2-year limited warranty-Onyx brand batteries are warranted to be
free from defects in materials and workmanship for a period of two

After the first full year of warranty coverage ONYX will provide
extended warranty coverage for another 12 months covering only
defects in materials and workmanship. Extended coverage is limited
and does not cover problems caused by abuse, misuse, and improper
maintenance, failure to follow instructions, ordinary wear, or use
