Sealed Lead Acid Battery Voltage Chart

Otherwise voltage values can fluctuate based on whether the battery is being charged or discharged.

Sealed lead acid battery voltage chart.

Here is a chart from mk battery showing different levels of charge for flooded lead acid and sealed batteries open circuit voltage. So between 50f and 80f could have a 10 difference in charge state. Secondly pulling voltage down to less than 50 remaining capacity permanently devalues the battery. They are readily available and low in cost.

A fully charged lead acid cell has an electrolyte that is a 25 solution of sulfuric acid in water specific gravity about 1 26. Do remember that battery voltage readings are temperature dependent. Battery has the ability to recover from excessively deep discharge. As mentioned there s 4 main types of conventional deep cycle battery sealed lead acid flooded lead acid gel and agm.

Not every manufacturer makes every size but if you find one you like we can source it for you. For really serious work advisable to take temperature of the battery acid for standard lead acid batteries.

Voltage while under discharge battery state of charge soc in percent battery voltage in vdc 9 0 9 5 10 0 10 5 11 0 11 5. This chart represents the average maximum discharge current ratings for the most common brands of sealed lead acid batteries. Charging current at a beginning is 5 amp. Easy handling no special handling precautions or shipping containers surface or air are required due to the leak proof.

What will be current at the end of charging. Sealed lead acid batteries are widely used but charging them can be a complex process as tony morgan explains. A fully discharged lead acid cell has 12 volt lead acid battery state of charge soc vs. 100 ah battery 50 ah available capacity 2 amp draw 25 hours usage.

This chart was created to be a quick reference to the most common ones. This chart applies to 12 volt sealed lead acid sla batteries. Most manufacturers of sealed lead acid batteries have similar battery sizes which makes product development with slas very convenient. Simple constant current constant voltage chargers will do the job.

For the exact maximum discharge current rating of a specific battery brand contact the distributor or manufacturer of the battery. Charging sealed lead acid sla batteries does not seem a particularly difficult process but the hard part in charging an sla battery is maximising the battery life.
