The calculator will calculate the time after you enter the battery rating capacity, charge rate and the efficiency of the charging system, including the battery. The normally accepted standard for efficiency loss is 20%-30%.

Sample values for a car is 60ah and 0.8A for with the Optimate 4 charger
Sample values for a Motorbike is 20ah and 0.6A for with the Optimate 3+ charger


Battery charge time calculator

 

This is the time taken to recharge an absolutely flat battery
Battery capacity Amp hour (Ah)
Charge rate Amp (A)
Between and hours.

Calculation based on a 70-80% charging Inefficiency

We need a charger that can charge multiple batteries at a time and has a voltage range from 12-24v. And preferably a mobile unit. Please email me with any info you have and if you cannot help me, would you be able to give me details of someone who can.

This surge of current is needed to turn the engine over during starting. Once the engine starts, the alternator provides all the power that the car needs, so a car battery may go through its entire life without ever being drained more than 20 percent of its total capacity. Used in this way, a car battery can last a number of years. To achieve a large amount of current, a car battery uses thin plates in order to increase its surface area.

A deep cycle battery is designed to provide a steady amount of current over a long period of time. A deep cycle battery can provide a surge when needed, but nothing like the surge a car battery can. A deep cycle battery is also designed to be deeply discharged over and over again (something that would ruin a car battery very quickly). To accomplish this, a deep cycle battery uses thicker plates.

The power is in standby mode and will only kick in when the mains fail.

The advantage of our system is that you do not need to manage the power as it manages itself and does not waste electricity. The system can also use bigger batteries, is much more maintenance free, and the battery lasts a lot longer than with the traditional UPS systems.
