Compatible Replacement Kit for Upsonic LAN 40

This kit supplies two 6V 4.5A sealed lead-acid batteries built to fit the Upsonic LAN 40 UPS. It is intended for administrators or technicians who need to restore backup runtime on that specific unit. The pack arrives factory fresh and includes step-by-step installation instructions for a straightforward swap.

Two High-Rate Discharge Cells in One Package

The cartridge combines a matched pair of 6V 4.5A cells so the UPS receives balanced voltage from day one. No soldering or custom wiring is required; the batteries slot into the existing compartment using the original connectors. This design reduces downtime during scheduled maintenance windows.

Sealed Lead-Acid Chemistry for Stable Operation

SLA construction keeps the cells maintenance-free and prevents electrolyte leakage in normal rack or tower orientations. Self-discharge remains low during storage, so spares stay ready for future replacements. The chemistry delivers consistent high-rate discharge without active cooling or audible fan noise.

Questions about this item

Does the Upsonic LAN 40 kit use a standard SLA interface that caps at 4.5A per battery?

Yes, each 6V 4.5A battery uses a standard sealed lead-acid design with F2 terminals, so the 4.5A rating is the practical discharge limit.

What physical space and mounting points does the dual-battery kit require inside the UPS?

The kit contains two 6V 4.5A bricks that sit side-by-side in the existing battery tray; no extra brackets or rails are needed.

How do I install the kit, and which step do people most often get wrong?

Disconnect power, open the front cover, unplug the old pack, connect the new red-to-red and black-to-black leads, then close the cover; the common mistake is reversing the polarity on the second battery.
