What is a Maintenance Battery?
2 Answers
Maintenance batteries are refurbished batteries by manufacturers. Here are the specific details: 1. Nature: Maintenance batteries refer to recycled, repaired, and reused batteries (lower grade), commonly known as refurbished batteries. 2. Warranty: The warranty for maintenance batteries typically ranges from 12 to 15 months. If the battery has quality issues, the manufacturer will replace it with another set of maintenance batteries. 3. Quality: The quality of maintenance batteries is inferior to that of regular batteries because maintenance batteries themselves are batteries that have been repaired during the second stage of failure. The lead content is no longer purified, which naturally affects the battery's performance.
Maintaining the battery refers to the old-fashioned lead-acid type that requires manual care, the kind with removable caps on top. My car has used this type of battery for ten years, and every three months, I have to pop the hood to check the fluid level. If the electrolyte drops below the minimum mark, I have to top it up with distilled water. The terminals often get corroded with a white frost-like buildup, so I clean them with baking soda solution and a wire brush—otherwise, the car won’t start. Especially during cold winter starts, poor maintenance is the quickest way to end up stranded. The lifespan of these batteries depends entirely on upkeep; diligent care can stretch it to five or six years, but you must be careful not to let dirt fall into the refill ports.
