The NOCO Genius10 is a 10A smart battery charger, maintainer and desulfator for 6V and 12V lead-acid and lithium-ion batteries up to 230Ah, capable of recovering batteries discharged as low as 1V. It is part of the NOCO Genius range.
This listing is the Genius10. The NOCO Genius range is also available in 1A, 2A and 5A versions.
It suits automotive, marine, deep-cycle and powersport batteries, including flooded, gel, AGM, EFB and maintenance-free types.
Key specifications

Multi-voltage, multi-chemistry, multi-battery type
Charge 6V and 12V lead-acid and lithium-ion batteries across multiple chemistries — flooded, gel, maintenance-free and AGM — and multiple types, including starter, deep-cycle, marine and powersport.
Powerful, efficient and compact
The Genius10 uses high-frequency switch-mode technology to convert AC power into safe DC power. An onboard microcomputer precisely controls the charging process to minimise power loss, keeping the unit compact despite its 10A output.
Improved start voltage sensor and Force Mode for dead batteries
An improved start-voltage sensor detects and charges dead batteries down to 1V. For batteries below 1V, Force Mode can be activated manually to recover batteries all the way down to 0V.
Improved clamping range, clamping force and redesigned clamps
The Genius clamps feature needle-nose profiles for smaller terminal applications and detachable integrated eyelets for permanent mounting to the battery. They are designed to fit terminals of any shape and size, with improved clamping range, clamping force and higher conductivity.

About the NOCO GENIUS10
From our tech experts at CEN
The NOCO GENIUS10 is the most powerful single-bank charger in the Genius range: a 10A smart charger, maintainer and desulfator for 6V and 12V lead-acid and lithium batteries up to 230Ah. It recovers batteries from as low as 1V, or 0V in force mode, and maintains any size.
Who it suits
Owners of large car, 4x4, marine and leisure batteries who want a quick recharge from flat. For an ordinary car battery the GENIUS5 is usually enough, and for 24V systems or batteries beyond 230Ah look at the GeniusPRO25.
Our tech experts advise
It is rated IP65, weighs 1.5kg and comes with a mounting bracket, strap and screws for a permanent spot in the garage. The clamps have integrated M6 eyelets that can be fitted to the terminals for plug-in charging. The GC040 case fits it.
