Outperform and outlast most competitors' batteries - it's a fact!
There are three battery types that are marketed as "maintenance-free" - low-antimony, hybrid and Nissan's calcium battery.
In every meaningful test, Nissan and PowerMax maintenance-free calcium batteries simply outperform both low-antimony and hybrid batteries.
Many battery manufacturers continue to produce batteries containing antimony, only because it's cheaper. Nissan Maintenance-Free Calcium Batteries provide superior performance, long service life and true dependability at very competitive prices.
After a 12-month stand, a calcium maintenance-free battery actually gains cold cranking power! A hybrid type loses almost 9% of its capacity, while low-antimony types lose 12%. This is especially significant for the lower-capacity batteries.
While in storage, without recharging, a calcium battery retains most of its capacity, whereas hybrids lose more than 65%, and low-antimony, 95% of their reserve capacity.
In fact, after 12 months without charging, low-antimony and many hybrid batteries will have to be scrapped, while the Nissan Maintenance-free calcium battery recharges nicely with no loss in capacity.
A hybrid battery gasses (loses water) at a rate six times greater than that of a calcium battery. A low-antimony battery gasses at a rate twelve times greater than that of a calcium battery.
Less water loss = Longer service life
