Short answer.... no, but people will blame the battery as being cheaper these days anyways.drumultaberei wrote: ↑Aug 17th, 2018 4:32 pmMy original battery died after 5 years on my Acura RDX, which was a big surprise for me. I previously had a 2002 Toyota Camry and the dealer recommended to change the battery after 9 years as the winter was coming, but I know someone that changed the battery after 12 years.
Was the Acura a poor quality battery or this is the norm nowadays?
Long answer.... still no. Car batteries have been around since drivers didn't have to crank their cars to start them so there are very few surprises or advancements (or reductions as the case may be) to make the batteries lighter or cheaper that basically hasn't been done, or isn't being done in the past 50 years.
What has happened is the cars have changed. Not only are cars drawing more power, many of the newer/newish cars, in an effort to save gas, are starting to not charge the battery like they did in the past (ie a dumb charger that keeps charging the battery at all times regardless of the condition of the battery or the load on the engine). The latest thought process is for the car not charge the battery all of the time and in fact use the charge in the battery during normal operation of the car and turn the alternator OFF during these times in an effort to lower the load on the engine. In theory, this makes sense from a fuel economy point of view as the lower the load, the better the fuel economy. The problem is that car batteries like to be fully charged all of time for maximum life but the newer/newish cars won't do that anymore. To add insult to injury, most cars will drain the car battery to much lower levels than they did before in an effort to keep that alternator off for as long as possible resulting in the battery developing sulphates in the battery which will reduce the battery's capacity and starting ability.
