How Many Years Does a BMW Car Battery Generally Last?
1 Answers
The original car battery has a service life of 3 to 4 years, while ordinary car batteries generally last 2-3 years. Below are specific classifications of car batteries (also known as storage batteries): 1. Ordinary Battery: The plates of an ordinary battery are composed of lead and lead oxide, with the electrolyte being an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost; the disadvantages are low specific energy (i.e., the amount of electrical energy stored per kilogram of battery), short service life, and frequent daily maintenance. 2. Dry-charged Battery: Its full name is dry-charged lead-acid battery. Its main feature is that the negative plate has a high capacity for storing electricity. In a completely dry state, it can preserve the obtained charge for up to two years. When in use, you only need to add the electrolyte and wait for 20-30 minutes before it can be used. 3. Maintenance-free Battery: Due to its structural advantages, maintenance-free batteries consume very little electrolyte and basically do not require the addition of distilled water during their service life. They also feature resistance to vibration, high temperature, small size, and low self-discharge. The service life is generally twice that of ordinary batteries.
