I have a Ryobi BMM2400 "The Mulchinator" that I'd guess is similar.  I 
don't 
use it anymore now I have the E-15, but I used it for 8 seasons with the 
original battery.  I had to replace the internal fuse in the onboard 
charger 
several times and eventually rewired to a panel-mount fuse holder so I 
didn't have to take the thing apart each time.

Anyway, I achieved extended run time by mounting a small, 24V PV panel 
directly on top of the mower, wired in parallel to the battery.  It's only 
a 
little smaller than the mower footprint, which probably makes it a 10 or 
15-watt panel.  It's pretty impossible to quantify the amount of extended 
runtime, what with shadows, time-of-day, length of grass, etc. etc. but I 
perceived a boost, especially when the battery SOC was getting low and I 
wanted to just get those last few passes done.

However, the real answer is an auxilliary battery, right?  Or, do what the 
Neuton (from DR Power Products in VT) does: the battery pack is smaller 
and 
in a cassette that is easily swapped with the recharged pack that was 
sitting in the off-board charger while you were mowing with the first 
pack. 
I got this Neuton mower for my mom two or three years ago (she's 78 now) 
and 
she loves it, and it works great for her 1/3 acre of grass.  Ok, she 
doesn't 
do it all at once, but the swappable pack concept makes the mower lighter 
and it's well engineered.

As far as a better charger, that's not my area of expertise or 
experience... 
good luck and let us know what works

Any ideas on increasing run time or making a rapid charger?
