Any battery that stands over 2 weeks in a discharged state commences "Sulphatiing".
We service these batteries with a "Sulphation Tester" (Free of Charge). The end result will determine if battery is serviceable or not.!!!
We also have full testing equipment to determine the following>>>
1) Load Testing
2) Output testing to all various ratings-SAE-DIN-ISO etc.
3) Battery Charging etc.
Up to 3 ton batteries are warranted for 2 years (unconditionally) Heavy duty batteries have a separate warrantee to international standards.
