| Subject: | Re: Battery Tender |
Bob,
I had a Deltran Battery Tender Junior on my PC680 for years and it worked fine.
I sold the plane and am not driving my car as often. The Tender Junior max charge
is 750 Ma. When I put it on my car that was just driven it got too hot to
touch in about 30 minutes. Is it too small for the higher capacity auto battery?
I like the specs on the Yonhan unit you showed in your last entry. I plan to install
a plug accessible without raising the hood and putting longer wires with
a plug on the unit. Do you think this is workable??
Thanks for all the help you have given over the years.

Interesting observation which I've duplicated.
With the charger plugged in and the battery fully
charged, the device reverts to what may be their
'pulsed repair mode'. When attached to an 18 a.h.
SVLA battery, the charger/maintainer settles
pretty quickly into a pulsing activity that
oscillates between 100 and 150 mA. I've left
it connected to see what happens over the
next few hours.
When unplugged, the C/M draws a small but
not insignificant 0.025 amps and the
front panel display says lit up.
We'll see where the 'pulse mode' goes
over the next day or so.
I've attached a printout off a charge
profile for the subject C/M and a fully
charged, 18 a.h. SLVA battery.
It appears to perform as expected with
a maintaining voltage on the order of
13.1 volts.
I'll report on further findings as they
prsent.
