Quick answer
A 12V battery charger restores charge to 12-volt lead-acid batteries — bike, scooter, car, tractor, inverter, tubular and solar. Match the charger's amps to roughly 10% of the battery's Ah (a 60Ah car battery → 6A; a 150Ah inverter battery → 15A), and pick automatic cut-off at 14.6V so it can never overcharge.

Two 12V batteries in parallel stay at 12V and double the capacity — any charger here can charge that bank at the maker's specified current. Two 12V batteries in series become a 24V bank. No charger on this page can charge it: you'd need the 24V range or the dual-voltage 12V/24V models that auto-detect the bank.
Positives joined, negatives joined. Voltage stays 12V; capacity adds up. A 12V charger handles it.
Negative of the first to positive of the second. Voltage doubles to 24V. A 12V charger cannot charge it.
Read across the bank terminals before connecting. Near 12V → parallel or single. Near 24V → series pair.
Bank reads 24V? You need a different charger — see the 24 volt battery charger range or the dual-voltage 12V/24V models.

Buying guide · India
Straight answers, no jargon — the same advice we give dealers on the phone.
Use the 10% rule: charger amps ≈ battery Ah ÷ 10. A 40Ah bike battery is happy on 3–4A, a 60Ah car battery on 6A, a 150Ah tubular inverter battery on 15A. Higher amps charge faster; lower amps are gentler. Every Samco card and the comparison table above lists the exact Ah range each model covers.
Automatic chargers (3A, 6A) decide everything: they taper current and stop at 14.6V, so you can plug in overnight without worry. Variable chargers (10A–30A) let you set the current your battery maker specifies — useful for large tubular banks and deep-discharged batteries that need a gentle start. Automatic for daily use; variable for big or stubborn batteries.
Yes. All eight chargers accept 160–280V AC input, so they keep charging through low-voltage evenings and generator supply — a common failure point for cheap chargers that expect a stable 230V.
On the two automatic models and on every model with Float (10A analog, 10A variable, 20A FCBC, regeneration) — yes. They hold a safe float around 13.5–13.8V or stop at 14.6V. On plain variable models without float, disconnect once the ammeter tapers to near zero.
SMPS chargers (all eight here) are lighter, run cooler and hold their output across a wide 160–280V input — far better suited to Indian mains than iron-core transformer units. High-frequency models like the 15A and 20A also charge more efficiently and show live current digitally.
Rough math: Ah ÷ amps, then add ~20% for the taper. A 60Ah car battery on the 6A takes about 10–12 hours. A 150Ah inverter battery on the 15A takes about the same. The 30A roughly halves the time on a 200Ah+ bank. Overnight charging is normal for tubular batteries.
That points to sulphation — sulphate crystals hardening on the plates, which ordinary charging can't remove. The 15A Regeneration charger applies controlled desulfation pulses to recover capacity, then its Maintenance mode float-charges the battery. If it still fails after regeneration, the battery is due for replacement.
