Deka batteries manual#
Mercedes-Benz models have specific instructions in the owner’s manual for electrical set up requirements, and a few Infiniti models even require the shift release to be reset after battery replacement. Several BMW, Audi, and Lexus vehicle models require the computer system to be reset after battery replacement. The impact of losing data collected by the vehicle can result from something as inconvenient as to failing an emission’s test (depending on the state of inspection) to something much more serious like damaging the battery due to incorrect voltage output settings. Once battery power is disconnected, those settings are cleared and the vehicle needs to relearn this data. As we progress into the 21st century, the stakes of not taking the proper precautions before and after disconnecting the battery have increasingly become much higher as well as the need for more sophisticated methods and a broader knowledge base for adhering to these precautions.įor example, for most modern vehicles, the engine’s computer records things like engine misfires and oxygen-sensor performance, and confirms that, over time, the emission-control system is doing its job. Mostly towards the end of the 1990’s, some of the biggest consequences to disconnecting the battery resulted in losing radio settings, seat positions, and side-view mirror adjustments. However, it’s the heat that does most of the damage, but more batteries actually fail when they’re put to the test in the cold. In general, extreme temperatures, hot or cold, have an adverse effect on battery life. However, in the cold, oil and transmission fluids are more viscous so getting the car started requires more energy. Higher temperatures also have a detrimental effect on battery life. Always pay close attention to the Battery Application Guide and specifically follow its instructions. Also, if the battery’s dimensions don’t align with the vehicle’s recommendations, it might not have a good fit and suffer damage from vibration or clearance issues. For instance, if the vehicle requires a certain amount of starting power, installing a battery that isn’t designed to provide that much starting power will quickly wear out to the point of a no-start situation. Draining the battery to a very low state-of-charge can do permanent capacity damage.Īnother common cause of battery failure is from putting the wrong battery in the wrong application. Always protect your eyes!Īccidental power drains (like leaving your headlights or dome lights on) that discharge the battery to the point that it doesn’t have enough power to start the vehicle. NOTE: Remember to always wear safety glasses and a face shield when working on or near batteries.

Conventional automotive batteries perform best when they are at a full state-of-charge. Batteries will self-discharge if not used.
