tial that existed before engine start, a recharge process generally controlled and monitored by a regulator in the system . This process makes batteries warm . Regulators should match the system and the battery because overcharging is unwise, as is charging so quickly that the battery struggles to accept the load and overheats; the electrolyte could boil or the heat could damage the battery . In most airplanes, the main battery also must be ever ready and eager to work as a standby electrical supply in the event the generating source fails . The larger the battery’s storage capacity, the longer it can supply standby power — but you don’t want it to be too large lest it eat up payload and space needed for other things . And the lowly battery has to do these things while enduring extreme, rapid changes in altitude, temperature and atmospheric pressure . Matching Battery to System Technology aside, your aircraft’s electrical system needs two things: a supply source capable of meeting the needs of the airplane when everything is turned on, and a battery and regulator matched to the system . This supply source — alternator, generator and starter generator — should be able to meet the demand when you turn on all the lights, all the radios, all the electronics and all the portable stuff you plug into the old cigarettelighter socket . If the source can’t meet the full demand, every time you impose

this demand the regulator will start making up the difference by tapping power off the battery . The battery must be matched to the charging system, so the regulator doesn’t try to charge it too much, too little or too quickly . Plus, it should be powerful enough to give you time to use it as the sole source of electrical power in the event of a generating-source failure . Forty minutes of power is a good minimum to consider . 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 . Choosing a Battery: It’s Not So Simple Technology advances — sometimes only temporarily . Consider the lead-acid units still dominant today . Readily available, right sized, reasonably priced and familiar . It should be no surprise they remain popular . Thanks to a major advance in lead-acid battery technology, expect them to stay popular for a long time to come . In a way, this development, the hottest thing in lead-acid battery technology today at first blush seems like a step backward — back to lead-acid from the oncecutting-edge nickel cadmium battery in many aircraft applications . However, the old dog returned to the pack significantly improved and with benefits over older leadacid technology and the newer NiCad that displaced old lead acid in many applications . It’s called recombinant gas technology, or RG . Yes, it’s been
