How to Interpret Battery Model Numbers?

[DeJesse]

Generally, 12V indicates that the battery voltage is 12V; 70AH represents the battery's current value of 70A. Here is some relevant information about batteries: Working Principle: Batteries, also known as storage batteries, are a type of cell that converts chemical energy into electrical energy. Typically, the term 'battery' refers to lead-acid batteries. These are primarily made from lead and its oxides, with a sulfuric acid solution serving as the electrolyte. Lifespan: The normal lifespan ranges from 1 to 8 years, depending largely on the vehicle's condition. If the vehicle's alternator charges normally and there are no electrical leaks or grounding issues, the battery can generally last more than 3 years. If you notice that the battery isn't holding a charge, the starter is weak, or the headlights are significantly dimmer, the battery should be removed and charged for 12-24 hours using a charger. If this doesn't resolve the issue and the vehicle's mileage exceeds 50,000 km with no alternator problems, it may be time to consider replacing the battery.
