Why are batteries cylindrical?

A: The cylindrical batteries are composed of a hard cylindrical metal case, ensuring rigid mechanical safety and standardization in manufacturing,in result of fast production and low cost.

What is the difference between cylindrical and prismatic battery cells?

A: Below is the major difference between cylindrical and prismatic battery cells.
Case Difference
For cylindrical batteries, the case is cylindrical in shape and nickel-plated steel, while the prismatic battery cell is prismatic in shape and aluminum or stainless steel.

Size Difference
Li-ion cylindrical battery​ is standard size in 18500, 18650, 21700, while prismatic battery is customized in any different size and can reach much higher capacity.

What cylindrical rechargeable lithium ion battery​ models do you have?

A:We have 10443,14430, 14500,16310,18500,18620,18650,21700, 22650,22430, 26350, 26650,32700. While 18650,21700 are the most common and typical cylindrical battery models.

Are cylindrical 9v batteries the same as boxy​?

A: Boxy 9V and cylindrical 9V batteries are totally different.
Chemistry Difference
Boxy 9V contains alkaline or zinc AAAA cells in a 6 configuration or a single 9V lithium chemistry cell. Its voltage drops gradually.

Cylindrical 9V is Li-MnO2 or Li-Soc2 chemistry with 9V output, which even provides stable voltage until the end of life.

2. Application Difference
Boxy 9V battery is widely used for low-current, long-shelf-life applications in smoke detectors, guitar pedals, and transistor radios.
Cylindrical 9V battery is used for high power consumption applications in a wide temperature range,such as medical devices, security sensors, military radios, and industrial instruments.

3. Terminal Difference
Boxy 9V batteries are provided with snap connectors.
Cylindrical 9V batteries are in wired connections to plug into the devices directly.

Which is an automotive grade lithium cylindrical battery​?

A:4680 cylindrical battery is the automotive grad lithium cylindrical battery, which is widely used in Tesla’s EV.
