Siemens EBA-540



The EBA-540, also known as V30145-K1310-X260, is a battery manufactured for Siemens phones. It was only used on the Siemens SX1. The shorter model number isn't written anywhere on the battery, but it's mentioned on the SX1's user manual.

Unfortunately, this battery, along with its compatible replacements are now hard to find and come by, especially on eBay.
