1. Excellent Safety Performance: As the aluminum bluster outer package is different, in the metal-shelled liquid lithium power cell, no safety problems arise, as it ca n't detonate, only expand.
2. super thin design: suitable to all kinds of super thin electrical appliance, but liquid lithium ion will have technical bottleneck as thickness is less than 3.6mm;
3. Light Weight: The polymer lithium cell is 40% lighter than

the same specification of the steel shell liquid lithium cell, and 20% lighter than aluminium shell liquid lithium cell.
4. High Capability: The polymer capacity is 10-15% more than the same specification steel shell and aluminium shell liquid lithium cell.
5. Low Internal Resistance: At present the impedance of our products can be made below 35m, better using battery capacity. Because of the difference of impedance, the usage time can differ by 20-50% with the same
6. Customized Shape: The thickness and shape can be made according to the requirements of customers. Some special shapes as arc-shape battery can also be made.
7. Excellent Discharge Performance: LIP applies gelled electrolyte with more stable discharge characteristics and higher discharge plateau.

Procurement suggestions

UPS batteries—whether sealed lead-acid (SLA) or lithium—must match the original voltage, capacity (Ah), and physical dimensions precisely. For replacements, choose suppliers providing IEC 60896-21/22 (for SLA) or UN38.3 + MSDS (for Li-ion) certifications. Lithium options offer longer life and lighter weight but require compatible UPS firmware. Ideal for data centers or medical equipment where runtime reliability is critical. Avoid non-branded cells without cycle-life data—reputable vendors include BMS specifications and charge/discharge curves. Always recycle old batteries per local regulations. (for reference only)
