Charge it, fix it, forget it.
A household charger that behaves like a technician. The NQ/NS series detects the battery, applies the right 3-stage profile for lead-acid or lithium, lets you dial the current for bank size, and even runs a repair cycle to recover sulfated batteries — all with electronic protection on every connection.
STD/AGM programs at 14.4V/14.6V and a lithium program at 14.8V, each with correct float voltages — one charger for every battery in the garage.
Step-selectable output (e.g. 2/5/10A on the 10A model) matches small starter batteries and large service banks alike.
A controlled desulfation program recovers neglected lead-acid batteries, restoring cranking performance before you buy a replacement.
Reverse-polarity protection, over-temperature shutdown and -40–85°C storage tolerance make it safe for any household.

Yes. The 3-stage algorithm ends in a float stage that holds the battery at a safe maintenance voltage (13.8V for STD/AGM), so you can leave it connected for the off-season.
Repair mode applies pulsed desulfation to lead-acid batteries that have sat discharged and lost capacity. Run it when a battery accepts charge but will not hold it — it often restores usable capacity and delays replacement.
For lead-acid, 10–15A (10–15% of capacity) is the sweet spot — the 1210 or 1215. Lithium banks accept more: match the current to 0.2C of capacity and use the lithium profile.
