Major online retailers such as Amazon.com and AliExpress sell replacement batteries for tablets, allowing the user to change an original battery that is no longer functioning correctly. Electronic repair businesses such as Batteries Plus Bulbs also have replacement batteries and offer in-store repair for tablets and mobile devices.
Auction websites such as eBay also sell replacement tablet batteries. Replacement batteries are often model-specific and may be manufactured by the original manufacturer or a third-party seller. Replacing a battery in a tablet is typically relatively easy and normally requires removing the back panel and unhooking the connector. Guides available on sites such as Tom's Guide explain the replacement process.
