What types of batteries can this battery booster start?

It can start 6.0 L gas/3.0 L diesel engines and other 12 V vehicles like motorcycles, cars, SUVs, pickups, or lawnmowers.

Why can't I get this jump starter fully recharged? Only stuck at a certain battery percentage?

This item is not fulfilled by seller and the battery inside will discharge itself constantly while being stored in the warehouse. Therefore it takes a longer time for the first time you charge this jump starter, which should be at least a few hours.

How often does it need to recharged?

It's best to recharge it within 3 months.

Why did the jump starter fail to jumpstart my truck in winter?

The battery may not perform optimally in extreme cold weather. Please ensure that the jump starter is kept in a warmer place before use.
