OK. We were recently told that this page was missing. Apparently it did not make it from our old yahoo site to the new Big Commerce site I am going to need to learn how to re-create this simple charge time calculator on this page. But, I am not a competent programmer. ;-(

Essentially the formula is: battery capacity divided by charge rate and then multiplied by 1.2 (the 1.2 result gives us a bit of wiggle room to accommodate variables like battery resistance, charge rate reduction when the battery gets close to "full charge", etc.) 

Hmmm... this code is not quite what I had in mind but interesting all the same...and besides I can copy and paste code easily.

Solution is

 

Or, I could include a link to the old page. God only know how this still works, but it does. ;-)

 Darn it, first copy and paste attempt. Looks OK but does not yet work. If at first you don't succeed... To be continued. I just need to figure out what in this mess of old code needs to be copied to this page. ;-)

Battery capacity    mAh
Charge rate   mA
Max time to full charge: hours
