The distinctive all-black Genesis® EP battery was designed in the early 1990s to be a battery that combined several features in one box that previously required separate batteries. It was a breakthrough in VRLA battery technology, analogous to an athlete possessing the qualities of an excellent sprinter and a marathon runner in the same body. The Genesis® EP battery combines several high-performance features including:

• Superior high rate capability
• High energy and power densities
• Quick charge capability
• Long storage life on open circuit
• Deep cycle capability (up to 400 cycles to 80% depth of discharge)
• Ability to recover from repeated deep discharges
• Extreme high temperature (up to 176ºF/80ºC) operability

These features allowed the Genesis® EP battery to make inroads into several non-consumer markets, such as outdoor telecommunications backup, medical devices and high-reliability uninterruptible power systems (UPS), that demand extreme performance from rechargeable batteries.
