A.  Remembering the voltage during bulk mode charging is still 14.4v are indeed charging, but we are also pushing 15 or 25A which is substantial energy into a battery per hour even for the largest 12V...

If you have a battery used in a boat they are typcially 800+ CCA which means they will need to be around the 80Ah or greater. This means you would be operating at the higher side of the maximum perfor...

The Marine series have a night mode which when pressed derates the charging power of the units to 50% so that the units don't get hot and require the internal fan to run. After 8 hours the chargers re...

The units are manufactured in exactly the same way. The M100 gets a marine decal/label with a yacht where as the MXS 7.0 get a car icon. The M100 gets the M10 eyelets with the comfort plug where as th...

When the maximum current output of a charger is less than 1/20th the Ah of the total battery bank size it's trying to charge. It's effectively too small or too low a current to successfully charge a f...

These are both similar terms typically referred to by manufacturers to describe a final stage of charge. One could say the charger turns off or on as needed to keep the battery charged. Others may say...

Yes it's just the harmonic frequency of the pulsing which may be amplified by the surface the charger is resting on.

Yes it is the relay resetting the open circuit mode, just check the terminals are firmly connected to the battery and the noise will stop soon enough

Both of these chargers do not have the mode buttons. That's why the product codes do not start with the "M" like almost all the other chargers in the range. It also means the LED's are only illuminate...

The charger size is best matched to the batteries Ah capacity. If you have a 50Ah battery you need a charger 1/10th the size. So 5 Amps for a 50Ah battery (MXS 5.0) & 10 Amps for a 100Ah battery (MXS ...
