Toyota 28800-03044 Battery

You can Select Your Vehicle to check if 28800-03044 fits your vehicle.

Disconnect the negative battery cable, then the positive cable from the battery. If the radio in your vehicle is equipped with an anti-theft system, make sure you have the correct activation code before disconnecting the battery. Check the battery state of charge. Visually inspect the indicator eye on the top of the battery; if the indicator eye is black in color charge the battery. Next perform an open voltage circuit test using a digital voltmeter. The battery's surface charge must be removed before accurate voltage measurements can be made. Turn On the high beams for ten seconds, then turn them off, let the vehicle stand for two minutes. Perform a battery load test. An accurate check of the battery condition can only be performed with a load tester. This test evaluates the ability of the battery to operate the starter and other accessories during periods of heavy amperage draw. Install a special battery load testing tool onto the terminals. Load test the battery according to the manufacturer's instructions for the particular tool. Disconnect the negative battery cable, then the positive cable from the battery. 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. 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 to prevent the battery tray from further corrosion. If you are replacing the battery, make sure you get one that's identical, with the same dimensions, amperage rating, cold cranking rating, etc. Installation is the reverse of removal.

First of all, the battery produces flammable hydrogen gas, so avoid sparks and charge it in a ventilated area. Check the battery's external condition for damage, corrosion, or loose connections. Reinstall the battery, install treated felt washers near the terminals.

To ensure the batteries remain in good condition, use safety gear such as goggles, gloves, baking soda, petroleum jelly, and a battery cleaner. Start by switching off the engine and removing its negative terminal. Avoid any sparks or flames near the battery since it produces highly flammable hydrogen gas. Charge the accumulator in a well-ventilated room away from sulfuric acid which corrodes everything it comes into contact with. Inspect for any corrosion on the battery, loose connections or cracks. In case of corroded areas, clean using baking soda solution. Also, check the bolts for the clamp that holds down batteries in their tray. Prepare rusted metals before painting them anew for instance corroded parts of your car's battery carrier and clamp should be primed and painted once they are removed from service for recharging purposes. Take out your batteries before charging them to avoid spoiling paintwork with acid drips or splashes. Always charge slowly and do not use rapid chargers under any circumstances. When charging is taking place remember to remove cell caps first then disconnect the negative cable before plugging the charger and connecting its cables to appropriate terminals on a battery's body. Keep an eye on the battery so that you can prevent overheating. If you wish to find out whether it is completely charged or not then get help from a hydrometer or voltmeter. A fully charged battery measures 12.6 volts or higher than this reading when checked with hydrometer tool set at 25 degrees Celsius temperature.

Before starting, make sure you have the needed safety equipment. Also, turn off the engine and disconnect the negative terminal. Keep away any sparks or matches near the battery due to its flammable gas. Be cautious of the corrosive sulfuric acid in the electrolyte. Clamps with a battery brush and a solution of warm water and baking soda. Damaged parts should be painted with a zinc-based primer. Use a slow-rate charger for the battery. Avoid chargers with a higher amperage rating than 1/10th of the battery's amp/hour rating. If the battery has detachable cell caps, measure the gravity with a hydrometer.

It is important to disconnect the cable from the negative battery terminal first and hook it up last to avoid shorting the battery.

Cold temperatures will cause the minimum voltage requirements to drop slightly. Follow the chart given in the manufacturer's instructions to compensate for cold climates. The minimum load voltage for freezing temperatures (32 degrees F) should be approximately 9.1 volts.

Battery electrolyte contains poisonous and corrosive sulfuric acid, so you should avoid contact with eyes, skin, or clothes, and never ingest it. Protective safety glasses should be worn, and children should be kept away from the battery.

You should remove the key from the ignition when disconnecting the battery to prevent accidental locking of the power door locks when reconnecting the battery.

The average time to charge a battery is typically 12 to 16 hours.

You should have safety equipment such as a face shield or safety goggles, baking soda, petroleum jelly, battery post or cable cleaner, treated felt washers, a puller, and rubber gloves.

Start by removing the fasteners that secure it and set the cover aside.

The battery produces flammable and explosive hydrogen gas.

Start by removing the fasteners that secure it and set the cover aside.

You should have a face shield or safety goggles, baking soda, petroleum jelly, battery post or cable cleaner, treated felt washers, a puller, and rubber gloves for safety.

Use a digital voltmeter by touching the black probe to the negative terminal and the red probe to the positive terminal of the battery. A fully charged battery should read between 12.6 to 13.2 volts depending on the outside air temperature.

Clean the corrosion with a mixture of baking soda and water, flush with clean water, and dry thoroughly.

Perform a battery load test using a load tester available at most auto parts stores. This test evaluates the battery's ability to operate the starter and other accessories during periods of heavy amperage draw.

The first step is to disconnect the cable from the negative battery terminal.

It is advisable to remove the key from the ignition on vehicles with power door locks to prevent accidental engagement when reconnecting the battery.
