Frequently Asked Questions (FAQ)

🔌 What are EnerSys batteries used for?

EnerSys batteries are designed for industrial, utility, telecom, and critical backup applications. They provide reliable energy storage for systems like data centers, power plants, switchgear, telecom towers, and emergency backup systems.

⸻

⚡ How long do EnerSys PowerSafe batteries last?

Depending on the model and usage, EnerSys PowerSafe batteries can last up to 20 years on float service or deliver 2000+ cycles in cycling applications. Models like the PowerSafe ESG flooded cells are engineered for long-duration reliability.

⸻

🔋 What’s the difference between VRLA and flooded EnerSys batteries?  

•  VRLA (Valve Regulated Lead Acid) batteries are sealed, maintenance-free, and designed for indoor or controlled environments.
•  Flooded lead-acid batteries, like the PowerSafe ESG series, require periodic maintenance and are ideal for large-scale backup systems like utilities or telecom switchgear.

⸻

🧊 Can EnerSys batteries handle extreme environments?

Yes. Many EnerSys batteries—including SBS and PowerSafe lines—are built to perform in extreme temperatures, with wide operating ranges from -40°C to 50°C, making them ideal for outdoor cabinets, substations, or remote sites.

⸻

📦 Where can I buy EnerSys PowerSafe ESG batteries online?

You can order EnerSys PowerSafe ESG batteries directly from PowRparts.com (https://powrparts.com/collections/stationary-battery-energy-storage-solutions-battery-backup?pf_t_manufacturer=EnerSys) with fast 2-day shipping, competitive pricing, and access to compatible chargers, racks, spill kits, and accessories.

⸻

🔧 Do I need to maintain EnerSys ESG flooded batteries?

Yes. Unlike sealed VRLA batteries, PowerSafe ESG flooded cells require periodic electrolyte checks, terminal inspections, and equalization charges to maximize lifespan. PowRparts provides battery watering systems to simplify this process.

⸻

✅ Are EnerSys batteries UL or ISO certified?

Most EnerSys industrial batteries are UL-recognized and meet stringent ISO 9001 and ISO 14001 quality and environmental standards. Specific datasheets and certifications are available for each battery model.
