Lithium compatible

Asked by Bk September 26, 2020

Answer

No, it is not compatible with lithium batteries.

If I have a 24v system (2 12v battery) would it hurt the system to use this?

Asked by Seth September 14, 2020

Answer

No. Each 12V battery would be hooked up to its own bank of the charger (leaving one bank free) as though they were charging individually. The batteries themselves can still remain wired together in series.

The green indicator lights does not come on the charger is charging but the lights do not turn from red to green.

Asked by HDS August 31, 2020

Answer

The Charge LED will not turn green until the battery is fully charged to 14.4V. We would recommend verifying the battery's voltage with a voltmeter, and making sure you're seeing an increase in voltage over time. If not, please contact NOCO Support directly for assistance.

Wish I had made this purchase earlier. I have 7 batteries to charge - ranging from recreational vehicles (ATVs) to deep cycle. This takes away all the headaches of rotating batteries through a single charger, and you can just charge one if you want. This thing is a beast too - seems to be well-made and I like that it's waterproof.
