What to know before buying

Listing details to confirm

Listing details are contradictory: the title says 4000A, while the main feature claims 4000A and other details give the same figure as both amperage and peak output. Battery capacity is listed as 6000 Milliamp Hours in the technical details but 24000mAh in a highlight, and engine suitability is variously described as under 10 litres and 10L petrol/10L diesel. Confirm the exact capacity and your engine's compatibility before relying on it. The stated 1.3-hour recharge time is a manufacturer claim.
