The Battery Is Usually Not the Problem
When a telecom battery project encounters delays, most people immediately suspect the battery supplier.
In reality, many telecom energy storage projects begin experiencing problems long before the batteries arrive on site.
Over the past few years, one trend has become increasingly common:
Projects fail not because the batteries are defective, but because the procurement requirements were incomplete from the beginning.
This issue is particularly common in:
- Telecom tower upgrades
- BTS backup projects
- Rural network expansion
- Hybrid solar telecom systems
The result is often:
- Delayed commissioning
- Unexpected redesign
- Additional procurement costs
- Site downtime
- Contractor disputes
Mistake #1: Specifying Capacity Without Specifying Runtime
One of the most common RFQ mistakes looks like this:
Need 48V 200Ah Lithium Battery.
The problem?
A battery capacity alone tells suppliers almost nothing about the project.
For example:
Two telecom sites may both request a 48V 200Ah battery.
Site A:
- Load = 800W
Site B:
- Load = 2.5kW
The actual backup performance will be completely different.
Instead of requesting only battery capacity, buyers should define:
- Site load
- Required backup duration
- Future expansion expectations
This allows suppliers to recommend a solution rather than simply providing a quotation.
Mistake #2: Ignoring Existing Telecom Equipment
Many battery replacement projects assume that lithium batteries can simply replace VRLA batteries.
Sometimes they can.
Sometimes they cannot.
Common compatibility issues include:
- Existing rectifiers
- Charging voltages
- Battery monitoring systems
- DC distribution equipment
A battery upgrade should always start with a review of existing infrastructure.
The most successful telecom projects treat battery replacement as a system upgrade, not just a battery purchase.
Mistake #3: No Communication Requirements in the Tender
Modern telecom batteries often support:
- CAN Bus
- RS485
- Remote monitoring
However, many tender documents still focus only on:
- Voltage
- Capacity
- Dimensions
Without communication requirements, suppliers may provide products that technically meet the specification but create integration challenges later.
Communication requirements should be defined before procurement begins.
Mistake #4: Selecting Only on Price
This mistake occurs in almost every market.
A lower battery price may look attractive during evaluation.
However, procurement teams rarely compare:
- Maintenance costs
- Service support
- Technical assistance
- Warranty response
- Project engineering capability
The cheapest quotation often becomes the most expensive project.
Mistake #5: No Provision for Future Network Expansion
Telecom infrastructure rarely remains unchanged.
Sites often require:
- Additional radios
- More transmission equipment
- New monitoring devices
A battery system designed only for today’s load may become insufficient within a few years.
Modular battery architecture is often a better long-term strategy.
A Real Telecom Procurement Scenario
An African telecom contractor requested quotations from multiple suppliers.
The RFQ specified:
- 48V 200Ah battery
- Lithium technology
- Outdoor installation
Nothing else.
After supplier selection, several issues emerged:
- Outdoor temperature exceeded design assumptions.
- Existing monitoring equipment required RS485.
- Backup requirements had been underestimated.
The project required additional engineering work before installation could proceed.
The lesson was simple:
A more detailed procurement specification at the beginning would have reduced project risk significantly.
What Experienced Telecom Buyers Do Differently
Experienced procurement teams typically focus on:
Project Requirements
Rather than battery specifications alone.
System Compatibility
Rather than standalone product parameters.
Lifecycle Cost
Rather than purchase price.
Technical Support
Rather than catalog data.
Future Expansion
Rather than current load only.
This approach generally produces more reliable project outcomes.
Questions Every Telecom Buyer Should Ask Before Issuing an RFQ
Before requesting quotations, consider:
- What is the actual site load?
- How many hours of backup are required?
- Will the load increase in the future?
- What communication protocols are required?
- Is the battery replacing an existing system?
- What environmental conditions will the battery face?
- Who will support commissioning and after-sales service?
These questions often have a greater impact on project success than the battery model itself.
HIZN Engineering Perspective
In our experience supporting telecom projects across Africa, the Middle East, and Southeast Asia, the most successful projects begin with a discussion about the application rather than the battery.
When buyers share:
- Site information
- Load profiles
- Existing equipment
- Future plans
engineers can recommend solutions that reduce technical risk and improve long-term performance.
Conclusion
Most telecom battery project problems originate during procurement, not manufacturing.
By defining project requirements clearly, evaluating compatibility early, and focusing on long-term performance rather than initial price alone, telecom operators and EPC contractors can significantly improve project reliability and reduce lifecycle costs.
A successful telecom battery project starts long before the batteries arrive on site.
