Problems with New Battery Technologies

Neil Oliver, Technical Marketing Manager, Accutronics

The humble battery is one of the unsung heroes of electronics. While it is capable of powering both commercial and critical devices, it is often overlooked and undervalued during the product design stages, often leading to a wide range of performance problems later in the product lifecycle.

One Pivotal Incident Inspired the Development of Longer Lasting Batteries for Land Mobile Radios

Curt Quinter, President and Chief Engineer
Impact Power Technologies

A San Antonio, Texas police officer was out on patrol when he suddenly found himself caught in a shootout and away from his vehicle.  He tried to call for backup only to discover that his 2-way radio battery had died and his spares were at the station.  The officer was killed in the line of duty, but this kind of tragic loss should never happen.

Battery Backup Thermal Runaway Fears? Render it Harmless Through Continuous Monitoring

Tom Shannon, Director of Business Development • BatteryDAQ, Inc.

Thermal runaway is the disaster no one saw coming until it is too late.  It sounds like a horror movie, and it could well be, if batteries are not properly maintained. Every article on the subject will point out something like “If the design of the battery, coupled with the installation location, allows for proper dissipation of increased battery temperatures, thermal runaway is unlikely”.

The True Cost of a Battery

Tom Shannon, Director of Business Development • BatteryDAQ, Inc.

It is an established practice for design engineers to follow a process for selecting the best battery for a project or application, by submitting the choices through a balanced approach that compared technical requirements and goals, to cost and ongoing maintenance requirements. Continue reading

“Continuous Battery Monitoring is not Cost Effective.” – Pshaw!

The Changing Regulations Pertaining to the Transportation of Lithium Batteries

Robert Alverson, CHMM

In August the US Department of Transportation (DOT) issued final rule HM-224F affecting the safe transport of lithium batteries[1].  DOT announced that the effects from the revisions of HM-224F will “strengthen safety conditions for the shipment of lithium cells and batteries. These changes, some of which focus specifically on shipments by air, will better ensure that lithium cells and batteries are able to withstand normal transportation conditions and are packaged to reduce the possibility of damage that could lead to an unsafe situation[2].” Continue reading

Battery and Capacitor Replacement Keeps Backup Power Equipment in Good Health

Scott Baer, Marketing Manager-Batteries • Emerson Network Power, Liebert Services

Under the best of conditions, all batteries have a limited life expectancy, dictated by the frequency of battery discharge and recharge. Valve-regulated lead-acid (VRLA) batteries with a five-year design life start to lose capacity or fail within three to five years, and this aging process can be accelerated by any number of factors, including high or improper ambient temperatures, high or low charge voltage, overcharging and over cycling, loose connections and strained battery terminals.
