Lead Calcium Battery Discharge Curve

Because of the use of lead calcium alloy for the electrode in lead calcium batteries they have a low self discharging effect and a longer service life than the lead.

Lead calcium battery discharge curve.

The key difference between lead acid and calcium batteries is that the lead acid battery has a lead electrode inside the battery whereas the lead calcium battery has calcium along with lead as the electrode inside the battery. Depth of discharge also known as dod shouldn t be any more than 50 in most deep cycle batteries in order to get the best value for money. I offer these graphs as examples of what to look for with your battery. Soc points will vary from battery type to battery type the shape and relationship of the curves is similar for all deep cycle.

Batteries lead calcium cells and rv deep cycle batteries will have different charge discharge curves. When the battery is discharged water is produced diluting the acid and reducing its specific gravity. Kcr lead calcium kar lead antimony for switchgear and control applications capacities from 200 to 825 ampere hours h l w features benefits electrical testing to 100 capacity on every battery string prior to shipping assures performance of every battery string upon delivery long life positive plates cast with a proprietary process and. While specific voltage vs.

Antimony alloy with lead iv oxide pressed into it although batteries designed for maximum life use a lead calcium alloy. At the negative plate sponge lead pb is converted to lead sulfate pbso 4. Relationship between battery capacity temperature and lifetime for a deep cycle battery. Battery failure rates as defined by a loss of capacity and the corrosion of the positive plates increase with the number of discharge cycles and the depth of discharge.

Depth of discharge is a very important calculation you should make when choosing the size of a deep cycle battery. During the discharge portion of the reaction lead dioxide pbo 2 is converted into lead sulfate pbso 4 at the positive plate. Figure 3 lifetime curves temperature discharge cycles. This causes the sulfuric acid 2h 2so 4 in the electrolyte to be consumed.

The negative electrode the cathode is made from pure lead and both electrodes are immersed in sulphuric acid. The discharge voltage curves of li manganese li phosphate and nmc are very flat and 80 percent of the stored energy remains in the flat voltage profile. Chemical reaction when a battery is being discharged. So if you have a 100 ah battery consider the cut off discharge depth being 50 ah.

Longer discharge times give higher battery capacities.
