GENIUS10, 10-Amp Fully-Automatic Smart Charger, 6V and 12V Portable Battery Charger, Battery Maintainer, Trickle Charger, and Battery Desulfator with Temperature Compensation

Muito bom!

Even I got issue with the item, they sent a new one to. Thanks!

I just bought this after researching what is the best battery charger or maintainer for owning a Riptide pool vacuum system. This is for personal use and not running a business. Advice for new pool owners or even existing ones, do not buy a junky 500-1500 dollar pool robot, but a hammerhead or Riptide vacuum. Long story short I bought this maintainer to charge the vacuum battery and maintain it between uses. Charged it in no time and I also use this for my Yamaha 700 ATV. Fantastic unit. Only regret is before I opened this, I didn't test it on an ATV battery that died on me to test it's recovery mode. Chance are that I gave the kid at Advanced Auto parts a free ATV/motorcycle battery because if he had one of these NOCO 10s, chances are he saved the battery and got new life into it. Cant go wrong with this especially for the fast charging, force recharge mode, and versatility to charge, maintain, and breathe batteries back to life. Just one more thing, First time charging the battery after sitting idle for 3 weeks and 2 uses in my case and charged it to full literally in 5 min. I like the unit for keeping the battery at full between uses and not overcharging costing me $300 for a new battery. Well worth the money for less worry and hassle. Hope this helped someone with whatever they were looking to use this for. Also cable length is more than sufficient. Im sure there's an extension option if needed too.

Brilliant bit of kit. Essential for my ancient Range Rover.

42 years as a mechanic and I have to say I’ve used all kinds of chargers in my life, and the Noco genius is absolutely the top tier of all. set it and forget it. The smart feature of the charger does it all for you. Today’s batteries are quite sensitive to voltage whether it’s a lead acid or an AGM battery too high voltage or too low of voltage output from a charger you don’t realize it, but it will damage the batteries as it charges. AGM‘s are especially sensitive to this. When charging the Noco automatically adjust voltage output and the amperage output as the battery begins to top off preventing damage and allowing the battery to top off fully at its maximum capacity, which is very important on lead acid batteries. This is where cheap to mid range battery chargers don’t work properly. They often continue to flow even when the battery is topped off at quite a high voltage damaging the battery. This charger also incorporates a desolfation mode that can bring most discharge batteries back to life it also incorporates a forced charged mode that will allow it to charge a battery that is down to one volt which most other brands of chargers will not do smart charger or not. These chargers are very well-made. The plastic is not cheap and is very strong. It has good weight to it. The power cable leads our 16 gauge so they are quite thick. The clamps are copper that is plastic covered, but are extremely solid and durable I’ve been using them for years and have never had an issue. The ambient temperature sensors on these chargers are also another strong point as they actually work properly, allowing a battery that’s in a vehicle in cold weather conditions to top off faster and better and then it will keep it there ensuring a strong start to next morning. For those that want the very best charger that will outperform anything else in its category look no further this is the one along with the three-year warranty that backs it up if something should go wrong. I highly recommend this product. You will not be disappointed so spend the extra money and get the best. You’ll have it for 20 + years
