CTEK CS ONE Gen 2 Battery Charger 12V 8A IP65

CTEK CS ONE (Gen 2) — Polarity-Free Smart Charger with App (12V)

CTEK’s flagship, built to take all the guesswork out of charging. The CS ONE’s headline feature is its polarity-free clamps — black on both ends, so there’s no positive or negative to get wrong; connect either clamp to either terminal and the charger sorts it out. Combined with APTO adaptive charging, which automatically detects your battery’s type, size and condition and builds a tailored charging program, it’s about as foolproof as a charger gets — including for 12V lithium (LiFePO4).

The Gen 2 version adds Wi-Fi and Bluetooth connectivity via the CTEK app, unlocking extra functions — RECOND for reviving deeply discharged batteries, WAKE UP for batteries protection circuits have shut down, and SUPPLY mode — plus live charging data at your fingertips. At 8A across a 3–180Ah range, it covers everything from a bike to a large car, boat or caravan, and regular use can extend battery life up to three times. IP65-rated for garage and outdoor use.
