The situation

In Pakistan there is no local test for a battery to fail

PSQCA, Pakistan's standards authority, does not operate a lithium battery testing laboratory. The country imports several gigawatt hours of lithium storage a year, and none of it is required to pass a local safety test before it is sold to a household.

That means the phrase tier one cells, which appears on almost every battery listing in this market, is a claim about sourcing rather than a test result. It is unverifiable by the buyer and carries no obligation on the seller.

We take the opposite approach. Every step from cell selection to commissioning is carried out or verified by one company, and the pack is certified to international standards whose certificates we will hand you on request.

Pakistan has no mandatory safety standard for lithium storage, so the only meaningful assurance is knowing who did each step. Every layer here is carried out or verified by the same company that answers the phone in year four.

The certifications

What each standard actually tests

  • UN38.3

    The transport standard. Covers altitude simulation, thermal cycling, vibration, shock, external short circuit, impact, overcharge and forced discharge. A pack without it should not legally be shipped by air or sea.

  • IEC 62619

    The standard for secondary lithium cells in industrial and stationary applications. Covers internal short circuit, thermal propagation and functional safety of the battery management system.

  • CE

    European conformity marking, covering electromagnetic compatibility and low voltage requirements for the product as placed on the market.

  • LiFePO4 chemistry

    Lithium iron phosphate is more thermally stable than the nickel-based chemistries used in consumer electronics, with a higher thermal runaway threshold. It is the appropriate chemistry for a cabinet inside a home.

How to read a battery quote

The same specification, described two different ways

None of the claims on the left are illegal in Pakistan, and most of them are not even untrue. They are simply unfalsifiable, which is the point. Ask for the version on the right.

What a typical listing says compared with What we put in writing
What to checkWhat a typical listing saysWhat we put in writing
CellsGrade A tier one cells, with no batch, no supplier and no way to check.LiFePO4 cells graded and logged by batch, with the assembly done and recorded by us.
CapacityA single kWh figure, with no statement of whether it is nominal or usable.Nominal energy and depth of discharge published separately, so you can work out the usable figure yourself.
Cycle lifeA bare number, commonly 6,000 or 8,000, with no residual capacity threshold attached.Cycle life stated against 70 percent residual capacity, which is the only way the number means anything.
CertificationCertified mentioned in the copy, with no certificate offered.CE, UN38.3 and IEC 62619, with the certificates available on request before you buy.
CompatibilityWorks with all hybrid inverters.Eight named brands, tested in real installations, with the working settings documented.
WarrantyFive years, honoured by an importer who may or may not be trading in year four.Five years replacement plus three years service, honoured by the company that installed it.

Buyer guidance

What to ask any battery supplier, including us

If a supplier cannot answer these in writing, that is itself the answer. Take this list to whoever else you are considering.

  • Which certifications does the pack hold, and can I see the certificates?
  • What is the cycle life, and at what residual capacity is it measured?
  • What is the depth of discharge, and is the quoted capacity usable or nominal?
  • What is the operating temperature range, and what happens above 45 degrees?
  • Who honours the warranty, and where are they located?
  • What is the fire protection strategy at cell and cabinet level?
  • Which inverters is it tested against, by name rather than by category?
  • Who commissions the system, and what documentation do I keep?

Safety questions people actually ask

Is it safe to mount a lithium battery inside the house?
With LiFePO4 chemistry, a certified pack and a competent installation, yes. Lithium iron phosphate has a substantially higher thermal runaway threshold than the nickel-based chemistries used in phones and laptops, which is why it is the chemistry used for stationary storage. The installation matters as much as the chemistry: correct isolation, correct cable sizing, correct ventilation clearance.
What actually happens if a cell fails?
The battery management system monitors cell voltage, current and temperature and isolates the pack before a fault propagates. On the Citadel there is an additional layer, with perfluorohexanone and aerosol suppression inside the cabinet and physically separated electrical and hydraulic circuits.
How do I verify the certificates are genuine?
Each certificate carries the issuing body and a certificate number that can be checked with that body directly. We would rather you did that than take our word for it.
Does the warranty survive if I move house?
Yes, provided the cabinet is uninstalled and reinstalled by us or by an engineer we have approved. Tell us before it is moved, not after.
Why does LiFePO4 matter rather than just lithium?
Lithium is a category, not a chemistry. Lithium iron phosphate has a markedly higher thermal runaway threshold than the nickel manganese cobalt cells used in phones, laptops and most electric vehicles. For a cabinet mounted on a wall inside a family home, that difference is the whole argument.
Do I need to tell my insurer about the battery?
Check your policy. Most Pakistani household policies say nothing specific about storage, but disclosure costs you nothing and non-disclosure can cost you a claim. The certification documents are what an insurer will ask to see, and we will give you copies.
What clearance does a cabinet need around it?
Enough for ventilation and for service access, which is a design decision rather than a rule of thumb, and it differs between the wall mounted Anchor and the floor standing Beacon. The survey establishes the position before anything is ordered.
What happens at the end of the battery life?
At 70 percent residual capacity the pack still works, it simply holds less. When you do replace it, we take the old cabinet back. Lithium recovery in Pakistan is immature, and the honest position is that we handle disposal responsibly rather than claiming a recycling chain that does not yet exist here.

Where to next

Ask us for the certificates before you ask us for a price

We will send the CE, UN38.3 and IEC 62619 documentation for the cabinet you are considering, with the issuing body and certificate number so you can verify them independently.
