Then you can connect multiple batteries in series or in parallel with the Renogy Battery Interconnect Cable Review: Pour chalet et alimenté par panneau solaire et très bon prix 🥇 Review: Got tired of adding water to both of my 5 year old deep discharge flooded lead acid house batteries for my RV. My battery compartment is just large enough for two Group 31 batteries and these are near in size to that so I bought two of them. It also helps that the price on desertcart is very good! They look good and were easy to install. Quality looks very good, though that's just a visual check at this point in time for me. Note that the terminals have M8 screws - if you get battery cables with M8 (5/16) lugs there will be more metal at the end vs the 3/8 holes on my previous cables which rotted away. Nice removable caps on the battery terminals which help when connecting multiple batteries in parallel. See my photo of the final installation. I bought a Victron SmartShunt IP65 along with the batteries so that I would have more confidence in the state of the batteries when boondocking without shore (120VAC) power. There is a good datasheet for this battery on the Renogy website but that does not include two parameters that can help accuracy with the Victron. So I asked Renogy customer service for the information which they quickly provided! Bravo to them for this! The two parameters and their value are : Peukert’s Constant: 1.1 and Charge Efficiency: 90% I felt that the old batteries didn't have sufficient remaining capacity - though they were originally 120Ah each. Whether that was true or not I really don't know. See below for the reasons for this and why I got the Victron monitor - which I really like. I have a Renogy Rover 30A solar charger which shows the battery voltage and some kind of state of charge (SOC) number. But the voltage on a lead acid battery is an accurate measure of SOC only if the battery has sat completely idle (i.e. disconnected) for at least 24 hours which is a non-starter when you are camping. The solar controller doesn't know how much current is being drawn from my battery pack (both the house load and solar are connected directly to the battery) so it can't calculate any kind of reasonable load drop. From what I read the loaded voltage could be 0.5 to 0.7v or more below the resting voltage as related to SOC. Hence the uncertainty with the old batteries. The shunt battery monitor is in series with the negative battery terminals so it knows all the current in/out of the battery, plus voltages and temperature. So it can calculate SOC more accurately. Note, however, that all it can calculate is the percentage of the battery capacity. If you enter 200Ah as the net capacity for the battery pack and you use 100Ah then it will show roughly 50%. But just exactly what the net remaining capacity is for a battery that is a couple of years old is a difficult question to answer. If the actual capacity has degraded to 150Ah, then that 100Ah discharge is bringing SOC down to 33% which is definitely not good. Apparently the correct way to test actual capacity is to discharge it at the spec rate (100Ah divided by 10 hours equals 10A) until the voltage drops to 10.5V. You want the current to be constant even though the voltage is varying and you definitely want to stop when you get to 10.5V and then immediately charge it up again. I don't see myself setting up such a test fixture nor do I know any place that can do this kind of test... ## Features - MAINTENANCE FREE: Manufactured with thick absorbent glass mat (AGM) separators and advanced valve control technology, Renogy deep cycle AGM batteries are free of acid leakage and requires no frequent maintenance - Excellent discharge performance: Unique five-element alloy plate and specially processed plate grid ensures low internal resistance and high discharge current up to 10 times of battery rated output - LONG LASTING: Renogy deep cycle AGM batteries are made of high purity materials and reduce monthly self-discharge rate to less than 3% under 77℉(25℃), which is 5 times lower than the electrolytic submersion competitive products - Wide operating temperature range: Improved electrolytes formula, stable battery capacity and unmatched output performance under temperatures below 32°F (0°C) - Note: Battery is highly recommended to install upright If you have a special reason, you can mount the battery horizontally. Do not install the battery upside down ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B075RFXHYK | | Amperage | 50 Amps | | Batteries | 1 12V batteries required.

And when not in use, we recommend charging it 100% before storing it and recharging it after three months. **Q: Q: Do they come with the terminal bolts? if not what size do they take?** A: A: This Renogy AGM battery comes with two M8 x 1.25 x 20 mm terminal bolts. **Q: Q: Can I connect batteries in series and in parallel?** A: A: Yes, you can. The maximum number that can be connected in parallel is 4. In series, there are no limitations. **Q: Q: Can I connect a 100 Ah battery to a 200 Ah battery?** A: A: No, you can't. All the batteries you connect together should be the same capacity (Ah), the same voltage (V), and most importantly, the same battery type (AGM). And it would be better if they come from the same brand. **Q: Q: When using a charge controller, which battery type should I set?** A: A: You should choose the SLD battery settings. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***N on December 18, 2022* Pour chalet et alimenté par panneau solaire et très bon prix 🥇 ### ⭐⭐⭐⭐⭐ Review *by K***Y on October 24, 2025* Got tired of adding water to both of my 5 year old deep discharge flooded lead acid house batteries for my RV.

Holds a charge as advertised and responds to a solar panel charge to reach full capacity easily. It is reasonably heavy, but that's what I have gotten used to in rv batteries. The price is acceptable now. ## Frequently Bought Together - Renogy Deep Cycle AGM 12 Volt 100Ah Battery, 3% Self-Discharge Rate, 1100A Max Discharge Current, Safe Charge Appliances for RV, Camping, Cabin, Marine and Off-Grid System, Maintenance-Free - Renogy 500A Battery Monitor with Shunt, High and Low Voltage Programmable Alarm, Range 10V-120V up to 500A, 20ft Shielded Cable, Compatible 12V Lithium Sealed, Gel, Flooded Batteries,Black - Renogy 2000W Pure Sine Wave Inverter 12V DC to 120V AC Converter for Home, RV, Truck, Off-Grid Solar Power Inverter 12V to 110V with Built-in 5V/2.1A USB / Hardwire Port, Remote Controller --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/741675001-renogy-deep-cycle-glass-mat-absorbant-battery-12v-100ah-rv](https://www.desertcart.vu/products/741675001-renogy-deep-cycle-glass-mat-absorbant-battery-12v-100ah-rv) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-04*
