![]() ![]() I turned a maybe $500+ navigation update into a $250 one by getting the instructions and going to the parts department and asking politely if they'd allow me to install it on my own vs pay a technician hourly to babysit as the car downloaded the USB. Stories here are along the lines of "I bricked my smart", not "my smart broke down". It's just like the story of a lady (assumedly not knowledgeable in car service) gets ripped off, vs the less likely male, we are being taken advantage of when we don't know the proper procedure. #Varta car battery indicator software#You can ask your mechanic to measure its health when you visit for an oil or tire change.Click to expand.Do you mean different software versions, because I can't see how it would affect different ones differently otherwise? So some are programmed to self destruct while others aren't? Still points to some kind of failure.Įssentially my point is this, empowered with the actual (updated) Mercedes/Smart service literature, we can know whether we or the car is to blame. We recommend choosing a new one from a premium manufacturer like Varta, Bosch, Exide, Optima, ACDelco, or DieHard, just to name a few, and always make sure to check the warranty information.įinally, to avoid being stranded with a depleted battery, we also recommend checking it at least once a year. That's because it will have to deal with many more cold starts than it was usually designed to withstand. ![]() Never replace an old battery with one that has a lower CCA rating, and if you live in a cold climate, you want to buy one that has a higher rating. It refers to the number of amps it can deliver at 0☏ (-17 C) for 30 seconds while maintaining the required voltage. Cold Cranking Amps (CCA) This rating is used to describe a battery's ability to start an engine during cold temperatures. You can find these ratings on the label, and it’s important to choose a new battery that has the same or higher values. It is the power that it can deliver constantly for 20 hours at 80 degrees F (26 C) without falling below the 10.5-volt minimum. It indicates how many minutes it can deliver a constant current of 25 amps at 80 degrees F (26 C) without dropping below the minimum voltage necessary to keep the vehicle running.Īmp Hour (AH) or C20 indicates the amount of energy stored in a battery. Reserve Capacity and Amp per Hour (C20) Ratings The RC indicator refers to the extent of time that the battery can run without the help of the alternator before it discharges. Be sure to check the old one and remember its exact position before you buy a new one. ![]() In most vehicles, it is located on the right side, but others can have a reverse terminal, meaning that the positive is placed on the left. However, vehicles equipped with a start-stop function require a gel or absorbed glass mat (AGM) battery to cope with the significantly higher number of engine restarts.Īnother extremely important factor is the position of the positive terminal. Conventional engines can use a regular lead-acid unit, which delivers a large burst of power for a short time as needed for normal engine starting. Vehicles use different types of starting batteries. ![]()
