Where This Battery Is Used
- Front-access UPS battery cabinets - shelves of narrow blocks wired from the front, common in modular and lineup-and-match UPS enclosures.
- Telecom and cable headend ride-through - short-duration backup to generator start where the rack is serviced from the aisle.
- Retrofits of narrow front-terminal blocks - the 4.24 inch width matches shelves cut for slim high-rate cases.

Frequently Asked Questions
Why does East Penn give the HR3500ET a year more warranty than the HR3500?
Form 0986 sets the High Rate term by terminal style: 4 years for the front-access ET models and 3 years for top-terminal blocks. The two HR3500 variants share the 370 watt rating and the 10-year design life; the extra year follows the case. If your cabinet accepts either, the ET is the longer-covered choice at 4 lbs more per block.
How many HR3500ET blocks fit on a 24-inch shelf?
Five, if the shelf is a true 24 inches clear and the manufacturer's spacing allows it, since each block is 4.24 inches wide; four with the usual air gap between cases. The 4.97 inch front-access blocks in the Deka range fit four to the same shelf at most. Send the shelf drawing or the cabinet model and a specialist confirms the layout against East Penn's outline drawing.
Why is there no 1-minute rating at 1.75 volts per cell?
East Penn lists it as not available on Form 1552 at the 1.70 and 1.75 VPC rows. A 1-minute discharge at a high end voltage is outside the range the table covers for this block. For 1-minute sizing use the 1.67 VPC row, 957 watts per cell, or the lower end voltages the table does publish. If your UPS specifies 1.75 VPC at one minute, say so and a specialist will check the alternatives rather than guess a number.
Is the HR3500ET a telecom battery or a UPS battery?
It is rated for UPS work, in watts per cell over minutes, and the East Penn form that governs its warranty is the High Rate form. It is used in telecom plant where the requirement is short ride-through to generator start rather than hours of reserve. For an eight-hour reserve string, the amp-hour rated Unigy I blocks such as the 12AVR150ET are the right series; for fifteen minutes at high power from a front-access shelf, this is.
