Looking for some extra juice for your Nexus One, but won’t allow anything non-Google-sanctioned near your precious smartphone?  Google have added spare batteries for the Android 2.1 smartphone to their online store, with each 1,400 mAh pack priced at $25.

They’re identical to the standard battery that comes with the phone, and are rated for up to 10hrs 2G talktime or 7hrs 3G talktime.  Right now they’re limited to a maximum of five units per order, and it’s worth remembering that they ship from the US so international deliveries might be expensive.
