Battery Compartment Enclosures

Plastic enclosures with a battery compartment are molded from flame-retardant ABS plastic and are designed for indoor electronic applications. Lightweight enclosures with battery compartments are available in a variety of sizes and styles. A 2AA battery compartment is available on both the VK Series and VM Series enclosures, while a 9V battery compartment is available on the VM Series. Optional 20mm coin cell battery holders are also available for use in our key fob case styles. Project boxes with battery compartments are commonly used for measuring instruments, controllers, network devices, RFID tags and more.

What Is a Battery Compartment on an Enclosure?

Many types of handheld electronic devices use removable batteries such as alkaline batteries, non-rechargeable lithium batteries or nickel-metal hydride (NiMH) batteries. Since it’s easier to specify an enclosure with a built-in feature from the beginning than to have it custom-made later, many manufacturers choose handheld enclosure models with integrated battery boxes for their handheld devices.

A battery compartment typically includes cutouts and standoffs to hold the battery in place and accommodate its contacts. Some models also include the battery contacts themselves and a battery door for the compartment. This helps keep the battery safely connected at all times while protecting it from exposure to corrosive substances and other environmental hazards.

Which Type of Battery Compartment Enclosure Do I Need?

  • Form Factor: Polycase’s battery compartment enclosures offer designs suitable for many different kinds of handheld devices. Whether you prefer the simplicity of the VK Series, the tapered design of the VM Series or the compact performance of our key fob enclosures, we’ve got a form factor that fits your application.
  • Material: It’s crucial to choose an enclosure made from a durable material. At Polycase, we make our handheld enclosures from rugged ABS plastic. This tough and cost-effective material is the industry standard for all kinds of small electronics enclosures, and our ABS enclosures even offer UL 94 flame resistance, thanks to the material’s naturally flame-retardant qualities.
