anybody know how to resurrect a dead motor cycle.
apparent it sat around too long.
Voltage is about 8 volts open circuit.
Won't take a charge.
Is it just trash?

I've been told to clamp it in a paint shaker for a few minutes. This is
supposed to break up the sulfate crystals....

That interesting. Thanks. I'll give it a try.
BTW I have not been running the RV4 lately so that scared me and I took
the batteries out to trickle charge them. They both appear to be still OK.

I use a Batteryminder. It has "High-frequency pulses safely remove
sulphate from battery's plates that prevent the batteries from holding a
full charge". Makes batteries last a very long time.

What is the amplitude (voltage) of the pulse and the frequency?

Somebody needs to put a O-scope on this technology.
http://batteryuniversity.com/learn/article/sulfation_and_how_to_prevent_it/
"Permanent sulfation sets in when the battery has been in a low
state-of-charge for weeks or months. At this stage, no form of
restoration is possible."
"Several companies offer anti-sulfation devices that apply pulses to the
battery terminals to prevent and reverse sulfation. Such technologies
tend to lower sulfation on a healthy battery but they cannot effectively
reverse the condition once present. Manufacturers offering these devices
take the “one size fits all” approach and the method is unscientific. A
random service of pulsing or blindly applying an overcharge can harm the
battery in promoting grid corrosion. Technologies are being developed
that measure the level of sulfation and apply a calculated overcharge to
dissolve the crystals. Chargers featuring this technique only apply
de-sulfation if sulfation is present and only for the time needed."
I guess they are junk at this stage.
