Batteries
SMF, tubular and lithium-ion battery banks — supplied, sized and maintained as part of the power system, not as an afterthought.

What it is
COMPACT supplies and maintains the battery bank as part of the power system, not as an afterthought. The bank is the single biggest lifecycle and reliability variable in a UPS installation — chemistry, sizing and maintenance regime matter more than a headline Ah number.
Sealed maintenance-free (SMF), lead-acid tubular and lithium-ion options are offered, from quality brands, sized after a pre-sales load study.
What it does
SMF (VRLA)
Sealed maintenance-free valve-regulated lead-acid — the common choice for indoor UPS rooms.
Tubular
Lead-acid tubular batteries, C-10 and C-20 rated, for longer autonomy and deep-cycle duty.
Lithium-ion
Lithium-ion banks where footprint, weight, cycle life or temperature range justify it.
Sized to the load
Runtime band chosen from the pre-sales load study — typically enough for orderly shutdown, or longer where a generator bridges long outages.
The engineering value
Correct sizing beats over-sizing
A bank matched to the real critical load and autonomy target — with a maintenance plan — outlasts an oversized bank that is never load-tested.
Backed by battery services
Health checks and replacement are delivered through COMPACT's battery services team.
Where it fits
Typical applications for this range — not an exhaustive list.
- All COMPACT online UPS installations
- Retrofit and end-of-life battery replacement for existing fleets (any brand)
