MF battery (Maintenance Free Battery)
- Use lead calcium (CA / CA) and tin mixed with elements to prevent distilled water and high corrosion resistance.
- Use sulfuric acid with a specific gravity higher than about 1.260 - 1.280. SP.GR (STD) is able to store and supply power well with high performance.
- Fill the acid and charge with 100% complete from the factory. Use immediately. No need to add distilled water throughout the lifetime (Free Maintenance).
- Keep the power to start the engine for a long time. Although rarely use cars
- The barrier is a type of envelope (PE Separator) which is made of modern PE plastic with tear-resistant properties higher than glass-fiber baffles. Helps prevent dust-lead-chemical powder fall and will help preserve the structure of the sheet to last longer than ordinary batteries.
- The closed casing has a frame arrester, using a caramic filter to help prevent the evaporation of distilled water and prevent battery explosion.
- Contains Sulfate Stop to help prevent the formation of sulfates, resulting in longer service life
- The MF battery will emit about 20% of its current power per 1 month and depending on the temperature conditions, if the MF battery is stored for more than 4 months, the car will start to be difficult to mount. In order for the battery to be ready, always bring the battery to fully charge before use. (Wake up before use)
Note: You can add distilled water to the MF battery when you need it once a year or if the Electrolyte solution is lower than the lower level.
Normal battery (Conventional Battery)
- Use lead, antimony and silium to produce positive-negative plates
- Is a dry compressed sheet which charges about 70% of the capacity when adding acid to the battery Then charge for 2-4 hours to get 100% complete power
- Must always maintain the distilled water level (every 20 days or 3,000 kilometers per 1 time or according to usage conditions)
- When the current is completely discharged (DOD), it will have a high IR value and will be able to charge the power more difficult than Battery MF slightly.
- Use sulfuric acid with a specific gravity lower than about 1.240 - 1.260 (STD)
- The shelf life is longer than Battery MF because it is a dry battery that has not yet been added. If not activated, it can be stored for up to 5 years without affecting the quality.
- Have a lower price than MF batteries, but efficiency And the service life is similar to MF batteries
- Suitable for heavy-duty and high-temperature vehicles
- Refillable battery Will evaporate the electricity in itself about 0.5-1% per 1 day or 30% per 1 month and depending on the temperature (Meaning batteries that add acid and charge current)
