Battery Technology


Once a battery prototype has been developed, the final stage is to certify that product for use, from both safety and performance perspectives. Accutronics normally manages the entire approval process on behalf of its customers. Each battery design undergoes the appropriate safety testing from, for example, the IEC (International Electrotechnical Commission), the UL (Underwriters Laboratories), as well as the IATA (International Air Transportation Authority) and military standards testing from MIL (The US Department of Defence Test Method Standard for Environmental Engineering Considerations and Laboratory Tests), if relevant.


Coming back to my original hypotheses, it becomes clear why the battery is the very heart of many military, medical and industrial electronic devices. We might also argue that it is the quality of the design process which ensures the heart will continue to beat during the lifespan of the OEM’s device. As long as this happens and the battery provides power in an efficient and precisely monitored way, the device itself will do the rest.

military use, you may only make a couple of hundred units a year. If, to help cut costs, you opt for a battery intended for a consumer DVD player, you put yourself in very serious danger of being sent a last order notice from your supplier sooner than you might expect! If the original battery manufacturer stops making the product, you will be faced with a situation in which the only way you can get spare batteries is by reverse engineering your own!


This is a particular issue for medical and military products, which usually have a long life cycle, frequently spanning more


than a decade. Because of this, a good cell manufacturer will always work closely with the customer, and possibly the end user, to design cells that have a clear road map to guide the OEM through the future availability of the product. This means that even if new technology renders the original plan obsolete, the manufacturer would still be able to provide the battery or an exact equivalent, and it will still work to the customer’s specification.


Simply choosing a customised industrial


or professional battery, designed with your application in mind, guarantees you a lifetime of support.
