In cases where it is necessary to recharge a battery discharged for prolonged non-use, unintentional discharge or malfunctions to the car charging system, you should contact a specialized workshop (Jump Start Service in Singapore).
Alternatively, you can take care of the problem by respecting small precautions to preserve your own safety and battery integrity. Operating in a ventilated room, covered and away from flames and sparks, remove the battery from the car and connect the battery poles to the respective terminals of the charger. In addition, you should provide the battery with a maximum current corresponding to 10% of nominal capacity.
You should aim for a slow charge for a period of about 10 hours or until the absorbed current is reduced to values of a few mA and the voltage is about 13.5 V. It is not advisable to supply higher currents or fast charges that could speed up the process of sulphation to the plates.
If you plan a period of rest and prolonged use of the battery, you can connect it to a charge maintainer without necessarily removing it from the car. This allows you to maintain its efficiency and the charge unchanged over time. In this condition, it is assumed that the car must be stored in the garage for connection to the open bonnet or where it is provided via the 12 V socket of the passenger compartment.
The charge is maintained by supplying the battery with a constant voltage current of several thousand Amperes for the entire period of inactivity. The battery charging and maintenance operations can be carried out in complete safety, respecting the basic safety regulations.
Use fully automatic battery chargers capable of supplying current based on the nominal capacity and starting the charging procedure at the end of the charging procedure. maximum charge.
When the car battery replacement needed, you cannot do anything but replace it. The replacement is a very simple operation to perform, with suitable tools, which in the simplest cases are limited to some wrenches, and paying the utmost attention not to connect the two clamps with the tools causing a short circuit.
Here’s how to proceed. After having checked that the panel is off and no accessory is turned on, identify the battery position with the help of the manual (in cases where the arrangement is different from the usual location in the engine compartment).
Proceed with the removal of any plastic protections or upper and lower retaining brackets, trying to memorize the correct position of the components (taking a picture before dismantling in some cases can help a lot in the reassembly phase). Always disconnect the negative terminal first and then the positive one.
