California Proposition 65 Warning: Batteries, battery posts, terminals and related accessories contain lead and lead compounds, and other chemicals known to the state of California to cause cancer, birth defects and reproductive harm.
Before removing old battery, mark the positive (+) and negative (-) cables for proper connection to the new battery.
Always disconnect the ground cable first [usually negative (-)] to avoid any sparking around battery. To avoid sparking and explosive gasses, be sure load tester is OFF and battery is disconnected before hook-up.
Set the tester for one-half the battery's 0°F cold crank rating and apply the load for 15 seconds. If the battery did not meet the required voltage and if it was not charged in Step 1, completely recharge the battery and repeat the test. Conductance uses the battery's response to a very small signal in an attempt to predict the effects of a much larger current.
If the tester says to replace a battery that was tested in the vehicle, repeat the testing after removing the cables and cleaning the posts. Maintenance-free, non-accessible batteries are designed to eliminate the need to add water. Prior to charging, read the manufacturer's instructions for proper charger hook-up and use. Warning: If the electrolyte is accessible, verify that plates are covered before beginning to charge. Continue charging and reduce the rate as needed until a two-hour period results in no increase in voltage or decrease in current. If violent gassing or spewing of electrolyte occurs, or the battery case feels hot to the touch, temporarily reduce or halt charging.

Side Terminal Charging Posts should be used to ensure the best testing and charging results for side terminal batteries. Always purchase a battery that has enough cranking power and reserve capacity to get the job done.
And heat can damage batteries by causing internal components to wear out quickly while also making engines difficult to start. Connect one end of positive (+) booster cable to positive (+) terminal of discharged battery, wired to starter or solenoid. Connect other end of positive (+) booster cable to positive (+) terminal of assisting battery. Connect one end of negative (-) booster cable to negative (-) terminal of assisting battery, wired to ground. Neutralize acid spills with a paste made of baking soda and water or large quantities of water.
If required, add additional electrolyte to bring all levels to the bottom of the vent wells.
Connect ground cable last.If side terminal connection, use a special side terminal torque tool to tighten side terminal cables to avoid damage.
A load test is the best way to determine if the battery is delivering adequate electrical performance. Use computer memory saver to retain the vehicle's electronic memory while the battery is disconnected. Yet the volume of electrolyte above plates may eventually become depleted due to abnormal conditions such as high heat or improper regulator setting.
Charging a Gel or AGM battery on a typical shop charger - even one time - may greatly shorten its life.

They do not provide the necessary lead-to-lead contact, and can reduce your cold cranking amperage (CCA) and state of charge readings. Consider the vehicle manufacturer's recommended capacity to be a minimum-capacity guideline. Not only does cold rob batteries of power, it also stiffens motor oil making engines harder to start.
If the battery is known to be discharged or if the tester tells the operator to charge before testing again, the battery must be completely recharged.
Batteries should be boost charged if the open circuit voltage (voltmeter) reading is below 12.4 volts. A vehicle that has a lot of electrical accessories such as on-board computers, air conditioning, two way radios, etc. To avoid creating sparks, always turn charging and testing equipment off before attaching or removing clamps. If the electrolyte level is too low to read with a hydrometer, add water and take the hydrometer reading the following day, after the vehicle has been driven and the water has had an opportunity to mix.
Excess electrolyte may be forced from an overfilled cell and cause corrosion on adjacent metal parts, reduce performance, and shorten life. In cold weather, do not fill cells with water and let stand without running engine or driving the vehicle long enough to allow water to mix with acid.
