Description

Sealed Battery&Safe Charging 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. Specifications: 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 Our batteries can be used in various types of: Connecting batteries: NOTE: The maximum number that can be connected in parallel is 4. In series, there are no limitations. IN SERIES 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. PARALLEL 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. IMPORTANT INFORMATION BEFORE YOU BUY 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.

  • Great battery
Style: 100Ah Deep Cycle AGM Battery
I’ve only had the battery for about a month but it’s seams great so far, I use it for garage audio, I keep it on a 1 amp charger all the time it powers a 5000.5 amp, head unit, and cooling fans haven’t seen anything below 12 volts full tilt so far

  • Good Battery So Far
Style: 100Ah Deep Cycle AGM Battery
Great battery so far. It’s being used as an external battery for a ventilator while out and about and for emergency power for the patient. He can’t initiate breaths on his own so it’s essential for him to have power for the ventilator. The medical supply company only gives you a small 35ah battery that only last about 8-9 hours. If you want an optional bigger higher AH battery you have to purchase it on your own. This battery should last a full 24 hours before it needs a recharge that’s plenty of power for going out in the community and in the event we have a power outage and need backup power. It came well packaged and about 65% charged. The battery took a charge well and held its voltage after. I bought a group 29-31 battery box but I think I could’ve gotten away with a group 27 battery box however I’m not certain of that. We haven’t used it a ton yet but so far so good I ran the ventilator on the battery for over an hour and no issues and the battery provides stable voltage. I’ll update further if I have a reason to. ... show more

  • Good batteries
Style: 100Ah Deep Cycle AGM Battery
This is my 4th order of Weize SLA batteries. They have performed well. I just removed my 1st set from primary service. They are 5 years old and for the last 2 years this set was abused and lasted. I ran these batteries to near 0 multiple times a day every day for almost 2 years while constructing a cabin. The only issue is 1 terminal started corroding after a year or so but kept working. ... show more

  • Great batteries for your buck
Style: 100Ah Deep Cycle AGM Battery
I bought these batteries for our motorhome. I actually should’ve bought these in a 6 volt configuration, but I didn’t. I can report that these batteries are still going strong after about a year and a half. They came packaged extremely well. These batteries are heavy, but that is to be expected. This company was running a deal when I bought them. I bought five batteries for what amounted to be about $160 after shipping. Great price alternative to some of the other bigger names in the industry. I would buy them again. ... show more

  • Good Battery, Fair Price, Great Customer Service
Style: 100Ah Deep Cycle AGM Battery
I ordered this battery for my small RV. The unit arrived well packaged and in good condition. Be aware it's a lead acid battery, so its heavy! I had the battery connected to the RV since January 2025. It performed as expected without any issues until September. It suddenly began to discharge itself and lost capacity. I contacted the vendor, Arkpower, and they responded immediately. They had me perform some diagnostic tests to try and figure out the issue. The battery likely had a cell failure. Arkpower was very helpful and responsive. They ended up sending me a replacement battery. I will definitely purchase from this company again. ... show more

  • Would never buy this brand again Would never buy this brand again
Style: 100Ah Deep Cycle AGM Battery
You get these inexpensive because they are not made up to par. I got this battery in April of this year and by the end of May it is no good. My system completely failed on me. So I put this battery on a trickle charge on my very reliable battery charger and it would not charge past 12 point to six. The resting voltage for this battery is supposed to be 13.5-13.8. but the charging voltage is 12.27. so every piece of literature I have read says it's a bad battery. Whether it has calcified inside, whether it has a bad sale, or whatever is wrong with it, it's a bad battery regardless. Now the warranty comes up and they are refusing to give me my warranty. So please be aware of what you're buying because not everyone is honest. And some will do their best to cheat you. ... show more

  • These are actually really good Lead Acid batteries. These are actually really good Lead Acid batteries.
Style: 100Ah Deep Cycle AGM Battery
(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. ... show more
