🔹 10+ Years Battery Experience 🔹 Fast & Accurate Identification

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

The sealed SLA chemistry ensures safe indoor use and minimal maintenance, making it a practical long-lasting battery option for UPS systems protecting sensitive electronics.

Designed for durability, these batteries tolerate repeated charge/discharge cycles and resist vibration—features that make them well suited for data centers, telecom racks, server rooms, and emergency backup applications.

Customer support is available via email, chat, or toll-free at (800) 657-1303 for any questions about compatibility or installation.
