Can I estimate recharge time for a given battery and charger?

You can estimate recharge time by dividing the amps to be replaced in the battery by the charger amp output. For example, you have a 100 amp hour deep cycle marine battery that is 50% down, therefore giving you 50 amps to replace. If you have a 10 amp charger, you divide the 50 amps by the 10 amp charge rate of the charger, and get 5 hours.

In reality, the multistage chargers taper the current after about 80% to 85% of the bulk charging is done, so it takes a little longer (closer to 6 hours in this case). More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
