It includes a 1250 mAh 3.7V rechargeable lithium-polymer battery plus electronics opening tools and video instructions to help you restore an older GPS. The main tradeoff is that replacement requires careful disassembly, and some buyers report tool quality and occasional battery issues right after installation.
