CSB XTV12120F2FR-WT Battery - 12V 12Ah Wind Turbine AGM, F2

The XTV12120F2FR-WT is the 12 amp hour wind turbine block from CSB, and it is the part most pitch system packs are built around when 7.2 Ah does not carry the feathering cycle. It keeps the 5.94 inch length of the smaller WT block and grows in width and height to a 3.86 by 4.01 inch case, still on a 0.250 inch F2 tab, at 9.02 lbs. The figures that size a pack are 12.0 Ah at the 20 hour rate to 1.75 volts per cell, 267 watts per battery over 15 minutes to 1.67 volts per cell, and a 180 amp maximum discharge. It charges and discharges from -20°C to 50°C. CSB builds the WT range for what a hub does to a battery, which is cycle it on every pitch event and vibrate it in between, and lists this part as a stock item with a flame retardant case as standard.

Warranty

Warranty. CSB gives 3 years on the XTV-WT range, built in Vietnam. Design life is stated on a different basis and is not the warranty: up to 12 years in standby service at 25°C (77°F). Terms are confirmed in writing with your quote.

The Pack Builder's Block

12.0 Ah in a 5.94 inch length
Same length as the 7.2 Ah WT block, so the two share a tray dimension and differ in width and height.
267 watts at 15 minutes
Per battery to 1.67 volts per cell, against 148 for the 7.2 Ah block, for a pitch drive that has to move a heavier blade.
Stock at CSB
Listed with broken pack pricing, one of two WT parts that are, so a single replacement does not wait on a build slot.
  • 12.0 Ah at the 20 hour rate - to 1.75 volts per cell at 25°C, with 11.3 Ah at the 8 hour rate to 1.75 and 11.1 Ah to 1.80. The standard XTV12120 sheet gives 11.5 Ah at the 20 hour rate, so the WT sheet is the one to size from.
  • 267 watts per battery at 15 minutes - to 1.67 volts per cell, and 260 watts to 1.75, from the WT series tables.
  • 180 amps maximum discharge - with 438 amps of short circuit current and an internal resistance of approximately 15.0 milliohms.
  • 3.60 amps maximum charge current - a higher recharge ceiling than the 7.2 Ah block's 2.16, which shortens the recovery between pitch events.
  • Less than 10 percent self-discharge over 90 days - storable for 6 months at 25°C before a full recharge is required.

Where This Battery Is Used

  • Pitch system battery packs - the series strings in the hub that feather the blades when the converter or the grid drops, on turbines whose blade mass calls for the 12 Ah block rather than the 7.2.
  • Turbine controller and safety chain backup - equipment in the nacelle that has to ride through the same event and the same vibration.
  • Repowering and pack rebuilds - replacing an aged set of 12 Ah F2 blocks on a like-for-like basis, where the dimensions above decide whether the existing tray is kept.

Ordering and Freight

CSB packs this part 6 to a master carton at 55 lbs and lists it as stock with broken pack pricing, so a hub set of eight or twelve ships as two cartons by parcel carrier and a fleet order moves LTL. A residential or limited-access delivery adds $100 for the liftgate and access charge the carrier passes through, and a wind site counts as limited access. Send the quantity, the ZIP and the turbine model, and a specialist comes back with pricing, lead time and freight in writing in 24 to 48 hours.

Frequently Asked Questions

Why does the WT sheet say 12.0 Ah when the standard XTV12120 sheet says 11.5?

Two different sheets, two different measured figures for the same nominal 12 Ah part number. The current WT datasheet (revision RA240618) gives 12.0 Ah at the 20 hour rate to 1.75 volts per cell; the standard XTV12120 sheet (PM260421) gives 11.5 at the same rate. Both agree at the 8 hour rate, 11.3 Ah. If you are sizing a pitch pack, use the WT sheet, because it is the sheet for the part you are buying. If you are comparing the two parts for a stationary cabinet, treat them as the same 8 hour capacity.

How many of these go in a hub?

The turbine decides that. A pitch system runs one string per blade, and the string voltage and the amp hours per string are set by the pitch drive manufacturer, so a three blade turbine might carry anywhere from a handful to a few dozen 12 volt blocks. Bring the turbine model or the original pack part number and a specialist matches the count. What this page can tell you is that each block is 12.0 Ah, 9.02 lbs and 5.94 by 3.86 by 4.01 inches, so you can check the tray before anything is ordered.

Is this an AGM battery or a gel battery?

AGM. The current CSB sheet describes absorbent glass mat construction with pure lead, and the float window of 13.5 to 13.8 volts per battery is the AGM window. CSB's older XTV literature used the phrase "hybrid gel"; the current WT sheet does not, and a gel charge profile would undercharge this block. Set the pitch system charger for AGM.

What happens if a turbine is de-energized for the winter with the pack installed?

The pack stops receiving float charge and begins to self-discharge, less than 10 percent in 90 days at 25°C and faster if the hub is warm. The WT sheet rates storage from -15°C to 40°C, so a cold winter hub is inside the storage window at the bottom, but the battery still needs a full recharge before it is asked to feather a blade again, and within 6 months of its last charge. Plan a recharge into the recommissioning checklist rather than trusting a pack that has sat.

The smaller WT block: CSB XTV1272F2FR-WT7.2 Ah and 148 watts per battery at 15 minutes on the same 5.94 inch length and F2 tab, in a 2.55 inch wide case.
Rebuilding a pitch pack?

Send the turbine model, the count per hub and a photo of the existing block's label. A specialist confirms the part, the tray fit and the lead time, and quotes the whole set in writing.
