fered less from cold temperature . Unfortunately, NiCads suffer from their own shortcomings — short life spans, limited recharge life and a nasty habit of developing a charge “memory,” which would signal to a charging controller the battery was recharged to capacity while it was still well below the limit . Nickel-metal hydrides, which began replacing NiCads in many uses, exhibited less of a memory problem, but still needed regular

conditioning . They do perform slightly better as power sources . Li-ion — lithium ion — batteries are excellent at powering low-demand devices, such as portable phones, portable GPS units, iPads and iPods, and as backup power sources for aircraft . They can produce steady power for long periods of time, and they recharge almost as fast as they discharge — a distinct benefit for portable applications . The newer Li-ion technologies show no “memory” problems, have excellent use profiles and a high number of recharge potential . And one of them — lithium nanophosphate — improves on the high-load use without overheating . Mid-Continent Instruments tapped the lithium nanophosphate technology for its latest instrument backup battery . The Electrical Buddy System The lead-acid battery common to most airplanes works as part of the electrical system . Supplying sufficient electrical power for an aircraft’s components falls to the alternator, starter/generator or old-fashioned generator, which runs off the engine . The jobs of absorbing power fluctuations, serving as an electrical-system backup and providing engine-starting power all fall to the battery . But you can’t have one without the other, and it helps everyone and everything concerned if the electrical-generation capacity exceeds the load the aircraft can demand — with a right-sized battery sufficient in power to turn

Avionics shops should be able to help customers if they question whether or not their regulator matches up with their needs and the airplane’s charging system.

the engine to start it and absorb spikes in the output of the generating source, but as compact and low-maintenance as possible . Ideally, the partners both work seamlessly and pretty much invisibly — out of sight — as they do when everything works properly, keeping them out of mind as well . While they sit quietly working away back in the dark hollows of an airframe, batteries absorb considerable abuse in their largely unsung lives . They store their energy for an instant of high demand, then convert their chemical potential energy into enough electrical kinetic energy to spin an engine — and make the delivery at the speed of light . The main battery suffers the strains of battery drain for the duration of the start cycle . Like humans, batteries tend to work a little slower when the temperature drops . Meanwhile, the battery needs to convert electrical power back into the chemical energy poten-
