EnerSys PowerSafe SBS XL series 150Ah front terminal configurations - compatible with standard telecom rectifier systems, energy storage inverters, and -48VDC infrastructure requiring extended runtime capacity

We've Documented Extended Runtime Battery Failure Patterns

• Macro Cell Outage Impact: Single site failure during utility outage affects thousands of subscribers with restoration costs including crew dispatch, generator rental, and customer credits - battery capacity fade represents the primary failure mode
• Energy Storage Investment Risk: Batteries failing before projected service life create substantial increase in levelized cost of storage, undermining renewable integration business cases and return on investment
• Critical Load Runtime Shortfall: Batteries degrading below design capacity cannot support calculated backup windows, forcing premature replacement or emergency load shedding during actual outage events

Battery specialists since 2010 serving extended runtime applications. Because calculated backup windows aren't negotiable.

Q: "Can I use SBSXL-150F-FT batteries in energy storage systems with renewable integration?"
A: Yes. The TPPL chemistry handles partial state-of-charge cycling common in solar and wind applications without sulfation damage. The 150Ah capacity provides substantial energy storage for peak shaving and load leveling. Ensure your charge controller supports the recommended 2.27Vpc float voltage with proper temperature compensation. The 10-20 year service life makes these batteries ideal for renewable installations requiring long-term reliability.

Q: "What discharge rate should I use for capacity testing?"
A: EnerSys specifies 8-hour rate (18.75A) to 1.75Vpc at 77°F for nameplate capacity verification. For faster testing, use 1-hour rate (150A) to 1.67Vpc, expecting approximately 85-90% of rated capacity. Always document actual ambient temperature during testing - results at elevated temperatures require correction factors. Capacity retention above 80% of rated confirms continued service viability.

Q: "How does the 4.9 milliohm internal resistance affect my DC system design?"
A: The exceptionally low internal resistance provides minimal voltage drop during high-current discharge events - critical for maintaining proper equipment operation throughout extended backup windows. In -48VDC systems, the low resistance enables accurate runtime calculations and prevents premature low-voltage disconnects. During float operation, reduced I²R heating contributes to the extended service life in high-temperature environments.
