Someone said now JC batteries were not being made in the USA.


I have not seen any.. They are made in spain and brazil most AGMs say Germany. I have seen some say Saudi Arabia.
I saw a 51R2 AGM that said made in KOREA on it.

It didn't even say S. Korea... could be North Korea for all we know.

Our CR-V employs the "logic" WRCsixeight mentioned above. Every few months I try to stick a computerized charger on it to top it off. I ran it this weekend. It amassed around 5 amp-hours into the group 35 battery, which is probably about 10% of its capacity.

I did the same thing with our F150 running a larger H8. It has start-stop, and based on the current shunt on the batter terminal, probably also uses similar logic. 7 amp-hours into it, which is again roughly about 10% of its capacity.

granted, it won't be a true 10%, especially if some of that energy is going into desulfation and waste heat.

charger was set with a 14.4v cutoff and 6 amps; it reaches 14.4 then reduces current to hold it there until it reaches under 10% of the current setting, then taps out.
