• Battery type & application

In hybrid batteries we see a combination of the cyclic performance of the lead-antimony batterie and the low self-discharge of its calcium counterpart:

• a positive plate of low antimony alloy for better resistance to deep discharge
• a negative plate of calcium alloy to improve shelf life (approx 6 months)

The hybrid construction proves very succesful for commercial and dual purpose batteries.

Hybrid batteries cannot be produced dry charged.

In the trade these batteries are referred to as PbSb/SbCa
