Frequently Asked Questions

ME ONE battery is an electrochemical device that stores chemical energy and converts it into electrical throughout an electrochemical Kinetic reaction once connected to a load. There are two main classifications of batteries: Primary (non-rechargeable battery), Secondary (Rechargeable battery).

ME ONE battery is a perfect choice for your vehicle and indeed for the following functions:

  • Supplies electrical energy for the accessories when the engine is not running.
  • Supplies energy to the cranking motor and ignition system.
  • Intermittently supplies current for lights, radio, heater, and other accessories when electrical demands exceed generator output.
  • Stabilizes voltage in the electrical system.

The total electric load in nowadays vehicles is demanding in term of energy and the race toward powered vehicles evolve high powered batteries demand.

Stamped grid is the most critical component of your battery that provide energy to start your vehicle and it is the major component affecting the battery’s end of life.

  • 20 Hour Capacity Rating (C20): The amount of amp-hours a fully charged battery can deliver I20 current at 80 and maintain a terminal voltage of at least 10.5V for 20 hours.
  • Reserve Capacity (RC): The minimum number of minutes a fully charged battery at 77 can continuously discharged at 25A to a terminal voltage of at least 10.5V.
  • Cold Cranking Amps (CCA): The amount of current a fully charged battery can deliver at 0 for 30 seconds and maintain terminal voltage of at least 7.2V.

The following list shows the major factors that will affect the life of your vehicle’s battery. Excessive heat, vibrations, deep discharge, or wrong application shorten the life of your battery.

Heat

  • High battery operating temperature shorten battery life.
  • High temperatures increase the rate of grid corrosion and expansion.

Cycling

  • Deep discharge affects the performance and life of SLI batteries.
  • Battery life is shortened according to the number of times of repeated CHA/DCH cycling.

Vibration

  • Excessive vibration affects the internal elements and shortens the battery life.

Application

  • Using a non-adequate battery, installing additional accessories, a defective charging system, etc. will all affect the performance of the battery.
  • Check for signs of plastic box damage. In case of car accident, it is not accepted.
  • Check the status of battery posts. (Cracked, burnt, or tilted battery terminals are signs of abuse. For Example: reworked, melted due to a loose connection, dirty and corroded cables, charging system issues).
  • Check the status of the charge eye. (The white eye is not covered in the warranty).

Activate your warranty to benefit from the service guaranteed of the ME ONE premium product.

The battery testers show different results once connected to your battery. The table below provides the detailed interpretations of these results.
Result Detailed Interpretation Remarks
Good battery Return the battery to service (No replacement) —
Good – recharge Fully charge the battery and return it to service (No replacement) Good battery but has low SoC (recommended to charge)
Charge & reset Fully charge the battery and retest (if still showing same result, then replace the battery) “Failure to fully charge the battery before retesting may cause inaccurate results”
Replace battery Replace the battery and retest “A REPLACE BATTERY result may also mean a poor connection between the battery cables and the battery. After disconnecting the battery cables, retest the battery using the out-of-vehicle test before replacing it”
Bad cell – replace Replace the battery and retest —
Test impossible Replace the battery (if not abused) May appear with aged batteries

Top considerations when replacing a vehicle battery:

  • ALWAYS select the same GROUP SIZE recommended by the manufacturer or the OE battery came out with the vehicle.
  • Select the highest CCA (meet or exceed) and RC in that group size.
  • Failure to select the correct battery for such an application will result in poor battery performance (and sometimes the charging and starting systems as well).

Tips to maintaining a vehicle battery:

  • Make sure you have the correct battery (size and technology) for such an application.
  • Always check on the condition of the charging system if it provides the right voltage to the battery (typical output 13.5V – 14.5V).
  • Do not let the battery inactive for prolonged period (sulfation!), hence use it all the time.
  • Always keep the battery terminals clean and free from any corrosion.
  • Always ensure battery terminals cables are tightly connected.

State of charge is the amount of remaining energy inside a battery at a given time. It’s the remaining capacity inside the battery.

SoC is determined primarily by the amount of sulfate ions in the electrolyte.

  • By the open – circuit voltage (dependent only on electrolyte Sp.Gr.) using a multimeter.
  • By the electrolyte Sp.Gr. Using a density meter.
  • By the charge eye.
    – Green Dot: 65% or above SoC.
    – Dark Dot: Below 65% SoC.
    – Clear: Low level of electrolyte.
