NOCOGENIUSPRO25: 25A 6V/12V/24V Professional Smart Battery Charger – Maintainer, Desulfator & Power Supply with Overcharge Protection & Thermal Compensation – for Lead-Acid & Lithium Batteries

The Perfect Charger. This charger will supply a continuous 25a if your battery can take it, unlike the others that say 40 amp boost but then charge at a max of 6 amps. The Genius Pro will charge about whatever you put it on and probably the safest charger out there as well. Those who give negative reviews saying short battery life has no idea what their buying, it has no battery… it’s a charger not a car jumper

I bought this to have a bigger version of the NOCO genius 5 that I already had. I use these to repair batteries. I was extremely skeptical about "repairing" batteries but it does work. I had a powersports battery that would only hold 3v. So you could charge it and it would be 12v but overnight it would drop to 3v. It took about 7 repair cycles, but that battery now holds 12.7v overnight. Not all batteries can be repaired.Also, this is good for maintenance. If you have batteries that sit for extended amounts of time, running the repair on them helps keep them in top shape.

Got this charger to maintain a 12v LiFePO4 battery. When electrical power is lost to the charger, it often "forgets" it was in a charge mode and just lets the battery run down. Very inconvenient and expensive to not do its one job. I have two cheaper NOCO chargers for standard 12V batteries that don't have this problem.

Noco quality very powerful Great chargers many options, good circuitry, nice wires, heavy duty, heavy duty not a misprint. if you need a charger this large it will definitely fill the void. Forget about the old chargers back in the day! Great product. thank you.

Great charger for all batteries. It is a must for lithium.Well built with outstanding quality and connections.Highly recommended

Excellent product and seller.

The container comes with an assortment of European power cords. What a waste! This is not a travel kit, it goes into a shop or garage and stays there, in one country. The power cord could be a couple feet longer. The extension cord on the low power side is well made. However, it should have a lock function or be more difficult to disconnect / pull out. The rather fancy soft transport case should have been made to be able to leave the power cords attached! I am very disappointed that an internal fan was required too cool the unit. This is a point of failure, especially when the unit is used on the go, occasionally dropped or handled somewhat rough like normal in a shop. It should be ok if mounted to a wall or kart, but oily dust will eventually clog the darn fan, requiring cleaning. The fan is noisy, but that should not present an issue in a garage or shop. I do like the post clamps. They grip and stay.

amazingly nice product... NOCO has been flawless on every item i have purchased from them!
