Hohm BASE is a marvel at the direction it’s taking. It’s the world’s first oscillating charger developed specifically for li-ion cells in cylinder format. It’s primary purpose: put the “giddy up” back in batteries. Some may refer to this as battery Viagra®. It pushes batteries to their peak ability in both amperage and capacity. Works best on older and/or heavily used batteries. Hohm Base emphasizes on precision, efficiency, consistency, and safety. It is a quad-channel independent lithium-ion battery charger with universal algorithm to charge multiple battery chemistry platforms. It has an advanced STN display to make viewing from any angle possible. This series of Hohm BASE is equipped with a 4 button layout that make operation and option selection intuitive. We are Hohm Tech, and being the best isn’t good enough…so we make things even better.
