What can I expect to get for my old inverter batteries (16 Trojan T-105, red)?

DonP - the going rate for old invertor batteries is about RD$700 each. Have you tested each one with a Battery Load Tester? Some will still be good!!

DonP -This is a battery load Tester. If they show good then you get more money for them and they sell in Compraventas here for up to RD$3000 so figure 50% of that.

I bought them in Sept. 2010 and we are still using them, but now they seem to loose their capacityrather quickly.

I do not have a load tester; they are too old to doctor around with them anyway... ;)
The new ones will arrive today, so we'll have them on stand-by and ready to swap.

My wife inquired in LT; they pay 625 RD$/each. that's OK.

DonP -You got a reasonable life out of them - nearly five years. That is what most people report if you look back through the threads on Batteries and Invertors.

Don't scare me Olly....

Jan 2009 and still going strong but they're deep cycle gels..... 36 in the string

I think the bigger the bank, the less stress they get, the longer the life..
Just my thinking

Fingers crossed

WW - the Gels should last about 10 years based on all reports I have seen and with your Solar set up they will not be stressed so much on charging. They will be cycled every day though!

Bigger banks are harder to "balance" and hook up correctly. If a larger set of batteries goes out of balance, one chain can stress the others and cause rapid failure.
Articles I have read advise against more than two chains of batteries, but people like yourself and DonP have had good luck with them.

For larger capacity systems it is better to get high capacity 2 volt per battery (single) cells in a single chain. I do not know anyone who has done that because of the cost of such batteries.

Last year we got 1000 pesos each for T105s. This year our inverter guy said the price had dropped, and he was right, we only got 700 for them. [Two different inverters]

Thanks boys,

3 banks of 12 is my set-up..... 2 inverters.

Using my % meter, they go down into the high 80% range every night and kick up by noon the next day.
I watch it like a hawk.

10 yrs seems to be what I remember from the installation

When you have a large # of batteries to sell at the same time you can get more money.
Hold out for 800 pesos!!!!!!

DonP - make sure you get Trojan Reds that have the Guarentee certificate stuck to the sides. This tells you they are genuene ones!

Us245xc

This time we bought US245XC from the importer in SD.
Fresh batteries from the same pallet, all checked with a voltmeter.

Scrap Price for lead acid inverter battery such as the Trojan T105's is RD$900.00 - RD$1,000.00 each
at a collection center (metalero), depending where, where are you?

The guys picking up in the street will be RD$700.00 - RD$800.00 each.

With as many as you got, you should be able to get top price, at a collection center maybe even a little more...........

g'luck

We are in Saman? (on the S?nchez - Las Terrenas road).
If it is not too far we can deliver them with our pick-up.
