Some replacement LG mobile phone batteries include the BLI-959-8WI and BLI-1064-9, notes BatteryGiant.com. These units vary from each other because they need to function properly in the type of phone in which they are installed. Part numbers are used to reference the original batteries that were installed from factory.
Replacement phone batteries can be purchased from several types of distributors, including online stores such as BestBuy.com and BatteryGiant.com. As of 2015, BestBuy.com limits its selection to the types of phones available through its store.
BatteryGiant.com offers batteries for all types of products including cellular devices, computers and cameras. The batteries can be directly ordered from its warehouse and shipped to the consumer.
