Renogy 12v 100ah Deep Cycle Battery

12v 100ah Deep Cycle Battery. The heavy-duty lead-calcium grids contained within this battery are anticipated to have a lifespan of up to ten years. Additionally, the design of the PE compound separator allows gel electrolyte to be distributed evenly throughout the interior of the battery, which results in maximum consistency in output.

Amazingly, when compared to the Renogy AGM 100ah batteries, this GEL variant is capable of almost doubling the number of charge cycles. This is one of the many reasons why it is so popular (1100 vs 600 in the AGM model). On the other hand, if you require significant bursts of amps, such as while operating a power tool, you should almost always go with an AGM battery rather than a Gel battery.

The design of the battery is safe in that it does not off-gas or leak, and it has a low self-discharge rate of 3 percent per month. This indicates that the battery will still retain around 60 percent of its charge even after being stored in a closet for a whole year.

It should come as no surprise that this Renogy battery and the Renogy Solar Starter Kit are frequently seen in RVs and do-it-yourself campervans all over the world; they are frequently combined with one another.

  • Good longevity
  • Low maintenance. Renogy Deep Cycle Pure GEL Batteries are built with gel suspended electrolyte and utilize cutting-edge valve controlled technology. As a result, these batteries prevent acid leakage and reduce the need for routine maintenance.
  • Lengthened duration of service. In standby applications, corrosion-resistant grids can have a design life of up to 12 years, and in cycling applications, they can have a design life of more than 750 charge/discharge cycles at 50 percent depth of discharge.
  • Long time on the shelf. Renogy deep cycle pure Gel batteries, which are made of high purity materials, have a monthly self-discharge rate that is reduced to below 3 percent at 77 degrees Fahrenheit (25 degrees Celsius), which is 5 times lower than their flooded counterparts.
  • Deep discharge recovery. The combination of a specific plate composition and a revolutionary gel electrolyte offers an outstanding capacity for recovery after an excessively deep discharge.
  • Excellent safety. Explosion-proof safety valves are standard on Renogy batteries, which are designed to prevent the creation of redundant gas. In the event that sparks come close to the internal battery, the structure is made in such a way as to prevent it from catching fire. At 25 degrees Celsius, the product has a shelf life of nine months. Internal resistance: 7. 1Mω
  • Power Battery Powered is the Type of Source.


  • High price point

The Sealed Lead Acid (SLA) batteries that make up the Renogy 12V 100Ah batteries have a nominal voltage of 12 volts, while the lithium batteries have a voltage of 12.8 volts.

The ‘Pure Gel’ and ‘Hybrid Gel’ batteries each have a nominal capacity of 100Ah, while the ‘AGM’ batteries have a capacity of 104Ah. Batteries made with lithium iron phosphate (LiFePO4) have a capacity of five hours and one hundred ampere-hours (also often labeled as 0.2C capacity).

The real capacity of the SLA (AGM, Gel Cell) batteries declines dramatically when the discharge current is raised. This is common for all lead-acid batteries, not only Renogy types; it does not apply specifically to Renogy batteries. On the other hand, the real capacity reduction of lithium batteries is virtually unnoticeable.

Size and Weight
Every single one of the Renogy 12V 100Ah batteries belongs to BCI Group 31 or is an extremely close fit:

  • AGM and “Hybrid Gel” batteries fall under the BCI Group 31 category.
  • The ‘Pure Gel’ battery is frequently classified as a BCI Group 31 battery, although it is really slightly too long (by 0.2 inches, or 0.5 cm). The ‘Pure Gel’ battery can fit into most compartments for 31 batteries, but you should verify it first.
  • If the battery compartment for the BCI Group 31 battery is somewhat taller than the nominal height of the group 31 battery, the Renogy RNG-BATT-LFP-12-100 lithium battery may be able to fit into it. Alternatively, it may fit into the BCI Group 24T battery compartment (9.7 vs 9.0 inches – less than of an inch difference),
  • The Renogy RBT100LFP12S-G1 battery has a relatively close fit to the BCI Group 65 batteries, but it may also be kept in the battery compartment that was designed for the group 31 batteries.

Size and weight

The weight of AGM and Gel batteries ranges between 27.2 and 29.9 kilograms (between 60 and 66 pounds), whereas the weight of lithium batteries is between 28.1 and 26 pounds (12.75 and 11.8 kg respectively) The difference in weight is noticeable, and switching from lead-acid to lithium batteries might result in substantial weight reduction.

This could be particularly useful for applications such as boats, electric automobiles, recreational vehicles, and other similar vehicles. It can be compare to other top rated marine battery.

Currents for Charging and Discharging Batteries

RNG-BATT-LFP-12-100 lithium battery features cut-off at 150 Amps, while RNG100LFP12S-G1 lithium battery may provide 130 Amps for 60 seconds and features cut-off at 150 Amps. AGM battery may provide 1100 Amps for 5 seconds, ‘Hybrid Gel’ may provide 1000 Amps for 5 seconds, ‘Pure Gel’ doesn’t state maximum allowed current, but it can provide 335 Amps for 5

The maximum current that may be safely drawn is directly proportional to the battery’s internal resistance, which is 4.9 m for AGM batteries, 6.0 m for ‘Hybrid Gel’ batteries, 7.1 m for ‘Pure Gel’ batteries, and 30 m for lithium batteries. For instance, the voltage drop of an AGM battery during discharge with 100 Amp is around 0.5 Volts, but the voltage drop of lithium batteries during discharge with the same 100 Amps is approximately 3 Volts, which is a significant difference.

On the other hand, lithium batteries have a maximum charging current of 50 Amps, which enables these batteries to receive a full recharge in a relatively short amount of time. The maximum charging current for an AGM battery or a “Hybrid Gel” battery is 30 amps, but the maximum charging current for a “Pure Gel” battery is “only” 15 amps.

When charging these batteries, one should make use of intelligent battery chargers and charge controllers, and then adjust the settings on those devices so that they are appropriate for the type of battery that is being charged.
