DEKA Unigy UPS 45HR2000 High Rate Series Battery
DEKA Unigy UPS 45HR2000 High Rate Series Battery
Deka Unigy 45HR2000 Battery - 12V 168 WPC High Rate UPS AGM
Warranty
Small Case, Full Design Life
- Sealed AGM VRLA - glass mat separators that resist puncture, a heat-sealed case and cover, epoxy-sealed posts, and self-sealing flame-arresting valves, all 100 percent tested at the factory.
- UL 1973 certification - for energy storage applications, alongside UL recognition requirements and IEEE recommended practices.
- Reinforced case - flame-retardant polypropylene, UL 94 V-0, limiting oxygen index above 28 percent, built to resist bulging under high-rate discharge.
- Float window published - 13.50V per battery plus or minus 0.5 percent at 77°F, range 13.42V to 13.57V.
- Constant-power table to 1.60 VPC - East Penn publishes six end voltages from 1.60 to 1.75, so a UPS specified to an unusual end voltage can still be sized from the manufacturer's own data.

Where This Battery Is Used
- Mid-sized UPS strings - tower and rack UPS units in the 3 to 10 kVA class whose battery bays take a block under 9 inches long.
- Switchgear and breaker control - trip and close power on a maintained float, where the 1-minute rate of 526 watts per cell matters more than runtime.
- Telecom and cable plant ride-through - short-duration backup to generator start at small hubs.

Frequently Asked Questions
What does the 45 in 45HR2000 refer to?
East Penn's flyer does not explain it. Several High Rate part numbers carry a prefix, U1HR1500 and 31HR5000 among them, and the prefix changes with the case while the HR figure tracks the rating. Treat the 45 as part of the model name and match the block to your tray on the published dimensions, 8.99 by 5.47 by 8.27 inches, rather than on the prefix.
How does the 45HR2000 compare with the U1HR1500 for a small UPS?
It gives roughly 40 percent more power at every discharge time, 168 against 119 watts per cell at 15 minutes, and it carries a 10-year design life against 5, with a 3-year East Penn term against 1. It is 1.27 inches longer, 0.26 inches wider and 1.59 inches taller, and 14 lbs heavier. Where the tray takes the larger block, the 45HR2000 is the longer-lived choice; where it does not, the U1HR1500 is the one that fits.
Can I size a 45HR2000 string to a 1.60 VPC end voltage?
Yes. East Penn's Form 2046 table runs from 1.60 to 1.75 volts per cell in six steps. At 1.60 VPC the 15-minute rating rises to 172 watts per cell and the 1-minute rating to 569. Some UPS manufacturers specify a low end voltage for short-runtime strings; read the row that matches your UPS specification rather than the 1.67 headline figure, and send us the UPS model so a specialist confirms it.
Is the 45HR2000 available with front terminals?
The 45HR2000 is a top-terminal block. East Penn's front-access High Rate models, designated ET, start at larger ratings: the HR3500ET at 370 watts per cell is the smallest front-access block in the range we list. If front access is a requirement at this size, tell us the cabinet and rating and a specialist will say plainly whether the range has an answer.
