Where This Battery Is Used
- Central office plants - the -48V reserve where fewer, larger monoblocs simplify the string.
- Aggregation and headend sites - long-duration holdover for the equipment a region depends on.
- Standby plants with long generator starts - sites where the battery bridges more than a transfer switch click.

Frequently Asked Questions
Is TEL12-180F the same battery as TEL12-180Fa?
C&D's current published catalog lists the model as TEL12-180Fa, and the 181 Ah rating class is the same. Manufacturers revise suffix letters between catalog generations, and the label on the delivered unit reflects current production. If your records or your existing string say 180F, send the label photo with your quote request and the specialist confirms the exact build in writing before anything ships.
What does the 4,500 A short-circuit figure mean for my install?
It is a fault characteristic, separate from any usable rating. That number tells your protection engineer what a bolted fault across the terminals can deliver, which sizes the overcurrent protection and the cable. Reserve time still comes from the amp-hour ratings, so size the string from the 8-hour figure and the load, and leave the 4,500 A to the breaker calculation.
What connects to a 1/4-20 terminal?
A bolted cable lug on a threaded copper-alloy insert, which is how C&D terminates its larger TEL monoblocs; the smaller models in the line use M6 hardware instead. Use the washer stack and torque figure from the install drawing for your build, and confirm lug sizing with the quote if you are replacing hardware along with the batteries.
