The primary purpose of a standard automotive battery is to provide power to a vehicle’s starter. To start the engine, electricity from the battery is used to operate the starter motor and to provide current for the ignition system during engine cranking.

Moreover, the battery acts as an electrical shock absorber, protecting vital electrical components from burning out during high voltage/current output. Developments in automotive technology have resulted in more sophisticated pieces of equipment becoming regular fixtures in today’s vehicles. Since these gadgets continue to draw power even when the key is turned off, batteries have to deliver more power to serve the car’s requirements.

“RC” stands for Reserve Capacity and is a very useful industry rating (for consumers) that refers to a battery’s ability to maintain low amperage load for the automobile’s ignition, lights and other vital electrical equipment should the alternator fail.

“CA” stands for Cranking Amperes. This is the load discharged in amperes by which a new fully-charged battery at 0 degrees Celsius (32 degrees Fahrenheit) can continuously deliver for 30 seconds and maintain a terminal voltage equal to or higher than 1.20 volts per cell.

Since today’s vehicles are equipped with numerous advanced electrical gadgets, choosing the right battery can be a tough task. Original Equipment batteries are rated at the minimum required rating, since they are designed for cars with all the Original Electrical Equipment in place. It is best to install a battery of HIGHER CAPACITY (AH, CCA or CA, RC) if you have installed additional electrical accessories. This is to ensure a margin of safety and better battery performance. Should you decide to install a bigger and more powerful battery, please note the following tips when carrying out the installation:

1. Fit the battery first. Does the battery have a height clearance or fitting problem? If yes, do not proceed with the installation. Does the acid tray fit? If not, purchase a tray that will fit the battery. This is to protect your undertray from acid corrosion Does the battery hold down fit? If not, purchase a hold-down that will fasten the battery to the vehicle.

2. Check if the new battery’s gas exhaust vents directly face your car’s electronic module. Some designs have their exhaust gas vents located on different sides of the cover (for MF-sealed batteries). Vents with direct exhaust may damage your vehicle’s electronic control module.

3. Always consult a battery expert or technician first before attempting to install a battery.

The best way is to consult your vehicle owner’s manual. Your car dealer may also assist you in your car’s minimum battery/power requirement. The OMMC’s outlets and dealers are furnished with battery replacement manuals that specify the vehicle make, model and year along with the recommended OMMC battery size and capacity rating.

Note: Never use a battery with a capacity rating LOWER than what the vehicle manufacturer/Original Equipment recommends.

It is important to select a battery type that is consistent with your vehicle, its application, and your driving requirements or patterns. OMMC distributors will gladly help you make the right choice.

The warranty covers failure of the battery due to material and/or workmanship for the duration of the warranty period. Just present your original guarantee certificate and sales invoice to facilitate replacement. If the battery fails within the warrantable period, OMMC thru its dealers will replace it with a new battery at no cost.

Being maintenance-free eliminates the need to add water and minimizes corrosion in the battery terminal posts.

A battery’s life varies according to the type of your vehicle, its application, and your driving requirements/patterns. You should take all of these factors into consideration when purchasing a battery. If you want better performance from your succeeding battery, consider upgrading to a battery with a higher RC rating than that specified by your car manufacturer.

Key-off electrical loads are common. The vehicle’s electrical system is adjusted to accommodate this extra drain. Nevertheless, if a car is equipped with devices that require power even after the key has been turned off, care must be taken during extended periods of vehicle inactivity or frequent short trips, since these do not allow the battery to recharge after the drain resulting from starting the engine. If a vehicle is used for short trips only and its electrical system is in good working condition, periodic recharging is required.
