Best RV Batteries of 2025

"I use this battery while camping, and I've been pleased with its performance. It's heavy, but I chose it for safety reasons after hearing horror stories about lighter batteries. Great charge retention and it works well with my solar panel."

"I inherited a Goal Zero Yeti 1250 with a dead battery and found that this Renogy replacement was a bit tight, but it fit. Charged up quickly, and I'm looking forward to testing its performance this weekend."

"I initially bought this battery for camping in the Texas heat, and it started at 80% charge. However, I noticed it dropping to 63% while using it. After contacting Renogy, I struggled with their customer service, which was less than helpful."

"I recently installed this 12v 100Ah battery as a replacement for my backup sump system. It fits well in the Wayne battery box and is operational again. I appreciate the webbing handle; it's accessible and easy to carry. Yes, it’s a bit heavy, but that’s expected with a lead acid battery."

"The battery arrived securely packaged, which was important given its heavy weight. I paired it with an inverter for a 1/2 hp sump pump during power outages. After testing for twelve hours, the battery held up to 80% charge, which exceeded my expectations. Overall, it seems like a solid product."

"I experienced great performance with the three batteries I bought for my solar generator. They provided much more capacity, but after about a year, they started losing charge efficiency. I reached out to Weize for support, and their customer service was outstanding. They responded promptly and offered either a refund or replacement, which I appreciated immensely!"

"I replaced two 6-volt lead acid batteries with four of these batteries to power my 12-volt system in the trailer. They last about 6 days before turning off. The customer service is excellent, responding within 1-2 days. However, I found that their wiring diagram was a bit misleading. I wired them to busbars only, which worked perfectly!"

"I've been using these batteries in my boats for air conditioning and amps. One battery failed last year, likely due to a bilge pump issue, but overall, I’ve had them for over 3 years without problems. The weight savings and runtime are impressive, and if they last 4-5 years, I’ll be very satisfied!"

"I received my battery earlier than expected, which was great. I replaced my lead acid battery, and when the power went out for about 5 hours, the new battery kept my fridge cold and lights running without dropping below 13.2 volts."

"After 4 months of use, I have no complaints. I confidently ordered a second battery during a Black Friday deal. They work great in our travel trailer, and I highly recommend them."

"I purchased two 12V 100Ah batteries with Bluetooth for my trailer. They arrived well packaged and included everything I needed. However, I faced issues when only one battery was discharging. I had to monitor them through the app, which was frustrating during my camping trip."

"This battery works great and lasted a long time powering my small travel trailer. I was amazed at how long the charge lasted, how lightweight it is, and the cost was reasonable considering the size and amp hours of the battery. The app and Bluetooth connection work well and are a must-have. I highly recommend it."

"This battery is next level. The controls and information the app provides are incredible! It gave me real-time temperature as it charged, along with the time to complete charge."

"It works just like they said it would."

"I bought two of the 100 amp hour AGM batteries about two years ago for my off-grid RV. They’ve worked flawlessly, powering everything I need, including a 700-watt pure sine wave inverter. I just purchased two more for my main RV, and I’m really happy with the brand and quality!"

"I have two Zohler sump pumps, and I wanted a backup system. I connected the battery to a 1500 Watts UPS inverter. During a heavy rain, it powered the second pump for two days, using about 50% of the charge. I think it's a solid battery, especially for a secondary system!"

"I purchased four of these to replace lead-acid batteries in my motorhome. The constant use of the old batteries was cooking them, and I hope these AGMs will last longer. They seem cleaner and more durable compared to flooded deep cycle batteries."

"I appreciate how Optima batteries deliver amazing power and run time. After trying economy options, I realized that going with a recognized industry leader was worth it. Just remember to use a charger specifically for AGM batteries to avoid damage. I recommend these batteries for any marine use!"

"I purchased an Optima battery just over a year ago. Initially, it barely cranked my outboard motor, and now, after charging it multiple times, it's still weak. Disappointed, I reached out to customer service, and they are honoring the warranty, which is reassuring. I'll update if I receive the replacement."

"I have been using Optima batteries for years and have had good experiences until now. The last two batteries I ordered arrived damaged due to poor packaging. While Amazon's customer service was helpful in addressing the situation, I ultimately chose to get a refund instead of another replacement."

"I purchased these batteries to replace the old ones in my camper since they weren't holding a charge. They have been performing exceptionally well, and I'm really impressed. I would definitely buy again!"

"I absolutely love these batteries! They last longer and provide more amperage to my inverter compared to lead acid. I never knew about the C rating until last week! We're planning to add more batteries for emergencies."

"So far, these batteries are working well for my solar setup. I can't confirm the capacity yet, but they seem reliable. Customer service has been very prompt and helpful."

"I purchased three batteries, and although one failed after 6 months, the seller quickly honored the warranty. I sent the faulty battery back, and they sent me a new one. I’m impressed with how long they last while we're out on the water, and I'm glad I saved a box for the return."

"I bought four batteries for my RV and was amazed by their recharging abilities compared to my old batteries. They’re lightweight and easy to store during winter. Even though they lack freezing protection, we rarely camp in winter, so it's not an issue for me."

"I ended up getting four of these batteries to create a 200 Ah battery bank. They fit perfectly on my shelf and are well protected from the elements. I even picked up two more during a sale for a separate 12-volt bank."

"I'm thrilled with this battery! It's incredibly lightweight compared to lead-acid alternatives. I've set it up as a portable power station with an inverter and some outlets for power outages at home. The installation was simple, taking only a few minutes with Velcro and zip ties. My charger has a 10 amp rate, and it fully charged in just a few hours. When the power goes out, we can run multiple AC devices and keep our phones charged."

"After using two of these batteries in my skoolie conversion for over a year, I'm pleased to report they have shown no loss of capacity. They power everything from lighting to my electric water heater without any issues. I even charged them in cold weather by accident, and they still work perfectly. If you're using them in cold conditions, I recommend considering a self-heating model for added security."

"I bought two of these 100 AH lithium batteries to replace my old marine batteries on the travel trailer. Together, they're 80 pounds lighter and have been fantastic. I boondocked for four days without any concerns about power. I love the Bluetooth feature, allowing me to monitor the batteries from inside my trailer. I'm very satisfied so far and am curious to see how long they last."
