CSB XTV121000 12V 100AH AGM Battery for Extreme Temperature Applications
CSB XTV121000 12V 100AH AGM Battery for Extreme Temperature Applications
CSB XTV121000 Battery - 12V 100Ah Extreme Temperature AGM, Group 27
Warranty
The 100 Ah Block, Read Carefully
- 800 amps maximum discharge for 5 seconds - the same ceiling as the 80 Ah and 110 Ah blocks, set by the I2 terminal rather than the plate group.
- 30 amps maximum charge current - a recharge ceiling a cabinet rectifier will rarely approach, so recovery time follows the charger.
- Approximately 4.10 milliohms internal resistance - between the 12800 at 4.70 and the 121100 at 3.60, as the plate count grows.
- 308.7 millimeter case length - about 12.15 inches; CSB's 2026 datasheet misprints the inch figure for this dimension, so the metric one is the number to draw from.
- Non-stock, quoted lead time - CSB builds this part to order in Taiwan and the factory's date is what goes on the quote.

Where This Battery Is Used
- Outdoor telecom and broadband hubs - 48 volt strings of four in unconditioned cabinets, where the hold time has to survive the coldest night on record.
- Remote renewable and hybrid power stations - float service with real discharge events, where the 12 year design life and the temperature rating both matter.
- Roadside, rail and pipeline control houses - equipment that is inspected on a schedule and has to work between inspections.

Frequently Asked Questions
Is the 12 year design life a promise?
It is a ceiling with two conditions attached, and both are on the datasheet. CSB rates this block for up to 12 years in standby service at 25°C, and greater than 12 years on the Eurobat basis at 20°C. Lead acid life falls by roughly half for every 10°C above the reference, so a cabinet that averages 35°C over the summer is running a six year battery, whatever the badge says. The extreme temperature rating means the block will deliver at -20°C and at 50°C; it does not mean it lasts 12 years at 50°C. Plan the replacement interval from the cabinet's actual average, not from the datasheet's reference.
Why does the page give the length in millimeters first?
Because CSB's 2026 datasheet prints the wrong inch figure for it. The metric length is 308.7 mm, which converts to about 12.15 inches, but the sheet's inch column for that row repeats the height figure instead. The millimeter dimension is the one CSB measured and the one to draw from; the inch figure on this page is our conversion of it, and the width and height inch figures are printed correctly on the sheet.
Does the 800 amp limit mean this is a high rate battery?
No. The XTV range is rated for float service outdoors, and 800 amps is a five second ceiling for inrush and fault checking rather than a working figure. CSB's high rate ranges, HR and HRL, are badged in watts per cell at 15 minutes and are the ones built for a short, hard UPS discharge. This block's strength is the opposite end of the curve: 67.2 amps for an hour and 17.5 amps for five, delivered at temperatures the high rate blocks are not rated for.
XTV121000 or XTV121100 for a 48 volt string?
The 121100 carries 10 percent more capacity, 110 Ah against 100, in a case 1.35 inches longer and about 9 lbs heavier, on the same terminal and the same 800 amp ceiling. If the tray is a group 27 and the hold time calculates with margin on 100 Ah, this is the exact fit. If the calculation is tight and the tray accepts a group 31, the 121100 buys the margin without changing the terminal hardware or the protection study by much; its short circuit figure is 2,648 amps against 2,258 here.
Tell a specialist the cabinet's average summer temperature and the hold the site has to carry. The design life on this page is quoted at 25°C for a reason, and the interval the site should budget for follows from the real number.
