Lithium UPS — Li+ Series

Lithium UPS for Home: Wall-Mounted Li+ Series

It charges faster than a lead-acid system, lasts far longer and saves floor space. Every unit has a 3-year warranty and free delivery across India.

Why Switch to a Lithium UPS?

Lead-acid batteries need regular topping up, take up floor space and need replacing every few years. A lithium UPS removes all that. The battery is sealed inside the unit, so there is nothing to maintain and nothing to spill.

A Lithium Inverter for Home That Looks Good

Li+ mounts on the wall, so it frees floor space and suits flats, bedrooms and shops where a large battery trolley looks out of place. It is also lighter to handle than a tubular battery system.

Total Cost of Ownership

A lithium UPS costs more upfront, but with 3,500+ cycles you can avoid two or more lead-acid battery replacements. If you already own a UPS and only want to change the battery, see our LiFePO4 lithium batteries. Read more in our online UPS price guide.
