March 2019 / / Security Business 19 Case in Point Let's look at costs for a battery that might be used in a security applica- tion. I priced a 12 V 10 AH LFP bat- tery on Amazon at a little more than $150, and a 12 VDC, 4.5 AH LFP bat- tery for nearly $80. is compares to a decent lead acid battery at $15 to $20, and Lithium ion batteries at the same rating appear to be about $25. At more than 2,000 cycles, that brings the per-cycle cost for LFP to $.04 – 2.5 times less than a typical lead acid battery and half that of lithium ion. Altronix sales manager Ronnie Pennington says voltage declines from a lead acid battery as it discharges, thereby creating a possibility of having inade- quate voltage for the load and compromising operation. e LFP is more constant until it has nearly reached full discharge – resulting in 40-percent longer battery operation in a cycle. "A key initial market driver was maintenance cost for pole- mounted equipment where batteries may be difficult or time-consuming to access," Pennington explains. "(LFP) batteries should greatly reduce the number of calls to address dead or damaged batteries." Suppliers of LFP batteries say that certain sealed lead acid battery chargers may be used with LFP batteries, but may not produce a full charge, as the new LFP batteries require a slightly higher charging voltage (13.8V -14.4V vs. 13.2 for sealed lead acid). In February, Altronix intro- duced new versions of its Netway Spectrum PoE+ switches with a 12-48 VDC voltage "boost" feature to enable a sin- gle LFP battery to be used in lieu of four conventional bat- teries to power PoE equipment (please see www.securityinfowatch. com/21068290 for more info). Add all this to LFP's ability to source more power to nearly full dis- charge, to be recharged quickly and repeatedly, and at half the weight – the case for the battery's lifecycle cost savings becomes compelling. ■ » Ray Coulombe is Founder and Managing Director of SecuritySpecifiers and the CONSULT Technical Security Symposium.
