Balance of battery power

Bellingham, Wash.-Power system maker Alpha Technologies has announced the debut of its Battery Balancer product, which both monitors voltage levels of 36V and 48V battery strings and instills proper charging for each individual battery.

Service life is maximized as the Battery Balancer ensures that each battery is neither overcharged nor undercharged, and by limiting capacity degradation due to an unbalanced string.

Alpha improves AlphaCell line

BELLINGHAM, Wash.-Alpha Technologies has made additional improvements to its AlphaCell battery offering, which is designed to provide backup power for critical communications powering applications. The line now incorporates a newly-modified grid geometry which the company says has been shown to extend battery service life up to 35 percent over previous models. Additional battery design changes include an improved separator, colloidal gel and thicker grids.
