Are you sure that this cell can supply 6V at the same time generating
60mA in full bright sun?  Some companies use the marketing approach to
say that their solar cells can produce (for example) 6V / 60mA, but they
use to constantly forget to print the words "whatever is higher". Some
of those cells can generate 60mA at full bright sun, but when consuming
this current its voltage output would be lower than 15% of the unloaded
voltage.

Even that your cell can generate 6V @ 60mA, I think there is a problem.
Lead Acid batteries require that the charging voltage should be a little
bit higher (20%) than its nominal voltage.  I could be wrong, but to
recharge the lead acid battery (6V @ 9.5A) I have in the bench, I should
apply at least 8V @ 1A during hours (voltage measured on top of the
battery), since with only 6V it would never reach full charge.
