GM 24288531 Battery Assembly, High Vltg

It has a protective cover that has to be unscrewed in order to get access to the battery and the terminals. Regular check up of the battery of the vehicle that will provide quick start up is so advisable and right equipment must always be used while handling the battery. The measures include offing the ignition key, and all electrical loads, and the removal of the battery terminal clamp. The battery generates flammable hydrogen gas; do not take any spark producing items, cigarette, or even light a matchstick near the battery and ensure it is charged in a well-ventilated region. Electrolyte consists of corrosive sulfuric acid and thus requires protective safety glasses and protecting skin, eyes, as well mouth from direct contact with the solution. Less intrusive conditions involve checking the battery exterior and making sure that the positive terminal and cable clamps have no sign of damage, corrosion or cracks. If there is signs corrosion, it is necessary to remove the battery for cleaning with the best precaution of disconnecting the ground cable. Using safety goggles and gloves, the cable ends and terminals with warm water and baking soda, and all cleaned area should be washed with water. Check various specifications on the battery tray for their condition, and make sure that the hold-down clamp is tightened as much as necessary, but is not overtightened. Any part that is made of metal deformed by corrosion should be recoated with zinc based primer and later painted. For charging it is most advisable to disconnect the battery from the vehicle to avoid damage of the paint due to leaking gas while slow charge rate is recommended when charging a discharged battery. One or two-amp charger is safe, three to five amps are average and anything higher than five amps should not cause more than 1/10th the amp/hour of the battery. Even if you are using a trickle charger the average charge time generally takes 12 to 16 hours. If fitted with cell caps, unscrew and cover the holes, if not, skip this step, remove the negative cable and ensure that the charger cables connect to the terminals correctly, before connecting the charger. Warning light for overcharging battery should be kept an eye on if a high rate charger is used while a trickle charger is left to work overnight once initial tests are made. The specific gravity of the electrolyte during charging should be measured during the last hours with a hydrometer and the battery considered fully charged when the reading ceases to rise and gassing begins. Sealed batteries with an accurate readout of charge include some sealed batteries with hydrometers, you can check most sealed batteries via a digital multimeter, a fully charged battery should hover around 12.5 volts or more.

Battery straps and handlers.

It is important to remove the key from the ignition before disconnecting the battery to prevent it from getting locked inside the vehicle if the power door locks engage accidentally when the battery is reconnected.
