I have used the Battery Tender 021-0128
I keep it plugged in ALL the time. Have used this model for twelve years.
Jeff,
Looking for some clarification.
Was the Battery Tender described using over a twelve year period on the same battery? Was that battery an Odyssey PC680 by chance or something else?
This is what they recommend:I'd contact Odyssey and see what they say. I don't think they recommend battery minders, they do have a process that will sometimes rejuvenate a battery and, the last time I looked, they identified chargers that charge the battery to their specs.
Sorry, shouldn't have used "rejuvinate". The procedure was to desulfate the battery: http://www.vansairforce.com/community/showpost.php?p=839509&postcount=1. Don't know if that's useful for you.This is what they recommend:
CTEK (56-864) MUS 4.3 12 Volt Fully Automatic 8 Step Battery Charger.
It is available on Amazon. Very reasonable.
They do not advise "rejuvination" by ANY chargers, due to issues with heat management. Therefore, they recommend using only the "snowflake" mode, when using this charger.
I've owned one for 3 years . . . a great (little) portable charger that goes with me on every cross country trip.
Thanks Tom.Sorry, shouldn't have used "rejuvinate". The procedure was to desulfate the battery: http://www.vansairforce.com/community/showpost.php?p=839509&postcount=1. Don't know if that's useful for you.
Also, approved chargers: http://www.odysseybattery.com/documents/ODYSSEY_approved_12V_chargers.pdf
I purchased the Odyssey OBC-12A charger to charge the PC680 and one feature it has is a built in extended maintenance mode.
I don?t have the manual in front of me at the moment, so I will paraphrase from my not so fertile memory ? If memory serves me correctly, the manual says after the charger has stepped through its various phases of charging and the battery has obtained a full charge, if the charger is left on the battery, the charger automatically switches to a float/maintenance mode.
In addition, if the charger is left connected to the battery for an extended period of time, eventually the charger will turn itself totally off for a month ? then will turn itself back on and go through the charging phases once again. Apparently, this prevents damage to the battery from being kept on a constant trickle charge and keeps the battery conditioned properly.
Happy flying,
