what does is maximum permissible current means? Is it in ampere or milliampere?

 

[tpetar]

Its maximum allowed discharging current for 5sec (300A).

Unit is Ampere.

Its in Ampere

These batteries are deep cycle type, and have capacity rating declared in C/20, that means capacity is declared if you discharge battery for minimum or over 20h.

If you try to discharge batteries with very small resistance and with higher amperage over 300A, batteries lead plates can distort.

Starter lead acid type can give you more starting amperage but they are NOT for deep cycling up to 10,5V.
