How long is the warranty for a battery replaced at a 4S store?

[JessicaMarie]

4S store replaced batteries come with a one-year warranty. Below are specific details about batteries: Definition: A battery is a type of cell, also known as a storage battery, which works by converting chemical energy into electrical energy. The term 'battery' commonly refers to lead-acid batteries, which primarily use lead and its oxides as electrodes and sulfuric acid solution as the electrolyte. Classification: Conventional batteries, where the plates are made of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. Their main advantages are stable voltage and low cost; disadvantages include low specific energy (the amount of electrical energy stored per kilogram of battery), short lifespan, and frequent maintenance. Dry-charged batteries, fully known as dry-charged lead-acid batteries, are characterized by the negative plate's high energy storage capacity. In a completely dry state, they can retain the stored charge for up to two years. To use, simply add the electrolyte and wait 20-30 minutes before operation.
