67 Watts Of Power How Long To Charge 12 Volt 600 amp battery?

I have 67 watts of available power, how long will it take me to charge a 12 volt battery with 600amps?

Assuming your battery has been completely discharged, it is capable of storing

P = V x A = 12V x 600A = 7200 W

Assuming no losses (accounting for the internal resistance of the battery) meaning your 67 watts is totally transferred to the battery, need to know the rate that 67 watts is available, is that per second, or hour? assuming per hr

7200 w / 67 (w/hr) = 7200/67 hr = 107.5 hr
