Subaru 82110AA010 Battery 55D23L Mf

To ensure that your vehicle starts quickly and reliably, you should have a routine preventive maintenance program for the battery. Prior to doing any work on your battery, ensure that you have the necessary tools to safely carry out these activities, such as safety glasses or a face shield; petroleum jelly; baking soda solution; treated felt; pullers; cleaning fluids for battery post and cable terminal connections and latex gloves. Precautions should always be observed when working on a battery like turning off the engine and accessories, disconnecting the cable from negative terminal as well as avoiding sparks, smoking or flames since hydrogen gas produced by the battery is highly flammable and explosive. In addition to this, if there is contact with eyes skin or clothes one must be careful because of poisonous and corrosive sulphuric acid in electrolyte remember wearing protective safety glasses. Externally examine the battery for signs of corrosion at positive terminal and cable clamp area tightly connected cables holding clamp cracks in casing or cover as well as hold down clamps being loose. If corrosion exists, loosen cable clamp bolts to remove the battery then slide it off terminals by disconnecting hold-down clamp. Thoroughly clean both sides of each cable clamp using a brush with a special cleaning fluid made from baking soda strictly avoiding entrance into the cell. Wear rubber gloves along with goggles while doing this then wash all cleaned areas using plain water only after cleaning terminals including top part of battry assembly which had been soiled during removal process. When reinstalling the battery, check tray together with hold-down clamp bolts ensuring no piece gets left behind in its respective position. Any corroded metal parts require priming them with zinc-based primer before painting them over again. A discharged storage cell can be restored by slow-rate charging using one or two-amp chargers or even maintain its charge whereas quick boost charges are meant for emergency situations only. Charge according to instructions given by charger, if provided take off cell caps, then plug holes using clean cloth to prevent electrolyte from splattering and finally connect charger cables to battery posts. During charging especially with higher-amp chargers check regularly to avoid overheating. Use a hydrometer or the built-in hydrometers or voltage readings to ascertain the charge state.

Before disconnecting the battery for service procedures, it is important to note that on a vehicle with power door locks, it is wise to remove the key from the ignition and keep it with you to avoid the possibility of it getting locked inside when the battery is reconnected. Devices known as "memory-savers" can be used to avoid some of these problems by providing sufficient current to maintain audio unit security codes, PCM memory, etc. To disconnect the battery, loosen the cable end bolt and disconnect the cable from the negative battery terminal, and isolate the cable end to prevent it from coming into accidental contact with the battery terminal.

Rapid and easy starting is possible only if your vehicle's battery has a routine preventive maintenance program. For any battery maintenance, make sure you are properly equipped to work around the battery safely. Take caution when handling the battery for example by turning off engine and all accessories and disconnecting the negative terminal cable. The hydrogen gas generated by the battery is explosive as well as flammable hence no sparking or lighting near it, ensure that it charges in a properly ventilated area. In addition to that also be wary of sulfuric acid which is poisonous and corrosive in the electrolyte by wearing protective safety glasses while keeping this away from eyes, skin and clothes. Check its external condition for any damage or loose connections, clean any corrosion on it using a brush made specifically for batteries and an aqueous solution of warm water mixed with baking soda thereafter. Ensure that the battery tray is in good condition and hold-down clamp bolts are tight enough not to move out of place so easily. Use a zinc based primer and paint if there are any corroded metallic parts . It is recommended that you remove a charging battery from your vehicle to prevent paint damage due to escaping gases. The best way to recharge a discharged battery or simply keep it charged up is through slow charging with one or two ampere charger units which have been specially designed for this purpose alone Avoid using high amperage chargers or rapid boost charges as they can stress the battery causing further untold harm towards it. When charging, all cell caps (if any) should be removed, holes covered with a clean piece of cloth, then charger cables clamped onto posts of the cells being loaded. During charging check regularly whether the cell getting too hot ,and if they have removable caps , test with hydrometer specific gravity . Some batteries having sealed tops contain built-in hydrometers/voltmeters that show their level of charge. A fully charged battery would read 12.6 volts or above.
