Although often referred to as disposable batteries, lithium batteries are highly recyclable. We suggest looking into local recycling programs or companies to see if there are any options. Lithium batteries typically are rated at 1.5 or 3.0 volts. The 1.5 volt version are direct replacements of alkaline primary batteries. 1.5 volt lithium batteries can be replaced with rechargable Ni-MH batteries. 3.0 volt lithium batteries can be replaced with special 3.0 volt Li-ion batteries.
