Another Novice Q. - recharging - Volts and Amps

Apologies in advance if this is a dopey question, but, when it comes to 
recharging batteries, and using a solar cell to do that, what I've been 
assuming, based on th info that peopl ehere have kindly provided, and also

that I've foind on-line, is that teh mA output of the solar cells should 
not exceed 2/10ths to maybe 3/10ths of the battery's mA rating, and teh 
voltage produced by the solar cells should be as close as possible to the 
total voltage of the battery or batteries.  But I wanted to check whether 
that assumption is correct, becasue I think I'm getting closeto getting 
some parts and trying a couple of assemblies.

Thanks In Advance!
