Here’s the dilemma. To charge your battery efficiently, you need a relatively high charging voltage (±14.5 V). But if you stay at that voltage permanently, you will overcharge and damage the battery.
Conversely, if you use a lower charging voltage (<14V) you will prolong the battery life but will take a long time to reach full charge – in some cases you might never actually reach full charge!
The solution is an adjustable, multi-stage voltage regulator for your alternator.
The ZM4 smart charger allows you to configure the optimal charging voltage for your specific battery, and after a set time will automatically switch to a lower ‘healthier’ voltage. The best of both worlds!
Typically with automotive regulators the battery acid does not get enough charge and this leads to acid stratification, which is where the water separates to the top and the acid settles on the bottom and in a ‘pure’ acid form will attack the battery plates leading to premature battery failure.Charge voltage is probably the single most important factor in charging, as all other factors are related to it.
