About this item

  • Meet the GENIUS2DAU - A direct-mount onboard battery charger for an under-the-hood battery charging. It's the all-in-one universal charging solution - battery charger, battery maintainer, trickle charger, float charger, plus battery desulfator.
  • Direct Mount - Securely mounts nearby the battery with its rugged snap-fit mounting bracket and effortlessly installs into most materials with truss-head self-tapping screws.
  • Do more with Genius - Designed for 12-volt sealed lead-acid automotive, marine, RV, and deep-cycle batteries, including flooded, gel, AGM, SLA, VRLA and maintenance-free batteries.
  • Enjoy precision charging - An integrated digital thermal sensor detects the ambient temperature and alters the charge to eliminate over-charging in hot climates and under-charging in cold climates.
  • Charge dead batteries - Charges dead batteries as low as 1-volt. Or use the all-new Force Mode that allows you to take control and manually begin charging dead batteries down to zero volts.
  • Restore your battery - An advanced battery repair mode uses slow pulse reconditioner technology to detect battery sulfation and acid stratification to restore lost battery performance for stronger engine starts and extended battery life.
  • Beyond maintenance - It's not just a battery trickle charger, it's an advanced battery charger maintainer. A fully-automatic, worry-free smart battery charger for everyday use - 24/7 - with zero overcharge.
  • Compatible with all types of petrol and diesel vehicles - Add a permanent onboard battery charger to any vehicle, like cars, automobiles, lawn mowers, ATVs, UTVs, tractors, trucks, SUVs, RVs, caravans, trailers, boats, PWCs, jet skis, golf carts, classic cars, and more.

Fitted into the side wall of the engine bay next to the battery work very well providing a trickle charge to keep the batteries fully maintained. Small compact easy to use and do the job. I'm happy with it.

Small and compact, it has been keeping the battery on charge now for a couple of months with no issues.
The thing I would of liked is a removable power cord so the unit can be mounted with out the cord hanging around.

I generally prefer the CTEK but this one is good and much cheaper. Plus I had a terrible time with CTEK warranty through Repco when I had a broken one. Despite the 5 year warranty Repco wanted to jerk me around because I didn’t have the receipt. Not making that mistake again and ordering from Amazon instead 👍🙂👌

I was able to connect it to the battery in a few minutes and tape it somewhere. Didn't use the mount included as my battery is in the trunk.

I bought this unit for my sister as a gift. I have four of Noco chargers and they all work perfectly. Unfortunately, this particular 2 amp one wouldn't turn on, so we will have to return it and ask if you will kindly replace.
