What battery does the Mercedes-Benz E260 use?
2 Answers
The original battery for the Mercedes-Benz E260L is from the Varta brand. A battery, also known as an accumulator, works by converting chemical energy into electrical energy. Typically, the term 'battery' refers to a lead-acid battery, which mainly uses lead and its oxides as electrodes and a sulfuric acid solution as the electrolyte. Information about batteries is as follows: 1. Conventional Battery: The plates of a conventional battery are made of lead and lead oxides, with the electrolyte being an aqueous solution of sulfuric acid. Its main advantages are stable voltage and low cost; the disadvantages include low specific energy (the amount of electrical energy stored per kilogram of battery), short lifespan, and frequent maintenance. 2. Dry-Charged Battery: Its full name is a dry-charged lead-acid battery. The main feature is that the negative plate has a high capacity for storing electricity. In a completely dry state, it can retain the stored charge for up to two years. When in use, simply add the electrolyte, and it can be used after 20-30 minutes. 3. Maintenance-Free Battery: Due to its structural advantages, the maintenance-free battery consumes very little electrolyte and basically does not require the addition of distilled water during its lifespan. It also features shock resistance, high-temperature resistance, compact size, and low self-discharge. Its lifespan is generally twice that of a conventional battery.
As a long-time Mercedes-Benz owner, I've found that the E260 typically comes equipped with a 12-volt AGM start-stop battery, with a capacity ranging approximately between 70 to 90 ampere-hours, primarily around 80Ah. This battery is designed to support the vehicle's automatic start-stop function, as AGM batteries can efficiently discharge and recharge during frequent starts, offering greater durability compared to traditional lead-acid batteries. I recall when replacing my battery, the manual recommended using original specifications such as the H8 model AGM battery, with brands like Bosch or Varta commonly being compatible. If you accidentally use a regular battery, the start-stop system might trigger fault codes, affecting the driving experience. Additionally, battery life is significantly impacted by temperature, so remember to check it in advance during winter to avoid being stranded. It's advisable to replace it at an authorized service center, given the sensitivity of Mercedes-Benz's electrical systems—don't risk bigger problems to save a little money.
