only working at 12%. UPG batteries are cheap for a reason and if you buy them, you risk your wheelchair (or your child's or elderly parent's wheelchair) being stranded in a place where help may not be available. Is that a risk you want to take? Is your safety or your family's worth the discount? I suggest you dish out a little bit more and get Duracell's or another quality brand batteries that won't leave you in a bad situation.
I thought all was well, second set. Batteries started failing at 7 months, and you guessed it they would not honor the1 year warranty, claiming it goes back to original date of purchaes, not installation or manufacture date. Amazon finally did the right thing, but was warned they have a rotate vendor selling junk as medical batteries!
I initially purchased these batteries because they are sealed lead acid, AGM. Absorbtive Glass Mat technology is proven to be reliable and very efficient and was exactly what I was looking for. I am currently using these with a small solar array at my house. Although I'm an electrical engineer with 20+ yrs of experience, I wanted to start small to better understand the technology and techniques before scaling up to a more major install.
I've learned a tremendous amount and am ready to begin a major upgrade. During this time I can say that my (small) "bank" of batteries has performed extremely well. I have not connected any of them to a CBA (computerized battery analyzer), but they have been cycled numerous times as I've powered a couple of rooms in my house with them. There have been no problems whatsoever. I am very pleased.
Now that I am looking to upgrade, I've been comparing batteries, battery companies, etc. I have found that these little AGM batteries have very similar characteristics to the better known solar battery companies (like Trojan, Concorde, etc.). So, after deciding the performances were comparable, I wanted to know what the difference in price will buy me. Here was part of my analysis - and I hope it helps anyone who is looking to do the same:
Volts: Nominal voltage of the battery
Ah: Amp*Hours (theoretically how many AMPS you could pull for one hour before full discharge ++)
Wh: Watt*Hours = Volts x Amp*Hours (Theoretically how much POWER a battery can produce until full discharge ++)
++ This number will change as the discharge rate changes. The slower the discharge the longer the life of the battery.

And for the UB12350?

The cost per Watt*hour for these batteries is by far the lowest for the AGM batteries I've listed above.
This analysis seems solid to me. To boot, these batteries weigh about 22 lbs each - rather than 60 to 100 lbs for other "solar" batteries like the ones listed above. The downside is that I will have to make many more connections between batteries, but I'm willing to do that rather than pay 30% more for the SunExtender series from Concorde.
If anyone - after looking at the datasheet for this battery compared to the Concorde series - can see a reason why I would choose NOT to use these batteries for a larger solar system, PLEASE leave any comments.
