calcium-calcium battery

The next stage has dominated on a wide front in recent years and is called Calcium-Calcium. The calcium-calcium battery involves the antimony on both the negative and positive plates being replaced by calcium alloy. The benefits are obvious. The fluid loss of the calcium-calcium battery is about 80 % lower than that of an antimony battery and the self-discharge is lower, i.e. a calcium-calcium battery can remain unused for longer periods without losing a lot of their charge. The disadvantage is that the calcium-calcium battery is more demanding when charging if they have been over-discharged.

Efforts made in avoiding the gassing had a positive affect, namely that the bubbles moved about in the acid causing it to be thoroughly mixed when charging. Without these bubbles the acid can stratify at different densities, acid weights, and is quite a common phenomenon. An acid weight of 1.35 or more at the bottom and maybe 1.17 at the top when you are looking for an even weight of 1.28 may cause the calcium-calcium battery to be affected by sulphating and increased grid corrosion despite the calcium-calcium battery being apparently fully charged.

Prevent this by using a maintenance battery charger, that can be connected for a long time. Make sure the calcium-calcium battery is connected to a battery charger whenever it isn't in use. You will extend the lifetime of your calcium-calcium battery if you keep it fully charged.
