Until now, battery warranties in the market were typically limited to a maximum of 5 years. However, some companies have now introduced batteries with an impressive 20-year warranty. These batteries offer a full replacement warranty for the first 10 years, followed by a pro-rata warranty for the next 10 years. This means that if the battery fails within the first decade, it will be replaced free of charge. After 10 years, users can still get a replacement by paying a nominal fee.
