TPL121000 12V 100AH Telecom Battery High Output Front Terminal CSB
CSB TPL121000 Battery - 12V 100Ah Front Terminal Telecom
Warranty and Design Life
Built for Float, Not for Cycling
- 800 A maximum discharge current - the cell holds voltage through a hard demand 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.
- Maintenance-free AGM with up to 99% gas recombination and a flame-retardant UL 94 V-0 container.

Where This Battery Is Used
- Central offices and cell sites - the -48V plant string that carries the site until the generator picks up.
- 19-inch telecom racks and cabinets - where front access is the difference between a ten-minute service call and pulling the shelf.
- Cable and broadband plant - node and hub cabinets where a truck roll costs more than the battery.
- Fiber nodes and remote terminals - unmanned sites on a scheduled maintenance visit.
- Small data center and edge deployments - float service where a twelve-year life beats a three-year swap cycle on total cost.

Frequently Asked Questions
What is the difference between the TPL121000FR and the TPL121000TFR?
The case, not the capacity. Both are rated 100Ah at the 8-hour rate. The FR is the 19-inch case sold on this page: 20.16 by 4.44 by 10.11 inches, 84.4 lbs. The TFR is the tall case: 15.35 by 4.13 by 11.02 inches, 76.7 lbs. Nearly five inches shorter front-to-back and about an inch taller. Compare the two on a capacity spec sheet and they look interchangeable; put the wrong one in a fixed rack and it does not fit.
Is it 100Ah or 107Ah?
Both, at different rates. 100Ah at the 8-hour rate to 1.75 VPC is the nameplate and the figure to size against for telecom float service. At the 20-hour rate the same battery gives 107Ah, and at the 8-hour rate to a 1.80 VPC end point it gives 96.8Ah. None of these is wrong; they are three measurements of one battery. Match whichever basis your plant documentation uses.
How is a 12-year design life different from the warranty?
Design life is CSB's engineering estimate of how long the cell can serve under ideal float at 25°C. The warranty is the three-year period CSB will replace a failed unit. The gap between the two is normal across the industry and it is not a catch. Design life is an engineering estimate; the warranty is what CSB will replace.
What torque do the terminals take?
M6 bolts into I2 threaded lead-alloy inserts at 44.9 in-lbs (5.1 Nm), with a tolerance of plus or minus 9 in-lbs. That is much lower than the 110 in-lbs a 1/4-20 top post takes, and over-torquing a lead-alloy insert strips it. Use a torque wrench set to that value.
Does temperature affect the twelve-year life?
Substantially. The 12-year figure is at 25°C (77°F), and the rule of thumb across VRLA chemistry is that life roughly halves for every 8 to 10°C of sustained elevation. A cabinet running at 35°C is not a twelve-year installation. If you know a site runs warm, tell us and we will talk about whether a high-temperature line is the better buy.
How do I confirm this is the right battery before ordering?
Send a photo of the label on the unit you are replacing plus the tray dimensions. Voltage, capacity basis, terminal type and footprint are the four that have to match, and FR against TFR is the one most often missed. We would rather talk you out of the wrong battery than process the return.
Send the quantity, your delivery ZIP and your requested-by date. A specialist confirms availability, the case variant, volume pricing and freight in writing, with no obligation to buy.
