UPDATE: I have purchased 4 of these batteries (4 years ago) and have a 400 watt solar array on the garage to charge them and use a 2000 watt inverter. I can run any tool in the garage (including a 2hp table saw) except an air compressor with a 2.5 hp motor. Last summer I took the 4 batteries and inverter to colorado camping in the mountains without any hookups at all. On a fairly hot day I ran the AC in my camper for 5 hours with only 2-100 watt panels to charge them and only dropped to 70%. Best test ever!! Running a microwave with just 2 of these works beautifully and hardly puts a dent into it for the few minutes at a time. My brother has a conversion van and does outings and only has 2 of these with a 2000 watt inverter and runs a microwave frequently instead of using a propane stove. For the price these are far better than most and can be set up inside due to sealed state without concerns. My only suggestion after reading other reviews is keep your wire lengths short and use heavy gauge cables. Best advice for any solar setup. also, if you run parallel, hook all equipment up to a negative terminal at one end of the bank and positive at the other end of the bank to equalize the charge and discharge. Just same advice for any solar setup. Great battery, good price. Arrived in fairly short order for such a heavy item. Had an issue with one that was dropped in shipping and leaking very slowly. Customer service had a replacement out in just a few days. The only thing I wish it has was wing nut terminals instead of bolt on, but that is only because I use them on a pop up camper and like to take them to the garage in between trips. I use 2 of these batteries with a 200 watt solar panel setup I bought so I can run a CPAP machine at night and never even put a dent in them with 1 nights use. I don't even bring the generator or charger as a backup any more as they get fully charged each day even with light use of a 600 watt inverter throughout the day.

I planned to use these batteries to power a small sump pump with an APS1250 inverter to prevent my basement from flooding but I've found I can also power other things as needed with them. (Winter 2019 Outage 1) No need for it to power the sump pump since it's so dry. I have two of these in parallel and I had a power outage over the winter of over 5 days. These two batteries in parallel hooked up to an APS1250 inverter/charger had no problems at all running my garage door opener, recharging my USB devices, or recharging my phone, or recharging my laptops during the entire 5 days with no power. There was also a day where the snow plow blocked off the end of my driveway and I couldn't get out to get to the office but had a meeting in an hour. Plugged in my home networking equipment (switch, fiber box, etc.) and was able to join the meeting from home. After 5 days the APS1250 indicated the state of charge of the batteries to be Red+Yellow which is 41-60% charge. The power came back on shortly after that and it took about 6 hours to charge these batteries back to full capacity with the 12V 30 amp charger in the APS1250. (Spring 2019) Lost power during 50+ MPH winds outside and a complete downpour with a river of water going down the street. The Tripp Lite APS1250 is powering just a small sump pump and and it pulls its power from 2 of these batteries in parallel. The Sump pump pulls in 1000 watts easily and it was turning on every 5 minutes and running for about 6 seconds. Power outage ended after an hour and through the entire power outage the APS1250 indicated battery capacity of the bank at 100% although it did click on the charger when the power came back on and ran for 30-60 minutes. Important Note: My APS1250 when configured for "AGM Batteries" keeps these batteries at 13.75 Volts when on line power. I see a number of comments by people talking about a 12 volt charge on these batteries and I think they are not charging these batteries properly. A 12 volt reading on this battery is the battery in a discharged state! Overall I'm satisfied with the performance of the batteries so far, I hope they last a long time.

Great Battery. Been using them close to 3 year on my wind Generators. I use them for back up of critical items like freezers, frig and sump pumps when the grid goes down due to weather or repairs.

I bought two of these batteries and hooked them together in parallel, and they seem to work fine with my solar charging system. I used them in the Arizona and New Mexico deserts from January through March last winter, and never had any problems with them. When I returned to civilization and stopped using them in the spring I had them disconnected for about two months and then decided I had better connect my regular plug-in type charger to them. It is one of those smart pulse chargers with the different charging algorithms, the Xtreme XC100. The charger had trouble charging them, first reporting "bad battery" and then, after a few tries, charging them from a low of 25%. It stayed at 25% for several days before I decided to put more charging current/voltage to them than the Xtreme could deliver. I zapped them with my old homemade charger for a day or so, and then hooked up the Xtreme again for maintenance charging. It was happy with the batteries then, and topped them off at 100%. I don't know if the batteries were not fully charged when I disconnected them in the spring for storage. If they were fully charged, they sure drained down quickly by themselves just sitting in storage. I should probably get a battery monitor for my solar charging system to keep track of the charging and discharging rates and depths, but my feeling is that these batteries are best when in constant use, and always charged fully every day. They don't seem to hold their charge for long periods of inactivity and storage. I could be wrong, since I didn't perform a suitable test to make sure.

Some reviewers made an issue of this not being a true deep cycle battery. While it is true that it states on the side of the battery, “Do not deep discharge”, one could take that with a grain of salt. This is not your top of the line deep cycle battery, but is still a much better value and much better built than any comparable flooded battery of the same size. I have beat this thing up far beyond what it would normally be used for. Have been running a fridge and deep freezer during daylight hours and sometimes a dishwasher to offset the electric bill. I have a small (2 panel) solar setup that keeps the battery from discharging completely, then charges back to full each morning before the next cycle. This thing has taken the abuse well and keeps working even after a year or more of this. These types of batteries last about 3 to 5 years even if you don’t use them much, so factor that in. Heavy use will decrease longevity, of course. Still a good value if you know what you can get away with. Would highly recommend for any purpose where the state of charge will not go below 50 percent most of the time. It will handle a deep discharge but would not recommend this on a daily bases.

I purchased this battery to pair with my MPPT 20A charge controller from Renogy. Like many of the dozen or so questions asking about setup, I had questions. This is an AGM SLA battery and Renogy does not have a specific setting for it in their menu options (THEIR SLA SETTING IS NOT FOR THIS BATTERY). Because of this, I decided to call the manufacture of this battery to understand how to safely charge and discharge this battery. Here is what I learned for those of you wondering about how to set this up in a solar configuration (some information applies to other situations). 100% charge for this battery sits at 13-13.1v. You need to let the battery 'rest' for 4-8 hours after charging or discharging to see where the battery is actually at. 70% 12.6v. 50% 12.3v. Batteries consist of chemical reactions not electrical nothing happens instantly. My solar application is in my SUV and the technical support person recommended I set my boost charge to 14.2v and my float charge to 13.4v. The float charge is slightly lower than the companies 'stock' float charge because the battery can get well over 100*F in the summer time inside of a car and it is important to be cautious to not ruin the battery (or worse cause a fire). The rest of the settings in the menu described by Renogy should be set to the GEL settings as AGM batteries are most similar to those. Lastly, as stated earlier, DO NOT set the renogy charger to SLA (or any other charger that is). The SLA setting has an equalization stage that this battery is not meant for. This is a stage where the battery is charged with a higher voltage than normal to off gas the battery (vent). This is not possible as this battery is sealed so please do not do this. Use the USER mode and use the recommended settings above. I highly recommend calling the company directly to ask questions as they can answer questions specific to your situation. ----- Battery specific review ----- The battery arrived without damage and after my experience above I believe they would be great to work with if something were wrong with my battery upon arrival. It is heavy so be careful when moving it. In my opinion, the terminals are a little- small? The bolt included mounts horizontal and so your connections will be horizontal to the batteries surface as well. There are washers included but I did not use them as I wanted my connections to be connected directly between the bolt and the prong (for lack of a better word). Having spoke with the manufacturer, I believe complaints about battery capacity are due to misunderstanding of the 20Hr rating. At a 5amp current draw over 20 hours, this battery (from a full charge) will reach 0. If you pull more than this- lets say 10amp- you'll halve your usage time. Keep in mind that you should only take this battery down to 50% depth of discharge (DOD) or 12.3v, so halve that usage time again. The only way to really know what you're pulling from your inverter (which is how you get power from any battery) is to get a watt meter and test your system. The manufacture of your appliance might state it is rated for 5amps @ 12v, but in actuality it pulls 8amps or more. Plan ahead and know what you intend to use this battery for and I am sure you will have a good experience. All in all I am extremely happy with my purchase and look forward to purchasing more batteries from them in the future.

I purchased 8 of these Universal Power Group solar deep cycle VRLA 100ah batteries for my solar application. We have been using Walmart marine batteries in our solar power system for the last 18 years. I bought these batteries to replace 4 year old Walmart Marine batteries we used with solar panels and a MPPT controller. I hoped to increase my stored capacity because the Amp Hour rating on these batteries was greater than the walmart marine batteries we had been using. Well after almost 4 months of frustrated use I can tell you that the Universal Power Group batteries do not measure up to the walmart marine batteries nor do they each store 100 AH of power. The 8 Universal power batteries will not charge past 12.5 volts (marine batteries charged to 13.4) and do not provide power near as long as we saw from the Walmart marine batteries which cost less $$. After reading other reviews I think we probably have some bad batteries in the batch which are dragging the other down so I'll have to load test each one next time I'm at our ranch. FOLLOW UP I load tested each and every battery after charging them to 12.1 - 12.3 VDC and they all tested good. The problem with these batteries is that the MPPT shows them at 13.1-13.4 vdc as long as the sun is at peak elevation in the sky. As soon as the solar panels are disconnected the battery voltage drops to 12.2 - 12.4. This means the batteries aren't charging past 12.3 or there abouts So not way they can output 100AH. They have done this since new. They are now 3 years old and discharge much faster than the first year. I've even pre charged the batteries (using a 75 amp smart charger) to 12.3 volts prior to the sun rising and then let the 19 watt solar panels charge the batteries all day long and once the sun goes down or if the panels are disconnected the battery voltage almost immediately drops to 12.2-12.3vdc.

Used in Sailboat with 200w solar charging. WORKING GREAT! So I bought three of these to install in my 88' Hunter 30' sailboat. I hang on a hook A LOT and needed power. The boat originally had a pair of Group 27 Batts and was wired as 1 house and 1 starter. I installed 2 in the OEM location and ran 10g wire to a third under the port side lazzeratte (bank 2 - house). I have 2 - 100w flexible panels laying on the bimini (tied to it though), wired down to a 20a PWM charge controller. The boom slightly shades the second panel half of the day at dock and unless I move the traveler all the time at anchor (damn winds). Replaced all the lights with LED, the 15" TV is LED and the Stereo is a 20w Digital style sold here on Amazon powering (2) 6x9 speakers. Charging both iPads and phones... Basically it's abused lightly. But on occasion, say 3 times now, I'll turn on the 1000w pure sine inverter and run a window A/C 5000btu unit in the companionway off these for about an hour (the Chesapeake Bay gets darn hot) near sunset to cool the cabin down to 70* (forget running it on battery power during the day - you need 2 hours to cool it - shore power works better). So with Batt1 wired for Starter and the other two for house but at anchor I'll run both banks together and when I leave her for the week so the batterys stay balanced and charged (Solar charger only wired to Bank 2). I have no issues starting the 2GM20F engine and no issues with the batteries running my weekend and sometimes 4 day journeys. I have a match and these batteries out of the box have been great. The reason I wanted these is my experience with the manufacture and the sealed aspect when charging while I was away on a solar controller. Also since sailboats tend to lean (heel) the water doesn't leak and I don't cause any issues with shorting cells. AGM/GEL on a boat or don't bother. You don't want the hydrogen gas in the cabin (bad for you, and really bad for corrosion) and you don't want battery acid eating your bilge pump impeller.
