12V 15A Battery Desulfation Charger — Regenerator for Sulphated Batteries

Sometimes — and any seller who promises otherwise isn't being straight with you. Regeneration mode applies controlled desulfation pulses intended to reduce lead-sulphate buildup on plates that are still intact. Where sulphation is the only fault, it may recover usable capacity. It cannot fix an internal short, broken plates, physical damage or dried-out electrolyte. Treat every recovery as an attempt, not a guarantee.

It depends on how far sulphation has progressed. As a rough guide only, mild sulphation may need 4–12 hours and heavy sulphation 24–48 hours; some batteries need two or three cycles and some never respond. Watch the digital ammeter and battery voltage rather than charging to the clock — recovering current acceptance is the sign a cycle is working.

Regeneration mode is for batteries showing sulphation symptoms — short backup, slow charging, resting below 12.4V. Maintenance mode is a float charge for healthy batteries you want to keep ready: seasonal vehicles, DG-set starters and inverter banks between power cuts. A typical routine is one regeneration cycle first, then Maintenance to hold the recovered charge.

Any 12V lead-acid battery between roughly 7Ah and 200Ah — tubular, flat plate, SMF, VRLA, wet cell and AGM — provided you set the current to the figure the battery manufacturer specifies. It is a 12V charger only: not for 24V, 36V or 48V strings, and not for lithium-ion or LiFePO₄. GEL batteries need both mode voltages confirmed with Samco before you connect one.

Sulphation is the hardening of lead-sulphate crystals on a battery's plates. It happens after every discharge, but crystals left too long — by deep discharge, long storage or chronic undercharging — stop dissolving on recharge. They block plate area, cut capacity, and are the most common reason an inverter battery's backup time collapses. A desulfation charger exists specifically to attack this buildup.

On the right battery, yes; on the wrong battery, no. Results are best on batteries whose plates are mechanically sound and whose only fault is sulphate buildup — typically one to five years old, slowly having lost capacity. It does nothing for shorted cells, shed plates or dry batteries, and some sulphated batteries simply never respond. That's why we say: try it, measure the result, keep expectations honest.

For a dealer or anyone with several batteries, usually yes. A failed 150–200Ah tubular battery can cost well over ten thousand rupees to replace, while this charger is a one-time Rs 10,500 plus GST that can attempt recoveries across your whole stock or household for years. For one small car battery near end of life, replacement is often the sensible call.

Yes — those are the classic use cases. 100–200Ah tubular inverter batteries that have lost backup time, solar banks that sat partly discharged through a weak monsoon, and individual 12V units pulled from e-rickshaw strings all fall inside the 7–200Ah range. Never connect it across a full 48V or 60V e-rickshaw string — charge one 12V battery at a time.

Rs 10,500 plus GST, with free shipping to 19,000+ pincodes across India in 3–7 working days. Order on WhatsApp or call 99539 35912; COD and UPI are accepted and a GST invoice is provided. Local buyers can pick up from 21 Gokhale Market, near Kashmere Gate Metro Station, Delhi 110054.

No to both — this model is the exception in the Samco range. Rs 10,500 is quoted plus GST, added at invoice, and no dealer or wholesale discount applies on this model. Every other Samco charger is priced with GST included.

AGM, SMF, VRLA, wet cell, tubular and flat plate types are all supported. GEL batteries specify lower charging voltages than flooded cells, so confirm both the Regeneration and Maintenance mode voltages with Samco before connecting a GEL battery. Lithium-ion and LiFePO₄ packs are not supported at all.

Six months against manufacturing defects. Unopened units in original packaging can be returned within 3 days, with return shipping paid by the customer. Full terms are on the warranty and returns page.
