We spent 26 hours on research, videography, and editing, to review the top choices for this wiki. No matter how well you take care of your car, there are some things you just can’t control. Eventually, its battery will stop holding a charge as well as it used to, but that doesn’t necessarily mean you should throw it away. These desulfators won’t bring it back to new condition, but they can help you get some extra life out of it and put off buying a new one for a while. When users buy our independently chosen editorial picks, we may earn commissions to support our work.
