The weight capacity of hydraulic air bottle jacks is the amount of weight that a bottle jack can lift and is measured in tons; it often comes in different weight capacities. But what’s the best weight capacity to choose for you? You should use a jack that corresponds to the most common weight ranges of the vehicles that you work on. For example, a 2-ton jack is capable of lifting most automobiles and small SUVs and a 3-ton jack can handle most trucks and full-size SUVs. Another great tip to consider before choosing yours is to know that bottle jacks support only 60% of vehicle weight, which means that a 2-ton bottle jack can lift a 3-ton car.
Bottle Jack Lifting Range
The next thing to think about is the bottle jack lift height because if it can’t get your vehicle off the ground, your new jack will be useless. Whether you only need it for tire changes or for repairs; in any case, you’ll need to compare the strokes and maximum height for the bottle jack by looking at the number of steps on the piston. Usually, the more steps, the higher the stroke will lift the tool. It is also very common for bottle jacks to have a lifting range from 9 to 18 inches.
Material and Quality
Another important factor is the material used for engineering the bottle jack. Both the body and the base of the bottle jack should be made from durable and sturdy steel so your tool withstands the pressure from lifting and holding weight for a period of time. A good quality bottle jack is made of a combination of drop-forged high-quality iron and alloy steel. Also, pay attention to the quality of welds to give the best strength and performance.

Hydraulic or Pneumatic
Is one better type than the other? While the hydraulic system is capable of lifting heavier loads, the pneumatic system significantly reduces lifting times. Thanks to the benefits of each type, many brands offer a combination of both (pneumatic air hydraulic jack). However, whether your bottler jack only has one type of system or a mix of both, all types are suitable for most applications.
Ease of use
Last but not least, consider how easy and comfortable it is to use the bottle jack. One thing to pay attention to is the handle so make sure that your tool comes with a long pumping handle that makes pumping more comfortable and easy to use.
