Valence Technology batteriesA global technology developer of medical robotic-assisted surgery devices requested a reliable energy storage system to move their critical equipment from room to room. They were concerned that the lead acid batteries within their surgery devices were heavy and needed to be replaced too often. Additionally, the equipment was subjected to significant down time because of the long charge time required of lead acid.

Now that they use Valence’s light weight Lithium Phosphate batteries, the robotic equipment can be moved easily and safely. Each medical system utilizes 3 standard 12 volt UCharge RT series modules. The runtime of the equipment essentially doubled that of the previous battery solution, with faster recharging, and up to 10 times the cycle life.
