VPC - Voltage Per Cell, Minimum allowable volts per cell.
You can check the left side of the page 6 from this.

Thank you ScottWang

This might be a dumb question but...
Can I use this information to tell me how long it would take to charge the battery?

VPC is using to describe the numbers of battery, and the minimum allowable volts for each cell.

For the Lead Battery charging time:
When you first times to charge the battery, then you can using 0.1C or less to charge the battery.

The normally charging time is 0.3C.

C is the current of battery, assuming the current are 7A, exp : 7A*0.3 = 2.1A, it means that the Imax for charge current.

ok I kind of understand you
Im now stuck on trying to find out how long it would take to charge the battery.

I have purchased the BEG120120 battery and I have a solar panel which I will be using to charge the battery. I am trying to work out how long it would take to fully charge the battery.

Do you have any ideas on how i could go around this please?
