Deep Cycle AGM SLA VRLA Battery

The 12 Volt 100 AMP Hour Deep Cycle Battery uses a state of the art, heavy-duty, calcium-alloy grid that provides exceptional performance and service life in both float and cyclic applications.

SLA batteries have a low self-discharge rate – about 40% per year or 3.3% per month. These batteries are able to be stored without charging for up to 5-6 months when at full capacity, but doing so is not recommended. At least every 2-3 months you should top charge them. In order to prolong their shelf life, SLA batteries should be stored and maintained properly.

Best Practices


  • Store batteries in a cool, dry place (optimally 75 degrees Fahrenheit / 23 degrees Celsius or less)
  • Periodical top charging of the batteries is recommended
  • Store batteries in a fully charged state


Our batteries can be used in various types of:


  • Access Control Systems
  • Home Alarm Systems
  • Burglar Alarm Systems
  • Security Systems
  • Electric scooters and bikes
  • Electric wheelchairs
  • Ride-on Toys
  • Golf Carts


Connecting batteries

NOTE: The maximum number that can be connected in series is 4. In parallel, there are no limitations.


By connecting the batteries in series you are doubling the voltage and maintaining the same capacity (amp hours). Connect the positive terminal of the first battery to the negative terminal of the second one. From the two free terminals connect the positive to the power lead on your devise, and the negative to the ground connection of your application.


By connecting the batteries in parallel you are doubling the capacity (amp hours) and maintaining the same voltage. Connect the positive terminal of the second battery to the positive terminal of the first battery. Do the same with the negative terminals. Connect your application to the positive and negative terminals of the first battery.


In order to find the best replacement for your original battery you need to compare the physical dimensions, Volts and Amp power of your original model to our battery. Besides physical dimensions you also need to check battery terminals , which are the metal connectors on top of the battery. To determine what terminal your battery has, you will need to look at their form and determine if they have a flat connector, nut and bolt or wires, and then measure their sizes.

  1. K. J. Lars

    UPDATED 2 MAY 2021: As I mentioned in my original post we boondock 90+% of the time. Since my original post I purchased two more of these batteries. I now have three of these batteries installed in parallel in our travel trailer. I installed three REC 330 watt solar panels along with a Victron Charge Controller and 2000 watt AIMs inverter. Additionally, I installed a MicroAir Soft Start in the Dometic 13500 BTU A/C system. All items except the solar panels were purchased on Amazon; Amazon does not have a seller for the panels. I am providing this system background so you understand the following experience with these batteries.Now for the results of multiple boondocking trips: These batteries provide all the power I need in the trailer. I can run the microwave, refrigerator and even the A/C. I use a CPAP at night on 120 Vac. These batteries get a real workout everyday. I have run these batteries down to 30% charge (about 8 Vdc) and they come back every time to full charge with a few hours of sunshine. Yes, the solar power does add power for the daily usage; the charge controller uses any excess power to assist in running the appliances in the trailer when it is not needed to charge the batteries. So, far these batteries have proved themselves to be reliable under heavy usage and take a beating without failure.I highly recommend these batteries.Original Post:I bought this battery for use in a travel trailer when we are boondocking (dry camping with no power) to provide a limited amount of 120 VAC power via the inverter. The trailer came with a single type 24 battery. This battery is described as a type 24; However, it is much larger than a typical type 24 battery and would not fit in a type 24 battery box. So, I returned the battery box and purchased a larger dual battery box that would hold the current type 24 battery and this one. If I was attempting to use two of this battery a very large battery box would be needed. The battery does what it is supposed to do. Have not yet used it for dry camping which is what it was bought for, will update after our first trip.

    This item came directly from the retailer,, and much faster than my regular Amazon deliveries. This is a very dense (small but heavy as it contains a lot of lead) and it was packed very appropriately and compact so to minimize any damage. It came to me at 12.8V, and was dated so I knew it was freshly manufactured. It’s price was somewhat less than its branded competitors (and substantially less than I could get a similarly rated AGM battery locally), so I was a little leery. However when it arrived I could see it was as well built as any others. The sizes provided in the ad matched the actual item exactly, so it fit where I had planned it. Overall, I am very happy with it (small RV solar charging system component).

  3. Amazon Customer

    I had this battery over two months and use it for the projects in the shed. It has been brought down to 11.volt and next afternoon I am back at 13.3 so the battery cycles good so far will judge it 4 months down the road.

  4. Cosmos Joseph

    I expected a little more protective packaging but it arrive without a scratch. Now I’m using this battery to power my solar powered internet radio and recording studio. I got 300 watts of solar power with a 20 amp charge controller charging it during the day. A 600 watts pure sine wave inverter gives me the 110 volts I need day and night. When the sun goes down and the battery is fully charge it keeps my equipment on all night long until sunrise the next day. It came with nuts, bolts, washers, and lock washers for both poles. It also came with protective caps for the poles (see photos). I need a total of 400 AH to power all my equipment so I’m definitely ordering 3 more.

  5. Mr.H

    I use these batteries on my solar system. Using two now. Plenty of power. Running one 1500 and one 500 watt invertor. No problems. Will be ordering more to add greater storage capacity.

    (SEPT-2021)Well, after a full year of daily use, and an additional battery added to my bank, I’ve upgraded my review to 5 stars for a number of reasons. I added a 3rd battery in parallel to my bank about 4 months after the first two were installed, bringing the total to 300Ah/3.6KWh (or 150Ah/1.8KWh @ 50% DoD). We have since added a small wind turbine (200W) and an additional hybrid wind/solar charge controller. During the day I have our 2 portable solar panels (100W and 80W) feeding the 2nd charge controller. Throughout this hot and humid summer our off-grid system has ALSO powered numerous box/window fans, etc and has performed rather respectably, considering they were under load roughly 18+ hours a day. I will DEFINITELY be upgrading to LiFePO4 batteries for our new home’s system, but I have found that for their price and performance, these Weize 100Ah batteries are clearly some of the best you can get, especially from Amazon.———————————–(FEB-2021)Writing this review after 6 months of daily use with these batteries in an off-grid solar powered system. I’m using two of these batteries (in parallel) as the bank for my system. I have a Epever Tracer 3210AN 30Amp charge controller and four 100W HQST panels charging the system, and a 1200W Giandel Pure Sine Wave Inverter providing the 110V AC outputs. The 2 main uses for the system are to run three LED full spectrum grow lights (for 14 hours a day), and to provide charging facilities for our two Rad Runner electric mopeds (672Wh battery packs each). On top of that, I have a habit of also using the system to recharge our power banks, phones, tablets, etc. So far, so good, as there is never really a heavy load on the system (~250W if BOTH bikes are charging), but after reading more about these batteries, and Sealed Lead Acid batteries in general, I DO wish I would have saved a little more and just got a 100Ah LiFePO4 pack, or built one myself. The 80% vs 50% discharge depth and the THOUSANDS of charge cycles they are rated for actually make the total ownership cost of the Lithium batteries a lot cheaper (per KWh). Also, the packaging for these batteries is atrocious. Literally came in a single-walled cardboard box, with a styrofoam insert underneath the battery, and another on top of it. BOTH of the inserts were broken into multiple pieces and it looked like the box had been tossed down a set of steps, but alas, they appear to be working fine.

    Six in total were ordered and received. These will be storage for six solar collector panels. Why you ask? Instead of a gas generator, that creates noise, carbon monoxide and air polution, toting gasoline, etc., an alternative energy source to me was the better choice. With the solar panels to collect energy, batteries to store the energy and an inverter to convert the energy seems like a safer way to go. The system built will be enough to run a portable AC unit when it is sunny outside, the fridgerator and a fan should we lose total power from no electrical service. Cloudy days, well plans on getting a wind generator are in the future. Off the grid, why not!

  8. Paul Thomas

    Works like a charm. Have it hooked to my Newport 55lb thrust troling motor as seen in the pictures. That first day we where on the lake for 6 hours motoring around. According to motor specs I am able to run at full speed for 2 hours with this battery. After 6 hours of tooling around at various speeds we where only down to half charge, very impressed.

  9. David Figgat

    I use a cpap machine. I have only used this a couple of times camping and so far have been able to use this battery both time and after coming home had a lot of charge left. It charges easily and seems durable. I have tried a lot of other products that just couldn’t hold enough charge long enough for tent camping without charging in between. It is nice to have something that is dependable.

  10. Bruce B. .

    I bought two of these batteries to put in my RV and also added solar panels. I have had no problems with being able to carry the load over night until the solar panels can recharge them. I will be getting more of them when i install an inverter to the RV
