My laptop battery has died. It's a Lenovo ideapdad 100-151BY. I'm not sure if the laptop will work once the battery life drops to 0% so I'll buy another. Does anyone know the best place to buy one from? I found a new one on ebay for £23 but someone told me it might be dangerous. Someone recommended a site called ibatterys.co.uk. The site says the battery has been tested, so it sounds used. Reviews on trustpilot are mixed so I'm not sure about this site. Can anyone help? Thanks.
