These days of electric panels, one may be assuming a significant risk taking
off after jumping a dead battery.
Considering the availability of batteries like Odyssey (they hold 90% of
their charge after sitting for 6 months), the only way to get a dead battery
is to leave something on or a problem with the charging system. Either way,
the battery should be considered damaged until you can do a recovery and
subsequent test discharge, or better yet just replace it.
The bottom line (my opinion), jumping dead batteries went out with battery
boxes to collect acid overflows. Send the extra weight back for a refund.

Subject: Jumper plug and recepticle.
Some good advice would be appreciated.
A few weeks ago I saw a post about Aircraft Spruce's jumper plug. I placed
an order for several items and bought this too. I am quite surprised by the
quality of this unit as it looks like a unit one would find on the
underbelly of a commercial airliner. My problem with it is that it weighs 1
pound seven ounces and that does not include the cable which needs to be
attached to the plug.
This is quite an large heavy item.
Being a sailplane pilot I have not had the issue of going to my plane and
finding a dead battery. I don't need a jumpstart to fly, I need a towplane
and a good thermal day.
People who fly powerplanes, how often does a plane need a jumpstart or a
serious battery recharge?
I am seriously thinking of returning this item.
Thanks,
