6-EVF-100 12V 100Ah Tubular Gel Battery: Specification Guide for Solar, EV, and Industrial Buyers (2026)
For buyers searching “gel battery” — a search term up 11.06% year-on-year on Alibaba — the 6-EVF-100 is the capacity sweet spot. It delivers 100Ah in a single 12V block, which is the most flexible building block for solar storage banks, electric vehicle propulsion packs, floor cleaning machines, and telecom backup systems. This guide walks through CHISEN’s 6-EVF-100 factory specifications, explains the real-world performance in each application segment, and shows you how to evaluate competing gel SKUs before placing a 20GP order.
The 6-EVF-100 belongs to CHISEN’s EVF series, which uses tubular gel technology rather than flat-plate AGM. Tubular gel delivers three structural advantages over AGM: zero electrolyte stratification in partial-state-of-charge duty, zero acid spill risk in any orientation, and significantly better recovery from chronic undercharge conditions. Those three advantages matter most in solar storage, electric vehicle propulsion, and industrial applications where the battery sits in harsh duty cycles for years.

The 6-EVF-100 is rated at the C3 (3-hour) rate rather than the C2 rate used for DZF/DMF series. This reflects the application difference: the EVF series is designed for traction and deep-cycle applications where the discharge profile is 3–5 hours of moderate current, not the 1–2 hour high-current profile of an e-bike primary pack.
What Each Specification Means for Your Application
Tubular Plate Construction. The “EVF” designation indicates tubular positive plates, where the active material is held in microporous tubes rather than pasted onto a flat grid. Tubular plates deliver 1.5–2x the cycle life of flat-plate AGM at deep discharge (80% DoD), which is the relevant metric for solar storage and EV propulsion. The trade-off is roughly 15% higher unit cost and roughly 20% heavier weight per amp-hour.
Rated Capacity at 3hr (100Ah). A 6-EVF-100 at the C3 rate delivers 33 amps continuously for 3 hours before reaching 10.5V cutoff. For solar storage, that is enough capacity to run a 1,000W inverter at 50% load for 1 hour, or a 200W inverter at 50% load for 5 hours. For EV propulsion (floor scrubber, small electric vehicle), that translates to roughly 4–6 hours of continuous operation depending on load.
Cycle Life ≥ 600 cycles at 80% DoD. This is the critical number for solar storage and EV applications. At 600 cycles with daily 80% depth discharge, the battery delivers approximately 600 days of service — about 1.6 years in heavy solar duty. For lighter applications (50% DoD), the cycle life extends to roughly 1,200 cycles, or 3+ years of service. Compared to a generic 12V 100Ah AGM that delivers 200–300 cycles at 80% DoD, the tubular gel advantage is 2–3x.
Operating Temperature -40°C to +60°C. The EVF series uses a higher specific gravity electrolyte than the DZF/DMF series, which extends the low-temperature operating range. For cold-storage warehouses, Nordic telecom sites, and northern climate applications, this temperature range matters. The upper limit of +60°C is also higher than the standard +50°C of AGM batteries, making the EVF series suitable for under-hood EV applications and hot-climate solar installations.
Self-Discharge ≤ 2% per month. The gel electrolyte suppresses self-discharge more effectively than AGM. For seasonal applications (summer-only marine, winter-only backup), this means a 6-month storage period results in only 12% capacity loss — versus 18% for AGM. Your customers will not return from storage to find dead batteries.
Internal Resistance ≤ 5.5 mΩ. Low internal resistance is critical for high-current applications. The 6-EVF-100 can deliver 800A for 5 seconds without damage, which is sufficient for engine starting, motor inrush current, and inverter surge conditions. Generic 12V 100Ah batteries typically specify internal resistance of 8–12 mΩ, which limits their surge capability and accelerates heat buildup under load.
Drop-In Replacement Compatibility Across the EVF Series
The EVF series shares the same BCI group footprint as the standard lead acid 12V 100Ah form factor, but the tubular gel construction requires the charger to be set to gel-specific voltage parameters. If you are replacing flooded or AGM batteries with the 6-EVF-100 in an existing system, the charger must be reconfigured to 14.2–14.4V absorption (not 14.4–14.8V for AGM) and 13.5–13.8V float.
The 6-EVF-100 fits the standard battery tray used in:
| Application | Standard Tray Size |
|---|---|
| Floor scrubber / sweeper | 330 × 175 × 240 mm |
| Small electric vehicle (golf cart, AGV) | Group 27 footprint compatible |
| Telecom BTS cabinet | 12V 100Ah standard bay |
| Solar storage bank | Standard 12V 100Ah rack |
| Marine house bank | Group 27 standard tray |
If your existing tray is sized for a different BCI group (Group 24, Group 31), the 6-EVF-100 will not fit without modification. The 6-EVF-100 is the Group 27 footprint. CHISEN can provide dimension-matched variants (6-EVF-100N at 32.5 kg, 6-EVF-100E at 33.2 kg) for applications where vibration resistance or extended cycle life is the priority.
Application-Specific Selection: Which 6-EVF Variant Fits Your Use Case
| Application | Recommended Variant | Why |
|---|---|---|
| Solar home system (PSOC duty) | 6-EVF-100 standard | Gel recovery from partial state of charge |
| Floor scrubber / sweeper | 6-EVF-100 standard | Daily deep cycle, vibration resistance |
| Telecom BTS backup | 6-EVF-100 standard | Wide temperature range, low self-discharge |
| Small electric vehicle (AGV, golf cart) | 6-EVF-100N | Enhanced cycle life, daily deep discharge |
| Harsh environment (mining, marine) | 6-EVF-100E | Highest vibration resistance, longest cycle life |
| UPS battery bank (data center) | 6-EVF-100 standard | Float duty, low self-discharge |
For solar home systems where the battery sits at 40–80% state of charge for extended periods (cloudy seasons), the gel electrolyte’s recovery characteristic is decisive. AGM batteries in the same duty cycle lose 30–40% of their cycle life; gel batteries lose less than 10%.

Frequently Asked Questions
What is the difference between 6-EVF-100 and 6-DMF-100?
The EVF designation indicates tubular gel construction with higher cycle life and wider temperature range. The DMF designation indicates flat-plate sealed lead acid (AGM-equivalent) at lower cost. For deep-cycle daily use (solar, EV, scrubber), EVF is the correct choice. For float backup (UPS, security), DMF is sufficient.
Can I use a standard AGM charger on a 6-EVF-100?
You can, but you should reconfigure the absorption voltage to 14.2–14.4V (not the AGM-specific 14.4–14.8V). Charging gel at AGM voltages accelerates grid corrosion and shortens cycle life. CHISEN supplies gel-compatible chargers at $45 per unit at 500-unit MOQ.
What is the cycle life at 50% DoD?
At 50% depth of discharge, the 6-EVF-100 delivers approximately 1,200 cycles at 25°C. At 80% DoD, 600 cycles. At 100% DoD, approximately 350 cycles. These are factory-tested figures at C3 discharge rate.
Can the 6-EVF-100 be mounted in any orientation?
Yes. Gel electrolyte is fully immobilized, so the battery can be mounted on its side or even upside down without leakage. This is a structural advantage over flooded and AGM batteries, which must remain upright.
What is the warranty?
24 months from B/L date for manufacturing defects. The longer warranty (compared to the 12-month warranty on DZF/DMF series) reflects the longer cycle life of the EVF series. Warranty does not cover improper charging, deep discharge below 10.2V, or operation above 65°C ambient.
