I have a good sized stock of Valence U-Charge RT Series U1-12 RT, one 24RT, Some large capacity Gel Cells. Also a number of Tripp Lite chargers / Inverters 300w, some multi chemistry smart chargers. I live on the Florida Space Coast. All in excellent shape and full capacity. Pulled from high priority working stand by equipment. Let me know if you see anything interesting.

Price on the U1-12RT? What do you mean by full capacity? How did you test them? I may be interested in two depending on price and condition.
 
The Batteries were pulled from equipment that was basically stand by. I have used a number of them in projects such my homemade segway and to replacing the led acid in a friends wheelchair. The things seem to never run down. WAY more power at WAY less weight. How should I test them? I really haven't given it much thought.
$200.00 seems to be the going rate and these seem to be in really good shape. Never any high demand placed on them. I have 10 of the black ones that I believe are older models. I could do $150.00 on the black ones or a discount on quantity.
I'll sell you the three green ones in the picture for the price of 2 ($400.00 & shipping) and if they are not up to your standards, you ship them back and I will refund your money. That is with in 10 days of receiving, this is not a warranty thing but an acceptance thing. That offer is good till 7/6/2020 midnight. East coast time. After that Ill probably have them on Ebay, no discount. No return. Thought that I would give you guys a shot at them first.

I just got 3 more of the Valence 12v 40Ah U1-12RT in and they are in great condition.

I know I have not been able to run one down and my neighbor keeps going and going and going in her wheelchair that I retrofitted with the black ones a little over a year ago. She says she is getting almost double what she was getting on her heaver, bigger 23Ah Jellcells. Which is about right 23Ah as opposed to 40Ah.

I’ll know Tuesday what the true capacity is on these guys. I have a Battery Coulometer arriving. That is by the suggestion of SDUser.

I sold SDUser two at a ridiculously low price but I need to get this hole PayPal and UPS shipping figured out. His batteries will arrive on Tuesday as well and I’ll see if I can get him to comment / rate the things.

I also have 10 of the older black versions that I would like to sell. Make me an offer on the lot?

Newer Green version - $225.00 including shipping in the states.

Older Black version - $ 175.00 including shipping in the states.

100% satisfaction guarantee on acceptability full refund. Buyer pays return shipping.

Now that I have this all worked out Ill be putting them on eBay so if you want them. Get them now.

They will be higher on eBay and the shipping will be double.

Yes, they are U-Charge. The internal BMS will take care of the rest.
Valence is one of the most reliable batteries on the market. That is why they are chosen to be used in the equipment I remove them from.
These come from machines that are part of an Open Heart surgical sweet. They sit as standby power that is never activated, so these are like brand new and are tested to verify that they are within 90% or the original capacity.
This is an older thread and I have been forced to raise the shipping. But for you, I will honor this price.

I hope you don't mind my post. I am not in the market for these as I already have 2 of them. I wanted to back up everything you have posted regarding these batteries. I have had my batteries for a year and they are great. Bought them off ebay.

I will also add your price is very reasonable since you have tested them and are offering returns. These batteries are actually LiFeMgPO4 batteries making them very unique. The main advantage of adding magnesium is it provides for a longer life cycle and might explain why these batteries age so well. (y)
 
I bought a couple of these batteries from Joe Regular and it was a successful transaction. Good guy. If I needed more I would not hesitate to buy again.
 
Thanks Gazoo, one of my favorite characters growing up, and you know your batteries too.
sduser, good to hear from you again. Thanks for the endorsement as well. I try to treat my customers as friends. So thank you.
 
OK guys, I have been on unemployment for a while now, and the money is starting to get tight. If your interested in my last three. PM me and make me an offer.

I have three of the older black versions. One at 35Ah and 2 @ 33Ah. The green ones were running at 36 to 39Ah.
$160 each including shipping. The photo shows 4 but I already sold one.
