Energy uses include portable devices, transportation vehicles, and stationary power stations, such as those used for the telecommunications industry. Fuel cells are more effective than batteries for backup power because they last longer and are more predictable.

What type of power does a battery provide?

As the most-common source of backup power, batteries provide direct current (DC) power. Lead-acid batteries continually charge with grid power and provide the stored electricity as backup power until the grid is restored. Batteries can supply only as much power as they have stored, and severe weather conditions can hinder their operation.
