battery assault

A coupla years ago I scored a 24v B&D electric mower off freecycle. I
normally use a reel mower but the electric is useful at times:

* can collect clippings to alter the green:brown ratio in my compost piles.
* can mow down tall stragglers in the yard the reel mower pushes over.

The electric has never been 100%; the donor said he put fresh batts in
it but I suspected them and the braindead charger that comes with. He
suspected the motor's brushes so I pulled them and touched them up with
a file.

I finally bought some replacement 18A 12v for the mower; they are wired
in serial when installed. Before installing them I charged each
seperately with a Battery Tender Plus 12v unit so they would be closely
mated, voltage-wise. Then I connected them and installed them in the
mower. I put them on the all-singing, all-dancing 24v BatterMINDer
charger (queue angelic voices) until I could test drive it.

Mowed some deep grass in the alleyway since everything was short.
Worked great. Composted the clippings and back on the 24v charger it
went. I feel good about this.
