INFORMATION ABOUT BATTERY

	Battery Information
13	Charging
	a. Life Saving Charge
	b. Bulk Charge
	c. Absorption Charge
	d. Float / Trickle Charging Mode
14	Cleaning
	Check that all vent caps are tightly in place.
	Clean the battery top with a cloth or a brush and a solution of baking soda and water.
	When cleaning do not allow any cleaning solution, or other foreign matter to enter it.
	Rinse with water and dry with a clean cloth.
	Clean battery terminals and the inside of clamps using sandpaper. (Clean terminals will have a bright metallic shine).
	Reconnect clamps to the terminals and thinly coat them with petroleum jelly (Vaseline)
	This prevents corrosion.
	Keep the area around batteries clean and dry.
15	Battery Ratings and Their Meanings
	battery rating is the AMP-HOUR RATING
	unit of measurement for battery capacity, obtained by multiplying a current flow in amperes by the time in hours of discharge.
	Example: A battery which delivers 5 amperes for 20 hours is said to be of 100 ampere-hours or 100AH.
16	Battery Connections
	Series Connection
	Parallel Connection
17	Common Power Problems
	Power failure — Total loss of utility power: Causes electrical equipment to stop working.
	Voltage sag — Transient (short term) under-voltage: Causes flickering of lights.
	Voltage spike — Transient (short term) over-voltage i.e. spike or peak: Causes wear or acute damage to electronic equipment.
	Under-voltage (brownout) — Low line voltage for an extended period of time: Causes overheating in motors.
	Over-voltage — Increased voltage for an extended period of time: Causes light bulbs to fail.
	Line noise — Distortions superimposed on the power waveform: Causes electro magnetic interference.
	Frequency variation — Deviation from the nominal frequency (50 or 60 Hz): Causes motors to increase or decrease speed and line-driven clocks and timing devices to gain or lose time.
	Switching transient — Instantaneous undervoltage (notch) in the range of nanoseconds: May cause erratic behavior in some equipment, memory loss, data error, data loss and component stress.
	Harmonic distortion — Multiples of power frequency superimposed on the power waveform: Causes excess heating in wiring and fuses.
