Kindle Battery Life. With proper care, you will not have to replace Kindle battery, which is a Lithium-Ion Polymer battery. Extensive use of the Kindle e-Reader can cause the length of time between charges to decrease. You must be aware of the best approach to maximizing the Kindle battery life.
I have had to replace the battery several times through out it's life. It has been 9 years and it still works as well as the day I got it. My kindle has seen heavy use and I push my devices to the limit. The kindle it has held up well and continues to do so to this day so 9 years and counting. The thing about the orginal is you can access the battery where on newer models you can not so they may not last 9 years.
