When it comes to powering golf carts and other deep-cycle applications, battery reliability is everything. One failure can ruin a day on the course, a weekend RV trip, or disrupt solar power storage. The WEIZE 6V 210Ah BCI Group GC2 AGM Golf Cart Battery is designed to meet the high expectations of users who demand both durability and performance. In this blog, we take a technical deep dive into what makes this battery a standout in its category.
Battery Specifications at a Glance
Before we dive deeper, here are the key specifications:
-
Voltage: 6V
-

This battery is specifically engineered for deep-cycle applications, offering stable output and long operational life under cyclic loads.
What Is AGM Technology and Why It Matters
AGM stands for Absorbent Glass Mat, a technology that separates this battery from traditional flooded lead-acid models. In AGM batteries, a fiberglass mat holds the electrolyte between the battery plates, which offers several benefits:
-
Spill-proof and leak-resistant: The sealed design ensures no acid leaks, even if the battery is installed sideways.
-
Vibration-resistant: Great for golf carts and off-road vehicles that experience jostling and rough terrain.
-
Faster charging: AGM batteries typically accept charge more quickly than flooded cells.
-
Low internal resistance: This means more efficient power delivery and less energy loss during use.
AGM technology is particularly suitable for high-drain, deep-cycle applications, making it an ideal fit for golf carts that require consistent power across long distances.
Performance Analysis: Depth, Durability & Efficiency
1. Deep Discharge Capability
The WEIZE GC2 AGM battery is rated at 210Ah, which means it can provide 10.5 amps for 20 hours without dropping below a critical voltage. This makes it suitable for sustained energy demands, not just short bursts.
2. Long Cycle Life
With proper charging and care, this battery can withstand upwards of 1000 cycles at 50% Depth of Discharge (DoD). Compared to standard flooded batteries that often begin to degrade after 300–500 cycles, this is a significant performance advantage.
3. Low Self-Discharge
Thanks to AGM chemistry, the WEIZE battery only loses about 3% charge per month when stored — making it perfect for seasonal vehicles like golf carts and RVs.
4. Maintenance-Free Operation
No watering, no checking electrolyte levels. The sealed design makes the battery nearly maintenance-free, reducing user hassle and extending service life.
Applications and Compatibility
While marketed primarily for golf carts, the WEIZE 6V 210Ah AGM battery is highly versatile and compatible with a range of systems:
-
Golf carts (EZGO, Club Car, Yamaha)
-
Floor scrubbers
-
RV house batteries
-
Off-grid solar energy storage
-
Marine and trolling motor setups
-
Scissor lifts and mobility equipment
It fits the BCI Group GC2 standard, making it a direct replacement for similar deep-cycle batteries from brands like Trojan, Duracell, or Interstate.
