Why You Need a Battery with True 43Wh Capacity
Dell Chromebook 11 3120 (P22T) is a popular choice for schools, students, and light business use. But the original battery wears out after a couple of years shorter runtime, sudden shutdowns, or the dreaded low battery warning at 40%.
When you search for a replacement, youll see many 43Wh batteries for under $30. Most of them are fake they use recycled or lowgrade cells, slap on a 43Wh sticker, and sell you a 30Wh battery. You end up with half the runtime and a swollen battery in six months.
This 5R9DD battery is different. We deliver true 43Wh capacity using brand new Grade A Liion cells. What you see is what you get.
