CSB XHRL12475WFR Battery - 12V 478W Per Cell Extreme High Rate AGM

The XHRL12475WFR is rated 478.17 watts per cell at the 15 minute rate to 1.67 volts per cell at 25°C, or 2,869 watts across the block, against a badge that reads 475. The number to read alongside it is 2.30 milliohms of internal resistance, and that figure is the reason this size is worth a second look: it is the lowest in the entire XHRL range, lower than the larger XHRL12620WFR at 2.40. Internal resistance is what governs how far a long string sags in the first seconds of a hard step, so on that one measure the 475 outperforms every other block CSB builds in this line, including the one above it. Coming up from the XHRL12410WFR buys 60.84 more watts per cell for 7.93 more pounds and 1.35 more inches of length, and drops resistance from 2.90. The block runs 79.78 lbs in a group 31 case 13.50 by 6.69 inches standing 8.53 inches tall, on an I2 threaded lead alloy insert that takes an M6 bolt, with 3,449 amps of short circuit current and a 47.50 amp charge ceiling.

Warranty

Warranty. CSB's term on the XHRL Extreme High Rate Long Life range is 4 years. Design life is a separate figure: up to 10 years in standby service at 25°C (77°F), and greater than 12 years on the Eurobat 20°C basis. Country of origin is Taiwan. Terms are confirmed in writing with your quote.

The Lowest Internal Resistance CSB Publishes in This Range

2.30 milliohms internal
Lower than every other XHRL block including the larger 620, which CSB publishes at 2.40, so voltage holds better here than one size up.
478.17 watts per cell at 15 minutes
To 1.67 volts per cell at 25°C, or 2,869 watts across the block, with 880.17 watts per cell at the 5 minute rate.
Group 31 case at 8.53 inches tall
The same 13.50 inch length as the XHRL12620WFR but 2.32 inches shorter, so it suits a tier the taller block cannot enter.
  • 119 Ah at the 20 hour rate - to 1.75 volts per cell at 25°C per the CSB price list; the per-part datasheet rates this series in watts per cell rather than amp hours.
  • 3,449 amps short circuit current - the figure a protective device and its interrupting rating get checked against on a new string.
  • 47.50 amps maximum charge current - 16 percent above the XHRL12410WFR, so recharge time holds as the bank grows.
  • 800 amps over 5 seconds - the published peak, unchanged across the XHRL range and quoted as inrush headroom rather than a sustained rating.
  • Equalization at 14.4 to 15.0 VDC per battery - with the float band running 13.5 to 13.8 VDC, both referenced to 25°C (77°F); a cabinet that runs warm belongs at the low end of the float band.

Where This Battery Is Used

  • Large UPS strings on a group 31 shelf - banks carrying a floor through a transfer, where the first fifteen minutes decide the sizing.
  • Plant with a hard step load profile - installations where voltage sag in the opening seconds matters more than total reserve, which is what the 2.30 milliohm figure speaks to.
  • Tiers that will not take the taller 620 - the same 13.50 inch length in a case 2.32 inches shorter, for shelves with limited vertical clearance.

Ordering and Freight

The XHRL range is a non-stock line, so quantities are confirmed with a lead time rather than shipped from the shelf. Minimum order is four blocks, and at 79.78 lbs each a four block set comes to roughly 319 lbs. Sets ship freight pre-paid by LTL to a commercial address, and a residential or limited-access delivery adds $100, the liftgate and access charge the carrier passes through. Send the block count, your delivery ZIP and the date it has to be on site, and a specialist returns volume pricing, lead time and freight in writing in 24 to 48 hours.

Frequently Asked Questions

Why is this listing sometimes shown as XHRL124575WFR?

A keying error that has followed the part through our catalog and into the page address. CSB's part number is XHRL12475WFR and its datasheet is published under XHRL12475W. The extra 5 is not a variant and there is no such part in CSB's range. Both forms describe this battery, and anything ordered against either one ships as the XHRL12475WFR.

How can the smaller block have lower internal resistance than the 620?

Because resistance is set by plate area, grid design and internal connection rather than by capacity, so it does not track size in a straight line. CSB publishes 2.30 milliohms here and 2.40 on the XHRL12620WFR, and the same inversion appears near the top of the XPL and TPL ranges. On every discharge column the 620 is the larger battery. On this one row the 475 is ahead, so a design that turns on voltage holding rather than total reserve may be better served here than one size up.

What changes moving up from the XHRL12410WFR?

Length goes from 12.15 to 13.50 inches, height from 8.41 to 8.53 and weight from 71.85 to 79.78 lbs. You gain 60.84 watts per cell at the 15 minute rate, 16 more amps of charge ceiling and a drop from 2.90 to 2.30 milliohms. The group size moves from 27 to 31, which is the change most likely to need a shelf check rather than the weight.

What torque goes on the terminals?

44.9 lbf-in, with a tolerance of plus or minus 9.0, which is 5.1 N-m plus or minus 1.0, into an I2 threaded lead alloy insert taking an M6 bolt. Lead alloy inserts strip if they are over-torqued, and the figure is well below what a quarter-inch top post would take, so carrying a setting over from a different battery is the common way this goes wrong. Use a calibrated wrench and record the reading.

Next rating up: CSB XHRL12620WFR620 watts per cell at 15 minutes in the same 13.50 inch length, at 104.03 lbs and 10.85 inches tall.
Sizing on voltage holding rather than reserve?

Send your step load profile, the transfer window and the shelf you are working inside. A specialist puts the candidates side by side on resistance and the 15 minute column, and quotes with lead time in writing.
