What Are the Key Dimensions of Telecom Batteries for Extended Backup Power?
Telecom batteries must balance capacity, size, weight, and safety to provide reliable backup power during extended outages. Dimensions like voltage, amp-hour rating, form factor, and parallel scalability determine system design. RackBattery’s rack-mounted LiFePO4 solutions optimize all dimensions, ensuring telecom sites stay powered efficiently and sustainably.
What Voltage and Capacity Are Required for Extended Backup?
Telecom systems typically use 48–51.2 V setups. To sustain backup for hours, boosting capacity is crucial. A 51.2 V 100 Ah battery holds about 5.12 kWh. Extended use may require multiple units in parallel:
-
2 units → 10.24 kWh
-
4 units → 20.48 kWh
RackBattery units are modular and scalable, enabling easy configuration based on runtime requirements.
How Does Physical Size Impact Installation?
Key size considerations:
-
Rack height (U-size): Most telecom racks use 1U or 2U battery modules.
-
Depth and width: Designed to fit standard 19″ telecom racks.
-
Weight: Each 100 Ah module weighs ~12–15 kg—safe for rack support.
For example:
| Specification | Value |
|---|---|
| Form Factor | 2U, 19″ rack |
| Depth | ~350 mm |
| Weight per 100 Ah | ~13 kg |
Compact dimensions from RackBattery reduce space needs and simplify deployments.

Why Is Weight Distribution Essential in Telecom Racks?
Uneven weight may damage racks or compromise cooling. RackBattery LiFePO4 modules are balanced and fit 19″ racks, ensuring even load distribution. Their lighter weight compared to lead‑acid also reduces structural stress.
How Do Cycle Life and Depth of Discharge Affect Dimensions?
Advanced LiFePO4 batteries support 4,000–6,000 cycles at 90 % depth of discharge. This high efficiency lets you use smaller modules while maintaining long runtimes. RackBattery’s smart BMS ensures safe discharge and maximum lifecycle.
Where Should Telecom Batteries Be Placed?
Telecom backup systems typically integrate into:
-
Rack enclosures: near servers and core equipment
-
Outdoor telecom cabinets: weather-protected
-
Micro data centers/edge locations: compact form factors
RackBattery’s 2U rack modules fit all these use cases with efficient space utilization.
Can Batteries Scale for Larger Data Centers?
Yes. Telecom operators scale using multiple modules. For instance:
-
Standard setup: 2 × 51.2 V 100 Ah for 10 kWh
-
Large-scale: 8–12 modules for 40–60 kWh
RackBattery’s modular design supports safe parallel operation with synchronized BMS.
Which Safety and Cooling Dimensions Matter?
Essential safety features include:
-
Thermal cutoffs
-
IP-rated housings for outdoor use
-
Vent spacing for airflow
-
Integrated cooling channels in design
RackBattery ensures dimensioned vents and certified housings within telecom cabinets.

FAQs
1. What rack size is best for telecom batteries?
2U, 19″ rack modules are industry standard, balancing capacity and space.
2. How many modules are needed for 24-hour backup?
Depends on power draw. A typical 500W telecom load needs ~20kWh, so four 100Ah modules.
3. Can telecom batteries be mounted vertically?
Yes—if manufacturer guidelines for airflow and safety are followed.
4. How does weight impact battery installation?
Lighter LiFePO4 modules reduce strain on racks and ease installation compared to lead‑acid.
5. Are outdoor battery cabinets different dimension-wise?
They include weatherproofing and ventilation, and RackBattery modules fit standard telecom cabinets.
