I don't. But I'd start by measuring the dimensions and looking for a battery
with similar ratings that will fit in the opening. They're quite common in
alarm systems and such as well as motorcycles/scooters. Lots of charts
available online, including at

The voltage (and preferably the construction if you can figure out what it is)
should match, but more amp-hours (Ah) is fine.
