The ProPack IV charger on my 2007 Puma doesnt seem to me to be be operating correctly. I can spend the day at the lake, with moderate to heavy trolling motor use, and when I return home and plug in the charger, all 4 banks go to “green” in less than 5 minutes. Thats either an exceptionally fast charger or a problem with the charger — I tend to suspect the latter. If I leave the charger plugged in all night, then unplug it the next day and then do a specific gravity check, the battery cells test around 1.225 (versus an expected fully charged specific gravity value between 1.275 and 1.300.). Wondering if anyone here has had similar observations/issues! C.
Just going green doesmt mean theyre charged, or finished charging,,,,just at a reduced amperage than while red. Give the good folks at AFT a shout and see what they think, but you may need a meter to check properly. Check the troubleshooting guide first, it may answer your questions, D. , || AFT INC., P.O.

Dbasketman -Thx for the link to the trouble-shooting guide – that does explain why the lights go “green” so quickly, HOWEVER it does not explain why the battery cell specific gravity readings are so low after an overnight charging. I do have a meter and am familiar with checking battery terminal voltages, but Ive always understood that specific gravity readings of battery cells is the best determinant of a batterys state of charge and this one appears to be coming up short, even after an overnight charging period. My previous boat, which had a Dual Pro Charger, would give battery specific battery readings after charging which were much closer to the 1.300 value which represents a fully charged cell. Also thanks for the AFT information — I may well have to make use of that.C.
I am having the same issue. I called AFT, he gave me some thing to check but agreed it didnt sound right. Please keep us posted on what you find out. (I also am a former owner of a DualPro never had any issues) T. Moss, 2007 Puma – Mercury 250 ProXS Chickasha, OK
The folks at AFT are super to deal with, and for the most part their products are as advertised, and warranty issues are handled with extreme speed and care. Good luck, D.
I talked with Rick at AFT this morning about this issue. He explained that since the batteries are new, they probably dont need for the charger to go into the “Bulk Charge” state (red LEDs), that the “float” state (green LEDs) is adequate to bring them up. He also said that as the batteries age and have more useage hours to expect the charger to have to spend a longer time in the “Bulk” (red) stage. When we discussed the specific gravity readings, he said that the specific gravity value representative of a full charge varies considerably from battery type to battery type and from manufacturer to manufacturer (first time I ever heard that) and the readings I have seen does not necessarily indicate an under-charged battery. He said that based on what I had told him that it sounded like the batteries were in good shape and the charger would reacting normally to their charging need. Based on what he said, I guess theres not an issue for me to be concerned with — guess I just need to get used to how this charger operates and not be influenced by how my previous chargers have performed. Posted as a FYI to anyone else that may have an interest. C.
Thanks, big help. I was having the same issue. Happy Thanksgiving!
Interesting comment on the specific gravity readings between different Battery manufactuers, I think I would be tempted to test that theroy by charging one of the batteries with a different charger to see it if made a difference to the battery, Then if not I wouldnt worry about the charger.
Have you taken any voltage readings before, after and during charging? This doesnt sound right.

After my fishing trip this past Monday, I did take voltage readings – 12.59 volts before hooking up the charger, 13 + (dont remember exact number) with charger plugged in and after it turned to “green”, 12.89 volts the next morning after disconnecting charger and letting it set for about an hour. These were the same on all 3 TM batteries. The batteries did seem just as strong at the end of the day as they did at the beginning. On the 24V system on my previous boat, there was always a distinct difference in thrust evident later in the day after moderate to heavy usage. I am still a little doubtful about those specific gravity comments I received, but at this point have opted to leave that alone, watch for a while and see what develops. The charger has a 3 year warranty, so theres some time to see what longer term results are. C.
