Nissan 24410-9B900 Battery

Anytime the battery is disconnected, stored operating parameters may be lost from the PCM causing the engine to run rough for sometime while the PCM relearns the information. A battery cannot be accurately tested until it is at or near a fully charged state. Disconnect the negative battery cable, then the positive cable from the battery and perform the following tests: Battery state of charge test, Open voltage circuit test, Battery load test, and Battery drain test. If you are replacing the battery, make sure you replace it with a battery with the identical dimensions, amperage rating, cold cranking rating, etc. Always disconnect the negative cable first and hook it up last or the battery may be shorted by the tool being used to loosen the cable clamps. Disconnect the negative battery cable, then the positive cable from the battery. Remove the battery hold-down clamp. Lift out the battery. Be careful - it's heavy. While the battery is out, inspect the battery tray for corrosion. If corrosion exists on the battery tray, detach the bolts and remove the tray from the engine compartment. Clean the deposits from the metal underneath the tray to prevent further corrosion. Installation is the reverse of removal.

It is very important to have proper equipment for safe handling An effective battery maintenance schedule is the basic requirement for maintaining dependable cranking power, therefore, a preventive maintenance program of the battery in your vehicle should be faithfully adhered to. Measures include switching off the engine and all the accessory systems in the vehicle as well as removing the negative terminal. The battery generates what is known as flammable hydrogen gas, therefore, it is recommended that charging is done in a well-ventilated environment, do not use this battery near any source of naked flame, sparks, or any sources of heat such as cigarettes or lighted matches. Electrolyte is composed of corrosive sulfuric acid so protective safety glasses must be worn and contaminated skin or eye or clothes should not be touched. Check the battery's exterior appearance and condition, concentrate on the positive terminal and the cable clamp does not possess any signs of corrosion, loose connections, or crack. If this is the case, the battery should be removed for cleaning; it is advisable to disconnect the ground cable first. Wash the cable clamps and the terminals with warm water with a little baking soda, while wearing safety goggles and gloves and rinse the cleaned parts with clear water. Make sure that the battery tray is in good condition and hold-down clamp bolts are properly tightened down, not overly tight though. For charging, it is advised to pull out the battery out of the car to avoid drawing spilled paint; the best method for charging a flat Battery is slow-rate charging. A one or two-amp charger is safest; two-amps is the maximum most retailers should use; anything over one-amp should be no more than 1/10 the amp/hour rating of the battery. Charging times differ, normally with trickle chargers it takes up to 12 to 16 hours for a battery to be charged fully. If there is a cell cap then remove all the cell caps, if there are holes then cover them with a cloth snugly connect the charger. Do not overcharge the battery especially in high current and observe and record specific gravity with hydrometer if the battery has removable vent caps. Battery with float charge should have no change in specific gravity for two hours and should bubble freely. The sealed batteries come with hydrometers built-in, or can be checked with a digital voltmeter; the fully charged battery is to be 12.6V or above.
