The WORLD SOURCEONE Difference:
The Calcium Maintenance-Free Advantage

As the Stand Loss chart shows, after a twelve month stand, a calcium maintenance free battery actually gains cold cranking power while a Hybrid loses almost 10% of its rated capacity and low antimony loses 12%. This is especially significant for the lower capacity batteries.

As the In Service Rate of Water Loss chart shows, Hybrid gasses at a rate that is 600% more than calcium maintenance free. Low antimony gasses, or loses water, at a difference of 1200% Conclusion: Less water loss = Longer service life.

The last chart compares the percent of reserve capacity retained, while in stock, without recharging. Compare the rate of decline of the Hybrid vs. Calcium maintenance free after 12 months. While calcium maintenance free retains most of its capacity, Hybrid loses more than 65% and low antimony 95% of its reserve capacity.

• In fact, after 12 months without charging, low antimony and many Hybrids will have to be scrapped, while calcium maintenance free batteries recharge nicely, with no capacity loss.
• Our calcium maintenance-free batteries have a one year plus shelf life which can be an excellent benefit for any seasonal application such as lawn and garden batteries that have to deal with an extended storage period after the point of sale.
