Battery rejuvenation technology.
Restore lead-acid batteries at end of life — recover lost capacity, extend serviceable life by at least a year, and maximise the return on every battery already in service.
Most batteries are thrown away with 40% of their life unused.
A typical lead-acid battery is designed for around 1,500 charging cycles. In practice it is usually discarded after about 900. That gap is capacity the owner paid for and never used.

Life added per cycle, repeatable
The battery is not worn out at 900 cycles. It is sulphated. Hardened lead sulphate crystals accumulate on the plates whenever a battery sits partially discharged — which is most of the time in inverter, UPS and solar duty. Those crystals block the active material, capacity drops, backup time shortens, and the battery gets replaced. Reverse the sulphation and the remaining design life becomes available again.
Four steps, diagnostic first.
Not every battery is worth treating, so the diagnostic comes before any commitment.
-
Step 1
Diagnose
Capacity, voltage under load and internal resistance are measured to establish state of health and confirm the battery is a viable candidate.
-
Step 2
Desulphate
High-frequency pulses break down the crystalline lead sulphate bonded to the plates, returning active material to the electrolyte.
-
Step 3
Recondition
Controlled boost charging rebalances the cells, supported where appropriate by the Elixir additive.
-
Step 4
Verify
A post-treatment capacity test confirms recovered performance. Batteries that fail verification are recycled, never resold.
The process is sealed. Nothing is opened, and no chemicals are discharged into the environment — which matters both for worker safety and because informal battery handling is a documented source of lead contamination across our markets.
Four outcomes, one process.
Extended battery life
Rejuvenation restores performance and delays replacement. A battery designed for 1,500 charging cycles is often discarded after 900 — the process is repeatable annually until the full design life is realised.
Recovery of lost capacity
Addresses the root causes of failure: sulphation of the plates and elevated internal resistance. Backup time returns to dependable levels rather than degrading further.
Cost savings
Operating costs fall through deferred battery purchases and reduced energy consumption across the fleet. The saving compounds because the cycle repeats.
Environmental benefit
Every battery kept in service is one not manufactured and one not disposed of. No chemicals are opened or released during the process.
Which batteries can be rejuvenated?
| Battery type | Typical application | Suitable |
|---|---|---|
| Flooded & tubular | Inverters, solar storage, home UPS | Yes |
| VRLA & AGM | Telecom towers, data centre UPS | Yes |
| Gel | Deep-cycle and standby storage | Yes |
| Traction | Forklifts, material handling | Yes |
| Physically damaged | Cracked case, buckled plates, internal short | No — recycled instead |

ReStore — frequently asked questions.
What is ReStore battery rejuvenation?
ReStore is a rejuvenation process that recovers lost capacity in lead-acid batteries at the end of their apparent service life. It addresses the two root causes of premature failure — sulphation of the plates and elevated internal resistance — rather than replacing the battery. Each cycle extends serviceable life by at least one year and can be repeated until the battery's full design life is realised.
How many cycles does a lead-acid battery actually deliver?
A typical lead-acid battery is designed for around 1,500 charging cycles, but is often discarded after roughly 900. That gap of about 600 cycles represents capacity the owner paid for and never used. Rejuvenation is what recovers it.
Which batteries can ReStore rejuvenate?
All lead-acid chemistries: VRLA, AGM, gel, flooded, tubular and traction batteries used in inverters, UPS systems, solar storage, telecom towers, forklifts and vehicles. Batteries with physical damage such as a cracked case, buckled plates or an internal short cannot be recovered and are routed to licensed recycling.
How much life does one rejuvenation cycle add?
At least one year of serviceable life per cycle, and the process is repeatable annually until the battery reaches its full design life. Actual recovery depends on the battery's age, chemistry and degree of sulphation, which is why a diagnostic precedes any treatment.
Is battery rejuvenation safe for the battery?
Yes. The process does not open the battery or discharge chemicals into the environment. It works electrochemically, dissolving the hardened lead sulphate crystals that block the plates and restoring active surface area. Every unit is capacity-tested after treatment, and anything failing verification is recycled rather than resold.
How much does rejuvenation cost compared to replacement?
Rejuvenation costs a fraction of a new battery, and the saving compounds because the process is repeatable. The larger financial effect for fleet operators is deferred capital expenditure: replacement budgets move out by years rather than being spent annually.

A diagnostic measures capacity and internal resistance before any work is committed, so you know the likely outcome in advance.
