My 2008 Cougar that I bout a couple weeks ago has what I assume is the original Pro Pack III charger. I noticed only the bank 1 lights working. The charger has been plugged in since Saturday night after fishing. Battery 1 – AGM – 12.47 with charger and 11.83 and falling without.Battery 2 – Lead Acid 1 – 12.61 with and without charger. Battery 3 – 12.54 – with and without charger. I assume the battery 2 and 3 have charged since running them all day Saturday. Battery one is definitely charging but I dont know why it is falling off so fast after unplugging the charger. Does it appear to yall that it is working despite no lights on 2 and 3? What would be the most direct replacement?

Battery one is suspect especially if there wasnt a load on it. Be worth pulling it and having it load tested. The other two fish them all day so they will be somewhere south of twelve volts and take your voltage readings before and after plugging in the charger. Then youll know.

Charged batteries should read around 12.6 volts after an hours rest from charging . — Should not drop off . — Bad cell in battery 1 would be my call . — 9 year old charger ……. ??? — Best course of action is as stated above — Fully charge batteries / let rest one hour / load test all . — Replace as needed , along with the charger . — Just my humble opinion after 46 years of automotive repair . — Hoss
