.
If your one of the geeky electronics bods on here it may be a cheap fix.
