Technology

We dissolve sulphation — the real reason batteries die.

Around 85% of lead-acid batteries fail from sulphation, not age. A micro-controlled device sends electronic pulses at a calibrated frequency and amplitude that break those crystals down — restoring capacity, and drawing only milliamps to do it.

The root cause

Sulphation, not age, is what kills them.

As a battery discharges, lead sulphate forms on the plates. A full recharge clears the soft crystals — but incomplete charging lets them harden into the greenish-white scale that coats the plates of most lead-acid batteries, choking capacity and dropping the electrolyte's specific gravity until the cell is written off.

~85%

of lead-acid batteries carry the sulphation that BLESS addresses.

Specific gravity

falls as acid is consumed — the first sign of decline.

Hard scale

insulates the plates, so charge no longer holds.

How the pulse works

Calibrated pulses, tuned to the cell.

A micro-controller emits electronic pulses at a precise frequency and amplitude, perfected in-house. The pulses de-bond the hardened sulphate; the freed crystals dissolve back into the electrolyte and restore its specific gravity. Run continuously, the device never lets more than a miniscule amount of sulphate accumulate — so the battery keeps performing near its rated capacity.

1De-bond. Pulses shatter the bond holding sulphate to the plate.

2Recycle. Freed crystals dissolve back into the electrolyte.

3Restore. Specific gravity recovers; capacity returns.

DISCHARGE — SOFT SULFATION

PbO₂ + Pb + 2H₂SO₄ → 2PbSO₄ + 2H₂O

Sulphuric acid is consumed; specific gravity falls.

PULSE — DESULFATION

2PbSO₄ → PbO₂ + Pb + 2H₂SO₄

Crystals de-bond and dissolve back; specific gravity recovers.

A continuous process — the device draws only milliamps and never lets more than a miniscule amount of sulphate re-form.

Safe by design

Engineered to help every battery — and harm none.

Milliamp draw

Pulls only milliamp-level current — no impact on the battery's warranty conditions.

≥30% residual

Installs on any battery — new or in-use — with at least ~30% of life left.

Every LAB type

Flooded, AGM and gel — across both starting and deep-discharge duty.

−20°C … +55°C

Effective across the full operating range, hot climates included.

Simple install

Red lead to positive, black to negative — no removal from service.

Honest limits

Works on sulphated cells — not on short-circuited, leaked or bulged batteries.

Among the chemistries

Lead-acid endures because nothing beats it on cost.

Newer chemistries keep arriving, yet the lead-acid market keeps growing — it's the cheapest, most recyclable, lowest self-discharge workhorse in the rack. Its one real weakness is sulphation. That's the weakness our technology removes.
