Just got one brand new in the box. Opened it up and stuck a meter to
it. 12.87 V. What is the ideal voltage for it to be at if it's not
going to be used for a month or so?

I have about 30 680s here when they 1st came out of the box their resting
voltage uncharged was 12.85 to 12.90.I have about 130 passes on them and their
resting voltage after being on the shelf for 3 months is 12.97 to 13.01.

I run Genesis Hawker G12v16Ah10EP.

After a full charge they set at 13.05 volts

After sitting a few days, 12.84 looks like a full charge.

I always have leakage or controller drain.

Can'say after a week what they look like ?

Should I adjust my voltage or leave it be at 12.87?

On my current eliminator dragster and my smoke screen S10,I bulk charge to
14.1 volts per battery at the track. At home after a day or so I put the
batteries on a balance charge at 14-3.I have gotten as many as 625 cycles drag racing
my dragster and the hawkers keep putting out as they did at 50 cycles. The
truck now has over 400 hard running miles with its longest run now over 37miles
on 1 string of 26ah hawkers. Resting OCV after being charged (resting 24hrs)is
13.01 to 13.04. Dennis Berube

Charge 'em up. Typically you are advised to not let AGMs self-discharge
below 12.8V when storing them. 12.87V is close enough that you might as
well top 'em up now.

FWIW, I opened the breaker on my 120V back of Optimas Aug 2nd or 3rd
before leaving on vacation. The car has been off the road since waiting
on me to install the new pack, and before starting to pull the Yts last
weekend I flipped the breaker back on to check the voltage, just for
kicks: 130.0-130.5 or 13.0-13.05V average. Your AGMs should likewise
sit very near to 13V each for a long time off charge when there is no
load on them.

Cheers,

Roger.

Dennis;

Can you share some specs on your S-10 truck that your racing.
Looks like you may be using these Odyssey's in it.
