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.

Choose this replacement UPS battery to restore or improve the runtime of your PS1100 UPS. As a high-performance UPS battery option, it is built to provide steady output under varying load conditions and to resist the degradation that can shorten battery life. The 12 Ah capacity balances compact size with substantial energy storage, making it a practical, long-lasting battery solution for daily critical-power needs.

Durability is a central focus of this SigmasTek unit. The robust construction and secure F2 terminal connections reduce the risk of poor contacts and premature failure, which helps extend service life in both routine and demanding conditions.
