Lithium ion (Li-ion) batteries feature high energy density, high
capacity, light weight and high power.
The voltage of cylindrical type is 9V.Li-ion batteries are one o f
the most popular types of rechargeable battery
for portable electronics, with one of the best energy densities, no
memory effect, and a slow loss of charge when not in use.
