US Batteries...6 volt..Good to use?

 
I've just purchased some 225 AH 6 volt model 2200 US Battery batteries
for use with  160 watts worth of solar panels. Made in Georgia (USA)
Anyone have experience with these batteries?

I'm curious to see how good (or bad) they are. If they are OK. I'll be
adding a few more of them to the battery bank in a week or so.

Seen some of these in a system. Would not be my first choice but the
owner got around 5 years out of them. He was not much when it came to
maint.

How many you got? That will determine whether your panels will feed them.

Six at this time. I'm just connecting them together for 3 groups of 2 at
twelve volts total. I've got an antique voltmeter (1 ma movement) so I
can monitor the voltage faithfully. It will be continuously connected.

The T105 Trojans seem almost identical electrically, weigh a few pounds
less and cost more. The cases, though a different colour, had the same
carrier hooks...very suspicious..

I've got a fifty amp charger for any major charging needs, but I hope
the sun can at least feed the four hours of night lighting (150W) and
self discharge needs.

These things weigh 63 pounds each, according to the specs. I was really
tempted to go with two volt cells, but anything decent was way over what
I wanted to spend.

If I get more batteries to reduce depth of discharge to never more than
say, fifty percent AND watch the acid level faithfully, do you see any
problems in getting a long life?

Three parallel strings and you are dipping into the area that is best
avoided.

If you mean 550 Wh/night then you will use less than 8% of you batteries
capacity.

 

Make that 600Wh and you are still under 8% discharge.
