We have provided our visitors with a free to use battery backup time calculator, to check expected backup time for your battery, our backup calculator assumes a default value of 70 percent efficiency or 70% Depth of discharge (DoD) of battery to calculate its total backup time, we considered 70% as the worst case scenario for the final duration of battery backup time in our calculator. we would like to note that all calculations are accurate and valid, if you need more clarity seek professional advice from your engineer or contact us.
