I'm sure you're right. I was surprised to get anything out of them at
all.
this morning I ran it a little longer, not cutting anything, and the low
power
LED was on the whole time. I did break open the seal on one battery but
filler
holes are tiny, too small for my hydrometer.
This time I unplugged the charger from the 110 wall plug before unplugging
it
from the mower and the red "charging" LED came on. Still don't understand
that...
what are my battery options besides Sears?
ciao,
dave
