Free sealed lead acid batteries

There are 3 packs, each contain 8 of 12 V (5VA?) sealed lead acid batteries. I am told they are new, from an expensive ups that turned out to be dead.

Please just take what you need. Left them in the 3 week area.

PLEASE TAKE CARE WITH THE LARGE PACKS, you have over 100VDC on that connector with a bunch of chemicals behind it to make sure there is a lot of current flowing. There is a protection device on one of the chained leads, not sure when it kicks in though.

I’d like to pickup 1 of the 3 sleds this weekend if any are still left. Want
to tie it together with my solar panels.

I see VHS is closed, anyone going to be onsite during the day today opening the space as I’d like to come and pick up one of the sleds today as I’ll passing through the area several times.

@Jarrett says he will be coming around 6pm. (Making really cool graphs with InfluxDB and Grafana - Tonight!)

I may take one row. I have some camping plans…

Thanks Shane, I’ll try and swing by after 6pm today, but that’s a low
probability, it’s more likely I’ll come to the space over the weekend,
probably on the way to/from the farmers market if the space is open.

Anyone know how much these sleds weight, do I need to bring my heavy duty
cart and a hydraulic lift or easily sling under my arm?

I’m thinking about UPSes in general where the larger ones easily weight
100lbs+ most of which is the battery weight.

They’re pretty heavy, but Tom just carried them in one at a time, so you should be fine doing the same. Unless you have a back injury - then don’t risk it. :slight_smile: We do have a small rolling cart at the space that can be used to wheel them to your car if necessary.

I took one of the packs. It’s about 40 pounds. Definitively at the point where you may want to consider a second set of hands.

Thanks guys I’ll bring my cart when I come over to pick it up in about 30 minutes.

Anyone have success charging these, I tried hooking up an automated car charger last night, the error light was flashing. I’ll read up some more, perhaps a current limited p/s is enough?

These are the ones from the UPS you put into the 3 week bin?

I haven’t had a chance to do any testing with them myself. Though I’ve
painfully stubbed my toe on the sharp edge of the case a number of times!

This actually reminds me of a question I was meaning to post before…

I am wondering what model UPS these came out of, that’ll make it easier to
figure out the correct charging regime for the sled as a whole or the
batteries individually.

I started to take the sled apart to check the specs on the individual
batteries but got distracted and haven’t gotten back to it.

My first guess would be a 48v input source, but don’t know either way.
