UPG 85980/D5722 Sealed Lead Acid Battery (12V; 35 AH; UB12350)

This battery is my primary power source for a remote steel shed that contains all of my electric starting power tools and toys, five in all. The charge on all being maintained simultaneously by a 50 watt solar panel, a decent controller and this battery. I have no worries even after sitting for weeks in winter temps that all of my machines will start and that their batteries are maintained fresh. The primary battery also runs interior lighting, a CB radio, and my paging alarm system. This battery performs well at all temperatures, even well below zero. If I ever need to replace it, I'll happily buy another.

I have these and will be buying more. I have 30 of UB 12350 35 ah batteries that are almost 8 years old now. They run 2-1500 watt tru-sine inverters and are filled by 21 harbor freight 15 w panels, also 8 years old and 890 watt kyocera. With a 6+ year old HY energy HY400 12 volt wind turbine, known now as a Windmax HY400 5 blade. The Universal Battery brand is tough and easy to find. The Amorphous panels from H F are not the best but charge a hour before and hour after the Mono panels do and they do charge ( 1.39 amps) in a full moon!!! In full sun they still work well, 19 amps when they were new, 14.3 amps now after 8 years. New style HF (topray) panel seem better than the old ones I have.

Wanna save ? Use soft copper plumbing refrigeration tubing, type L to link your batteries. I have 3/8 OD inserted into 1/2 ID inserted into 7/8 OD soft copper pipe. Cut to length, bent to shape, hammered flat 2" of the ends and drilled 5/16 holes used stainless bolts and brass washers to bolt up. Slip 1 1/8" heater hose (black and red hose) over it to insulate "before" flattening ends cut 4 inches less than length you made. Handles 1500 amps easy, clean and saved me $400 bucks on cables for 30 batteries. Also made my 9'3" run to big 5000 watt HF inverter with it adding a 1/4" soft copper tube in the 3/8ths OD. I use it for 4 to 6 hrs a week of welding and cutting.

Suggestion? Shop Amazon suppliers for these. They will warranty them better than a local dealer, lesson learned on that one in my case.

****Helpful LEARNED facts: Never allow the voltage to drop to 10.7 volts, ever. That level is 80% D.O.D. (Depth of Discharge). When it drops to 11.4 you are at a safe but taxing 55% of D.O.D. and to make yours last as I have never let voltage get below 11.6 and you too may get 8 plus years out of your battery. I also hit mine with a 40 amp plug in battery charger 2 times a year till they get warm to stir them. I've owned Trojans, suretttes and Walmart (johnson controls) and NONE have the balls that 30 of these have (1050 hair frying amps) for my solar/wind home. Exide 6 voltreal good, Odyssey Deep cycle High $ but really good. The UB 35 amp So far, still kickin a$$. Your choice, I even have 6 of these grouped in 2 packs of 3 that for 4+ years have started my 1997 Ford diesel truck, cheaper than the batteries they told me I needed by $60.

I am shopping now for 30 more because I doubt they will make it through the winter in Idaho. But, I thought that last year too!

I have a Companion II Scooter it is about six years old and has been my passport to Freedom. When it died I had to call the VA (Dept of Veteran Affairs). About a month later I got a pair of batteries delivered and installed into my scooter. The batteries ended up being no good. Then I had to call the VA again. Two months later the VA authorized to have the key and accelerator assembly replaced. This didn't help as the problem was still the bad batteries. Then the on-board charger needed replacing. Still you can't charge bad batteries. The scooter has been down and unreliable since june 2011. By now it is time for me to take matters into my own hands, after all the entire scooter has just been rebuilt, and being an avid fan of Amazon I decided to buy a pair of batteries from ecom.Electronics after reading good reviews. They showed up lickity split, I installed them and my scooter is back on the road again. I have made two trips into town (about 3 miles round trip) for a total of six miles. I decided to charge these new batteries for the first time. Since then I have been to town three more times and the batteries according to my meter on the scooter is still in the green and going strong. So I am planning a fourth trip into town. These UPG D5722 Sealed Lead Acid Batteries are the best. I will definetly by-pass the VA next time and get my next pair of batteries from ecom.Electronics and avoid a seven month delay dealing with the VA. I highly recommend ecom.Electronics.

I now have 4 of these hooked up to my 12 volt off grid solar power system. I use 2 30 Watt solar panels to charge them and run low wattage LED light and small 12 volt fans and also use to keep my power tools charged. I have not been disappointed.
