When I'm plugged into shore power, my house batteries always show around 13.6 However when I unplug, they will drop to 12 with nothing on and then go down to about 11.6 with very little use.
The batteries are around 2 years old. The fluid level is Ok. This is a constant. New battery time? They show good on a load test.

What kind of batteries do you have -- 6V Golf Cart or 12V Deep Cycle? How long do you keep the charger on? If your batteries are that low they may need a day of full charge, rest for a day and then charge again. If you have a 3 stage charger than you could eventually get it to go into an equalization period. If your batteries drop off quickly below 12 volts then you may have a shorted cell. Take a measurement after they have rested for an hour and again after a day. Let us know what you read.

Hello Finhawk,

If the batteries test good under a śload test' then there is likely a loose connection (*) somewhere in the circuit. With a good digital voltmeter, test the battery bank right at the battery terminals. If that shows around 12.8 with a slight load than a connection would be suspected. The only good way to find it is to check the voltage drop across each connection and that would be tough to do. Unless you feel up to it, this might be a job for an electronics tech. or an electrician.

13.6 when charging is okay but if the battery reads the same 12 to 11.6 volts at the battery then its new battery time even if they do test good under load. Have the tester do a 20 Hour - Amp./Hour test if they know how and compare the reading to the published rating for the batteries. If it's less than 80%, technically they are at their service limit. Although I wouldn't toss them out till they were at 75% to 70%.

(*) loose connection in this sense means one that is not tight and has a few mille ohms of resistance

These are 12 volt deep cycle I've run them dead- dead a couple of times. the electrolyte level was at the top of the plates on some cells before I added water. But they've charged for 2 weeks since then. Still doing the same thing. And it seems to be an immediate drop.
I'm not sure of the age. I may just go to Batteries Plus and restock
