Batteries have been around since the 19th century, when John Daniell invented the wet-cell battery. Daniell would likely be startled by the variety and sophistication of batteries in our day. Rechargeable batteries were one big step forward. The two incarnations therein – flooded and sealed rechargeable batteries – both have their advantages in applications ranging from vehicles to power supply grids. About Rechargeable Lead-Acid Batteries Rechargeable batteries were invented just...Continue Reading
Battery room hazards include; electrical, chemical, fire, respiratory, ergonomic, and sheer weight of the battery jars. Addressing each of these concerns is critical to battery room safety. In-house maintenance personnel, AC electricians and fly-by-night battery installers often do not have the training, experience, and correct tools to work with these systems according to published battery room safety standards. It is for this reason that using a professional company that specializes...Continue Reading
Thermal Runaway occurs most often in a valve regulated acid (VRLA) battery when the rate of internal heat generation exceeds the rate at which the heat can be expelled. If this condition continues for an extended period, the VRLA battery temperature will increase until the cells dry out and the container softens, breaks and melts. If your VRLA battery experiences thermal runaway, the heat it generates will destroy it. While...Continue Reading
[bra_dropcaps style=”dropcap2″]W[/bra_dropcaps]hen battery manufacturer Power Battery became defunct in 2011, it created a large void in the front terminal battery replacement business. Power Battery’s SLF12-205 and SLF12-250 ratings far surpassed any competition at the time. Recently, EnerSys came out with a replacement for the SLF line, the EnerSys version is the 12HX680F-FR. A valve-regulated, lead-acid (VRLA) battery, the DataSafe 12HX680F-FR is a 12-volt, 680-WPC model which enables coverage of a...Continue Reading
[bra_blockquote align=”right”] Lead acid batteries are designed to deliver a maximum number of discharge/recharge cycles before reaching end of life at which point the battery must be replaced. [/bra_blockquote][bra_dropcaps style=”dropcap1″]B[/bra_dropcaps]atteries have a limited service life, usually showing a slow decline in capacity until they reach approximately 80 percent of their original rated capacity, which is followed by a fairly rapid decline. There are five primary factors that affect UPS battery...Continue Reading
