Noco chargers are not fast not even remotely, Using the 26Amp Noco on a 115 Amp Battery Vs a 10Amp standard type charger and the Standard Charger will Blitz the 26A Noco,
How do I know this ? because I own the Noco G3500 / 3.5A charger and the G15000 / 15Amp Charger and the G26000 / 26Amp Charger, All three of them are very slow indeed
IE, I hooked up the G15000 to the 115A/h battery to charge it and it took 8 and a half hours to get to 90% where the Main Green Light was flashing and by time it had finished doing what it had to do once the Green light came On fully the charger sat there clicking away equalizing the battery and by time it had finished over 39 hours had gone by,
I spoke to Noco and I got a heap of Techno babble which was totally BS, As I have 3 new batteries and on each battery the results were the same, Anyway I don't know how they can claim that they are twice as fast on a 100/120 Ah battery claiming it takes 3.8 hours to charge a Deep cycle Lead Acid Battery Because the quickest I have seen the Green LED light up fully is 6 and a half hour, and my Big Normal charger on the 9Amp setting will charge the same battery in 3h 30m up to 4h 37m.
The only thing Noco chargers are good for is leaving batteries permanently on charge along with being able to charge many different battery technologies, I just don't see a real world purpose for Noco Chargers apart for leaving a battery on charge forever. I fell for their BS and it has cost me about $600 bucks to know the truth. I hate liars and conmen.
