Description  

CSB HRL12540W Battery - 12V 540W High Rate Long Life AGM

The HRL12540W is CSB's high-rate, long-life UPS cell, rated 542 watts per cell at the 15-minute rate to 1.67 volts per cell. CSB rates the HRL series in watts, not amp-hours, because that is how a UPS runtime is sized: the load is a kilowatt figure and the runtime is minutes, not hours. At 2.60 milliohms internal resistance it is one of the lowest-impedance blocks in the CSB range, and it will deliver 800 amps on a hard demand. Top terminal, M6 bolt, 96.76 pounds.

Warranty and Design Life

CSB warrants the HRL mid-to-large range for 4 years. Design life is a separate figure: up to 10 years in standby service at 25°C. Country of origin is Taiwan. Terms are confirmed in writing with your quote.

What "High Rate Long Life" Means Here

838 W/cell at 5 minutes
The short-duration number, at a 1.67 VPC end point. A UPS that only has to bridge to a generator lives in this column, not in the 15-minute one.
2.60 milliohm internal resistance
Lower impedance means less voltage sag in the first seconds of a transfer, and it is the baseline your IEEE 1188 ohmic trending measures drift against.
Pure lead, long-life grid
The HRL series pairs high-rate plate design with pure lead construction. That combination is what separates a ten-year standby life from the five-year one a standard high-rate block gives you.
  • 542 watts per cell at the 15-minute rate to 1.67 VPC is the nameplate figure and the one to size a UPS runtime against. CSB publishes no amp-hour rating for the HRL series.
  • 800 A maximum discharge, 3,523 A short circuit - the cell holds voltage through a hard transfer rather than collapsing into a low-voltage disconnect.
  • UL 1973 listed (MH66728) and UL 1989 recognized (MH14533), built to IEC 60896-21/22:2004, TUV NORD certified to ISO 9001:2015.

Where This Battery Is Used

  • Mid to large UPS plant - the string that carries a data hall or a plant floor through a transfer.
  • Data center and edge deployments - float service where a ten-year design life beats a shorter swap cycle on total cost.
  • Switchgear and control power - documented standby duty on an IEEE maintenance schedule.
  • Medical imaging and lab equipment backup - short, hard demands where voltage sag matters more than reserve hours.
  • Broadcast and process control - loads that cannot ride out even a partial sag on transfer.

Ordering and Freight

Minimum order is 4 units. At 96.76 lbs apiece these ship freight pre-paid by LTL to a commercial address; a residential or limited-access delivery adds $100, which is the liftgate and access charge the carrier bills us. Send the quantity, your delivery ZIP and your requested-by date, and a specialist returns a written quote with volume pricing in 24 to 48 hours. If you need the flame-retardant UL 94 V-0 container rather than the standard 94-HB, say so on the quote request, because that is a build option and not a stock substitution.

Frequently Asked Questions

What is the amp-hour rating of the HRL12540W?

CSB does not publish one. The HRL series is rated in watts per cell: 542 W at the 15-minute rate and 838 W at the 5-minute rate, both to a 1.67 VPC end point. That is the correct basis for UPS sizing, where the load is kilowatts and the runtime is minutes. If your specification is written in amp-hours, send it over and we will work out what fits.

Is the warranty really 4 years?

Yes. A blanket "CSB warranty" figure is not meaningful, because the term runs by series. CSB's terms run by series from 1 year on the GP, UPS and HR ranges up to 8 years on the XHT. The HRL mid-to-large range carries 4 years. Terms are confirmed in writing with your quote.

What is the difference between the HRL series and the HR series?

Design life and warranty, on similar high-rate plate design. The HR series is a five-year design life on a one-year term. The HRL is a ten-year design life on a four-year term, built on pure lead. If the string is going into a site you will not revisit for a decade, the difference is the whole argument. If it is a small UPS that gets swapped on a three-year cycle anyway, the HR is the sensible buy and we will tell you so.

Is the case flame-retardant?

The standard container is polypropylene to UL 94-HB. A flame-retardant UL 94 V-0 container is available on request as a build option. If your installation specification calls for V-0, name it on the quote request rather than assuming, because the two are different parts on CSB's side.

What torque do the terminals take?

M6 bolts into I2 threaded lead-alloy inserts at 44.9 in-lbs (5.10 Nm), plus or minus 9 in-lbs. Over-torquing a lead-alloy insert strips it. Use a torque wrench set for this value.

Does temperature affect the ten-year life?

Substantially. The ten-year figure is at 25°C (77°F), and VRLA life roughly halves for every 8 to 10°C of sustained elevation. A UPS room running warm is not a ten-year installation. Tell us the ambient and we will size the expectation honestly.
