EnerSys Genesis EP Batteries

About the EnerSys Genesis EP Battery Line

EnerSys introduced the Genesis EP series to meet the demanding power requirements of professional applications where reliability isn't optional. The TPPL design at the heart of each battery delivers higher energy density than conventional lead acid batteries, meaning more power in a smaller, lighter package. That efficiency has made the Genesis EP a go-to choice across industries for decades.

Every battery in the EP line is a Valve Regulated Lead Acid (VRLA) Absorbent Glass Mat (AGM) design. In plain terms, that means the electrolyte is fully absorbed into the separator material — no free liquid, no spillage risk, and no need for a dedicated battery room. Genesis EP batteries can be installed in virtually any orientation except fully inverted, which gives installers real flexibility in tight spaces and unconventional mounting situations.

A Battery for Every Application

The Genesis EP series is trusted across a wide range of professional settings, including:

• UPS (Uninterruptible Power Supply) systems
• Medical equipment and hospital environments
• Telecommunications and network infrastructure
• Renewable energy storage
• Computer backup systems
• Industrial electronics

The batteries' rugged, flame-retardant housings (UL94 V-0 rated) make them well suited for physically demanding environments with high heat or vibration. At the same time, their sealed, non-gassing design makes them safe to use in occupied spaces like offices and hospitals.

Genesis EP Lineup: Capacities and Dimensions

All five Genesis EP batteries share the same 12-volt platform and M6 female bolt terminals. Here's a quick comparison to help you find the right fit:

• G13EP — 13Ah | 6.89 x 3.27 x 5.08 in | 10.8 lbs
• G16EP — 16Ah | 7.13 x 2.99 x 6.57 in | 13.4 lbs
• G26EP — 28Ah | 6.54 x 6.89 x 4.92 in | 22.3 lbs
• G42EP — 42Ah | 7.72 x 6.50 x 6.69 in | 32.8 lbs
• G70EP — 72Ah | 13.02 x 6.62 x 6.93 in | 53.5 lbs

Key Features Across the Entire Genesis EP Line

• TPPL Technology: Thin Plate Pure Lead construction delivers outstanding energy density and consistent voltage output throughout the discharge cycle.
• Maintenance-Free: Sealed AGM design requires no water additions or routine servicing over the life of the battery.
• Long Cycle Life: Rated for up to 400 cycles at 80% depth of discharge, making the EP series a strong choice for cyclic applications.
• Wide Temperature Range: Operates from -40°F to 176°F (-40°C to 80°C with optional metal jacket), handling extreme environments without skipping a beat.
• Up to 24-Month Shelf Life: Retains its charge for up to two years in storage at 68°F (20°C), ideal for inventory stocking and staged project deployments.
• Safe for Transport: Classified as non-hazardous cargo and approved for land, sea, and air shipment under ADR/RID, IMDG, and IATA regulations.
• UL Recognized: Each battery carries UL recognition (File No. MH12544), and the line is manufactured under ISO 9001 and ISO 14001 certified processes.

Frequently Asked Questions

What does TPPL mean, and why does it matter?

TPPL stands for Thin Plate Pure Lead. Unlike standard lead acid batteries that use a lead alloy, Genesis EP batteries use plates made from highly pure lead. The thinner plates increase the total surface area inside the battery, which improves both energy density and charge acceptance. The result is a battery that's more powerful for its size, charges faster, and lasts longer in cyclic use.

Which Genesis EP battery should I choose?

The best starting point is matching the battery's amp-hour (Ah) capacity to what your equipment requires. Smaller devices like alarm systems or portable electronics typically work well with the G13EP or G16EP. Mid-sized UPS units or telecom equipment often call for the G26EP or G42EP. For larger UPS systems or high-demand installations, the G70EP's 72Ah capacity makes it the top choice in the lineup. When in doubt, refer to your equipment's manual or contact us — we're happy to help.

Are Genesis EP batteries safe to use indoors?

Yes. The sealed, non-gassing VRLA AGM design makes Genesis EP batteries safe for use in occupied environments like offices, server rooms, and hospitals. No ventilation requirements or dedicated battery room is needed.

Can Genesis EP batteries be mounted on their side?

Yes, with one exception. Genesis EP batteries can be installed in any orientation except fully inverted (upside down). This flexibility makes them easy to fit into cabinets, enclosures, and other spaces where upright mounting isn't always practical.

How long do Genesis EP batteries last in storage?

Genesis EP batteries have a shelf life of up to 24 months when stored at 68°F (20°C). This extended storage life makes them a practical choice for keeping spare inventory on hand or pre-staging batteries ahead of a project deployment.

Are Genesis EP batteries approved for air freight?

Yes. The entire Genesis EP line is classified as non-spillable and approved for non-hazardous transport by land, sea, and air, in accordance with ADR/RID, IMDG, and IATA requirements. This simplifies shipping logistics for both domestic and international orders.
