1 year agoI had a CTEK MXS 5.0 and a Noco Genius 10. The CTEK got too warm when charging 12v batteries so i eventualy took it back. IMO it’s always good to have one of these handy just in case. 12v lead acid batteries don’t like to be discharged for long (even a few days) before damage occurs.
I wonder how the Hummer EV would do.
