Battery equalization in southern California
I'm looking for a place or a person in southern California that can equalize my 2 Trojan t105s. I called a couple local battery shops and they didn't know what I was talking about. I know a few of you...

10 amp manual battery charger.
This is a c/20 charge rate for your pair of Golf Cart 2 batteries.
See how it says "Manual" ? Manual means that you become Manuel babysitting it while it does it's equalizing magic... in other words, you must be around to keep an eye on things, to measure the voltage at the terminals... you want it to get up to 16.0V, with the batteries disconnected from the trailer. Just disconnect the ground wire.
With a simple voltmeter to a 1/100th of a volt, bring the battery up to 15.7 to 16.0V. The batteries will be boiling, just a bit, so keep the lids on.
Unplug the manual charger when you get to 16.0V, immediately. It will be slow going with the meter to get the last 15/100ths of a volt to 16.0. This whole process, might, if charged up to 90%, take an hour, perhaps 2 at the most, of a little bit of checking every 10 minutes to see where the voltage is at, at the terminals. More frequent as the voltage gets a bit closer.
Let battery sit for a day. Take your hydrometer and read the specific gravity of every cell of each battery. Log the results. You should see 1.270 t 1.280 specific gravity for every cell. If you do, congratulations, your batteries are equalized.
regardless, the WFCO charge controller has to go... it wrecks very expensive batteries, all the time, playing it too safe with too low a voltage to do the job correctly.
To do it right, you must babysit the batteries, to a certain extent, after coming back from weekend trips, to really get them top charged off and back to 100% before storing away again.

This may seem complex, or difficult and confusing at first, but once you've done it a time or two, it becomes second nature... you know what to expect, you know how long it takes to do the batteries right, you know when to unplug.
If you leave a Pd9245 plugged in constantly , it does the big equalize cycle for you, once a day, for 15 minutes.
