Re: (ET) Ryobi mower
If that's the Ryobi BMM 2400, you should know there is a fuse internal to
the case in the charger circuit that blows regularly. I used to think it
blows when there's a slight surge in the line voltage, but I suppose it
could be when there's a sag and the current draw increases? Don't quote
I'm a sw eng not an ee.
I forget the details of the fuse (value, size, etc.) but I replaced mine
with a panel mount fuse holder that I mounted through the back panel next
the charger line cord input. THen whenever it blew I could replace it
without taking the cover off the mower and the internal cover off the
charger circuit. Whatever engineer signed off on that design/assembly
should have his credentials examined. I'd bet that arrangement is the
reason Ryobi bailed out of the cordless mower biz., too many warranty
for a blown fuse.
The 24V 18Ah batteries are hard to find ( = pricey) but easier to find are
pair of 12V 18Ah in 1/2 the form factor, so you just duct tape or tiewrap
them together under the original tiedown, or get more creative. And of
course add a jumper from one - to the other +. I saw them listed for
$35 each at gotbatteries.com yesterday...(Powersonic 12 Volt/18 Ah
So maybe the battery is fine and the charger circuit has a blown fuse.
if that's the case, $50 is a good price for that machine.

Looks like I've got a cordless Ryobi with a defunct battery, anyway it
won't charge up. If anyone wants to pick it up here, cost will be $50,
looks to be in good shape otherwise.
I really don't need it as I've still got the B&D.
