Lead-acid batteries are truly the power behind everyday life. They keep those systems we depend on—cars, boats, public transportation —running as we move through the day. However, perhaps even more important is the function these batteries play in those times when normal life is halted—such as during a blackout or brownout. In these situations, when all other power is cut, lead-acid batteries ensure our safety by providing necessary back-up power for everything from computers to hospital emergency lighting.
In a power outage, lead industrial batteries are what back up wireless and wired telephones and computer systems so that phones stay on no computer data is lost. They power the majority of mobile vehicles both on land and sea. Lead-acid batteries start and power vehicles, back up uninterruptible operations like hospitals, railroad signals, weapons systems, and air traffic controls, and help electric utilities shift loads among grids. On the water they start engines, back up critical systems in submarines, and power navigational signals and devices in boats.
Life without lead-acid batteries would mean everything but muscle-powered transportation would stop. There would be frequent power outages as electric utility companies couldn’t handle rapid fluctuations in the demand for electricity. Every major telephone company in the world uses lead-acid batteries as back up power, keeping telephone systems working during storms, power outages, and earthquakes. They also provide quiet, pollution-free emergency power for critical operations in facilities like air traffic control towers, hospitals, railroad crossings, military installations, submarines, and weapons systems. Lead-acid batteries keep pollution control systems operating during blackouts and brownouts in environmentally sensitive manufacturing operations until the plant can be shut down. These batteries also back up cell phones and two-way radio systems.
Basic Usage Guidelines
Lead-acid batteries typically take 8 to 16 hours to charge and must always be stored in a charged state. Leaving these batteries in a discharged condition causes sulfation, a condition that makes it difficult if not impossible to charge.
Never let the open cell voltage drop significantly below 2.10 volts and be sure to apply a topping charge every six months or when recommended.
The optimum operating temperature for lead-acid batteries is 25 degrees Celsius. It is important to be aware of temperature when using and storing lead-acid batteries for every 8 degrees Celsius rise in temperature will cut the battery life in half.
