X-TREME XB-310Li Owner's Manual page 17

What's Inside Your XB-310Li Battery
The Battery is composed of four 3.7 Volt, 10 Amp-hour
capacity batteries, in series, for a total capacity of 25.9 V,
10 Ah.
The component batteries are a standard, commercially
available size. Keep this in mind, however, should you
choose to service your battery.
1) The batteries are soldered into place. Replacing
batteries will require soldering equipment and
skills.
2) Batteries can be extremely dangerous. If allowed
to short-circuit, they can cause burns, create
blinding arcs, or explode, causing serious injury. If
you accept this risk, work slowly, and exercise
utmost care! Work with only one wire at one time.
Battery Trouble
Should a battery ever leak, do not touch the battery
liquid. If you are exposed to the solution, flush the
affected area with water. If you must handle the battery,
wear disposable gloves.
Replace the battery if there are leaks, visible breaks or
cracks.
Dispose of used batteries by taking them to a recycling
center, or according to state and local laws.
