Review: Well worth the money - Excellent bit of kit. Does exactly what you want and the dead battery revive function works superbly. I don't use my hybrid enough for the 12v battery to charge much, so it frequently drops below a voltage other chargers won't detect, subsequently not charging and leaving me with no way to charge it. This unit detects below 1v so allows power to the battery. Small, lightweight and compact so no bulky storage. Easy to use and doesn't create much heat. Highly recommend
Review: Quality charger and all-round battery maintenance - Revivied, restored and charged my motorcycle battery in a few hours and brought it back to tip top performance! Good quality product well made and really good strong sturdy clamps included , simple to use and desulfurization mode worked a treat and cycled through quick enough and charged my battery back to full now after being left out for a month or more in freezing cold storage . Well worth buying and having in the garage

## Questions & Answers

**Q: Will this restore to previous setting and continue maintenance after a power cut? My current one had to be reset each time**
A: It returns to the settings you had before

**Q: Can you use this to jump start a car if the battery is dead with no access to a power outlet**
A: No. The GENIUS5 is a battery charger that recharges a battery only when plugged into an A/C outlet. It is not a jump starter. See NOCO Boost UltraSafe Lithium Jump Starters.

**Q: When using this charger do you need to disconnect your car battery?**
A: For the normal charge mode it should be safe to charge with battery connected but if using the repair mode I think it would be safer to disconnect as it puts out more voltage (over 15v) and could damage any sensitive electronics, like the ECU.

**Q: Ive charged my battery but instead of a solid green light after i have a pulsing green light lasting 2-3 secs. Is it fully charged?**
A: Yes, it is fully charged but leave the device connected unless you need to use the vehicle. Flashing green means the Noco is reconditioning the battery for longevity and easier future charging. After I charged my (knackered) battery, I had flashing green for at least another 24 hours. Leave it, if you can. It will go solid green eventually.

### ⭐⭐⭐⭐⭐ If you are looking for a well made and easy to use car battery charger - this is it!
*by L***Y on 30 December 2024*

I bought this NOCO battery charger to replace an ageing battery charger, and I needed a charger that would be suitable for the newer AGM/ Stop start batteries. Initially I had been given advice to purchase a well known competitor to the NOCO, but as I already own, and highly rate the NOCO jump starter/booster pack, I decided that I would stick with the brand. From the moment you open the box, it's clear to see that NOCO take time and effort to design and manufacture their products. The products are so well made, which make it a refreshing change from all of the usual cheaply produced rubbish that you see. The charger is a sturdy bit of kit and feels it. The battery lead come in two pieces - which is a brilliant idea. It makes it so much easier to attach the battery clamps to the battery, without worrying about the charger banging around behind. Especially as is often the case these days, the batteries can often be buried in the car somewhere. Talking of the battery clamps, they are a perfect size, not too big or too small, and the clamping pressure is spot on. The other advantage of the lead being in two is that you could permanently attach the clamp end to your battery terminals (obviously using the ring terminals instead of the clamps) and then leave the lead permanently attached to the car. It's simply a case then of attaching the other end (with the charger attached) to the lead - perfect if you want to regularly top up your battery. The end you leave on the car has a well made cover that simply attaches over the end and keeps it clean and dry, and the connection between the two leads is well constructed. On to the charger. It's so easy to use. Connect it all up to the battery and turn the mains on. The charger instantly goes on to standby, something that most battery chargers don't do, and I for one think it's an excellent safety feature. Simply press the button to select your battery type and leave it to do its job - it's that simple. The led's are nice and bright and show clearly the charging process of the battery. This is an excellent product and there are many reviews online for you to view before taking my word for it. Well done NOCO, another excellent product!
