They are not permanently sealed, but are designated to be maintenance free. They can be oriented in any manner, unlike normal lead–acid batteries, which must be kept upright to avoid acid spills and to keep the plates' orientation vertical.
In other cases, battery packs are mounted externally and may serve a mechanical function, such as a handle or base for the product. At the same time the case must also protect the cells and the electronics from the harsh operating environments of temperature extremes, water ingress, humidity and vibration in which these batteries work.
In some designs, the battery pack can form part of the outer case of the end product and usually requires a mechanical latch to hold the battery in place. This latch as well as the terminals must interface with plastic parts from the device itself so high precision and tight tolerances are essential.
Achieving a quality seal is critical for the performance and longevity of EV batteries and for protecting integral components from water intrusion and other harsh environmental conditions. EV batteries are subject to increasingly stringent performance and safety standards.
The product cost can be reduced by using insert moldings in which the interconnection strips and the terminals are molded into the plastic parts to eliminate both materials and assembly costs. In some designs, the battery pack can form part of the outer case of the end product and usually requires a mechanical latch to hold the battery in place.
The simplest and least expensive packaging for small batteries is shrink wrap or vacuum formed plastic. These solutions are only possible if the battery is intended to be completely enclosed by the finished product. In other cases, battery packs are mounted externally and may serve a mechanical function, such as a handle or base for the product.

The electric car market is booming, so it is important to learn more about how the ''heart'' of an electric car, the lithium-ion battery pack, works. The battery pack is an intelligent device that stores and delivers energy via its modules equipped with lithium-ion cells. The battery production process is crucial to ensure optimal safety and ...
Enclosures made from injection molded plastics are most commonly used for battery packs. For these enclosed pack designs, two or more plastic parts are molded and then assembled with the pack and accompanied circuitry. They can be sealed using glue, mechanical fasteners (Screws) or ultrasonic welding. The product cost can be reduced by using ...

Properly sealing lithium-ion battery cases and covers is critical to overall battery performance, safety and quality. Automated dispensing applications for batteries must be precise to achieve full performance and to avoid dangerous moisture and gas leaks.
For example, some hybrid and start/stop vehicle batteries only need to be sealed to protect the lithium-ion battery cell, and the mechanical requirements for the casing are low. Larger batteries not only use more of the polymer, but may also use a compound that complements the metal matrix.
Nick Flaherty assesses the various materials and processes used to seal and protect a battery pack. Sealing a battery pack safely is a key requirement for e-mobility systems. While there may be concerns about the ingress of moisture or dirt, there are also issues over venting gasses and preventing electromagnetic interference.
