Ni-MH battery for embedded systems
Battery technologies When a new battery technology is introduced on the market, it does not « kill » the other battery technologies. Because it comes with new benefits, but also with some weakness. The best battery technology does not exist. For each particular application, we have to identify the more relevant battery technology. Today, the oldest battery technology (Lead-acid) is the 1st one in term of sales. 2 ARTS Energy Confidential & Proprietary Feb. 2019
