A new designer's guide for battery compartments for 2017. The guide contains design considerations for holders, battery hardware, contacts, materials and platings. There are reviews of ensuring reliable contact, human factors engineering, ANSI-IEC specifications, ventilation/gas absorption, and battery contact stability.
A battery holder is most commonly sold as an integral or removable compartment or cavity, designed to be inserted into - or attached onto - a suitable item of cell-powered equipment. The primary function of a battery holder is to keep cells fixed in place safely and securely while conveying power from the batteries to the device in question.
Types of Battery Holder Mounts. The way the battery holder is attached to the cell-powered device is known as the battery holder mount. The different types of battery mounts are: Panel Mount: A panel mount battery holder is a separate compartment designed to hold cells. It can be inserted into a cavity in the device that needs power.
Battery holders are often designed for a specific type of battery, but some holders can accommodate various batteries with different chemistries. However, it is important to consider that if a battery holder contains cells of different chemistries simultaneously, the power output will be limited by the weakest cell.
External connections on battery holders are most often made by contacts either with pins, surface mount feet, soldered lugs or via a set of wire leads. Battery holders are often designed to be incorporated within the body of an electrical item, but they’re also frequently sold as external compartments or attachments.
Battery holders may have a lid to retain and protect the batteries or may be sealed to prevent damage to circuitry and components from battery leakage. Coiled spring wire or flat tabs that press against the battery terminals are the two most common methods of making the electrical connection inside a holder.
A battery holder is one or more compartments or chambers for holding a battery. For dry cells, the holder must also make electrical contact with the battery terminals. For wet cells, cables are often connected to the battery terminals, as is found in automobiles or emergency lighting equipment. A battery holder is either a plastic case with the shape of the housing moulde…
