NOCO GENIUS2: 2A 6V/12V Smart Battery Charger – Automatic Maintainer, Trickle Charger & Desulfator with Overcharge Protection & Temperature Compensation – For Lead-Acid & Lithium Batteries

Bought a campervan last summer to use over the weekends and decided to get a tracker/immobilizer for it at the same time. What they didn't tell me is that this little safety feature likes to drain the battery. Over late autumn/winter my battery used to get drained in under 3 weeks. Finally decided to buy this trickle charger and now my my battery is nicely topped up all the time. Easy to use, small enough so that it permanently sits under the hood connected to the battery, and has all the features I could want, supporting multiple different battery types, so I can use it with the other vehicles in the family if I wanted to. It's a little bit pricier than other ones on Amazon, but googling the make shows the NOCO GENIUS chargers consistently in the top 5 available in the UK.Been using it now for a few weeks and will recommend it to anyone.

This has been one of the best things I've bought recently. My car battery isn't in the best of shape and this charger has reconditioned it to be much more reliable than it was. Brilliant purchase and a great price too

Easy to use. Does the job. Big difference to old style charger

Great little battery charger, got to charge a lithium motorbike battery, works brilliantly!Have since ordered the x connect cable to attach to the battery for quick connect.Would highly recommend.

The Good- Incredibly easy to connect- Instructions are clear- Waterproof (Tested - As seen in pics)- Great Value compared to competitors- Reputable brand- Solid feel and designThe Bad- The cable isn't quite as long as it could be. It's a good length but 2 or 3 extra feet of length from the box to the plug would be ideal. Reaches the garage fine though (as seen on pic)- No carry case included which would have been handy as there's a lot of cable- Charging can take a bit of time (15 hours in total for my totally dead battery)- 40ah maximum charge (larger more expensive units can power more)The VerdictI would highly recommend this item. For the price paid it is a fantastic product that does exactly what it says. It fits my need (keeping a 65ah car battery alive during periods that i am no longer driving it as much). If you want faster charging or a larger refill need then perhaps look at the higher tier Noco Genius units. But for an overnight plug in and forget device that means that your battery doesn't run flat between runs you cant go wrong with this for the price.

Convenient and handy. Very powerful (jump started my dads tractor!). Good value for money.

Battery totally flat.I'd bought one the previous. Didn't charge at all so I returned it.Bought this one and it took about 6 hours to fully. I've been checking the battery daily with my multimeter..Voltage is stable

Purchased in November 2023.Used it in the garage to charge motorcycle battery a couple of times before it failed (May 2024). Noco did replace it under warranty.I have just used the replacement for the 2nd time to find its failed in the same way. All the LEDs flashing and no operation.2 failing in the exact same way.I would recommend choosing a different brand as these are obviously not fit for purpose.
