What to know before buying

Listing details to confirm

Listing details are inconsistent: the title and feature copy claim 6000A and up to 10L gas/8L diesel, while the details field gives a battery capacity of 6000 amp_hours and another amperage field of 6000 A. The capacity unit and relationship between these figures are not clarified. Confirm the intended capacity and vehicle compatibility before relying on them. The stated temperature range and force-start operation are claims, not verified performance guarantees.
