Millions of VRLA batteries deployed in telecom cabinets present great challenge for maintenance and replacement. Thermal runaway and early failure are two main concerns which have to be addressed by effective monitoring. Battery warranty claim is often difficult due to lack of data. On 2014 OSP conference in Baltimore Maryland, BatteryDAQ presented a cost-effective solution with a series of compact battery monitors with internal resistance (conductance) and thermal runaway detection. Using any smart phone to scan a QR code on the monitor/cabinet door will instantly gain access to real-time data and history trend. Thousands sites can be managed by a technician with a platform software. Read more details: http://www.batterydaq.com

1. OSP Battery Problems
• Thermal Runaway
• Early Failure
• Maintenance Headaches
• Service Life – Promised vs. Actual
• Warranty Hassles
• Replacement Decisions
• Too many sites
Effective. Validated.

2. When It Comes To Battery Monitoring…
• …“Business as Usual” is no longer “Good Business”
• Thermal runaway
• Batteries died a long time ago
• Good batteries replaced too early
• Low quality batteries
• Charger/rectifier problems
• HVAC conditioner problems
• Batteries did not work when
needed

3. Battery Service Life Contributors

• Materials
• Manufacturing
• Transportation and Storage
• Environment
• Float Charge
• Cycling Frequency/Depth
•Maintenance
Action Result
Do Nothing Failure when needed, short service life,
thermal runaway, large unexpected costs
Wrong BMS Worse than doing nothing, many false
alarms, delayed alarms
Correct BMS Knowledge-based maintenance,
extended service life & decreased expenses,
optimum confidence & increased control

4. Thermal Runaway
• Dangerous
• Costly
• Occurs to any VRLA battery brand
• Proper detection is available
• Avoidance can be achieved
Monitor & take action

5. Warranty Hassles
• What information is
required?
• Do you have the
supporting data?
• Is your only leverage the
amount of business you
give to the vendor? • Proactive maintenance

• Statistical comparison for all
batteries & brands

6. Replacement Decisions
• Confident budgeting
• Detailed, formatted reporting
• Easy to ID troubled batteries
• Extended life means costs savings
Rank all your sites

7. Simple to Install
Comprehensive Data
