When selecting the right Vrla battery for your application, understanding the unique strengths of each series is crucial. At Minhua Battery, we offer four specialized series—HR (High Rate), MML (Long Life), MMG (Gel), and MN (Deep Cycle)—each engineered for distinct performance demands.

1. HR Series (high rate battery)

Keywords: high rate battery, high power output, fast discharge

• High-Power Discharge: Delivers instant high current for rapid discharge.

• Ideal Applications: Emergency lighting, power tools, pulse-load systems, UPS with high surge requirements.

2. MML Series (Long Life Battery)

Keywords: long life battery, float charge, standby power

• Extended Service Life: Optimized for continuous float (float charge) and standby use.

• Ideal Applications: Telecom backup, data centers, security systems, any float‐charge energy storage.

3. MMG Series (gel battery)

Keywords: gel battery, low self-discharge, wide temperature range

• Silica‐Based Electrolyte: Gelled electrolyte prevents stratification and water loss.

• Low Self‐Discharge: Excellent shelf life and minimal maintenance.

• Temperature Resilience: Performs reliably across –20 °C to +60 °C environments.

4. MN Series (Deep Cycle Battery)

Keywords: deep cycle battery, deep discharge, frequent cycling

• Robust Deep‐Discharge Performance: Engineered for repeated deep discharges without capacity loss.

• Ideal Applications: Solar energy storage, electric vehicles, off‐grid systems, frequent‐cycle UPS.

Cycle Life Comparison (20 HR @ 25 °C)

Note: Under identical test conditions, MN > MMG > HR > MML. Choose the series that best matches your cycle‐life requirements.

How to Choose the Right Series

1. High Surge Loads & Fast Discharge

   • Choose HR (High Rate) for applications requiring instantaneous high power.

2. Continuous Float or Standby Use

   • Choose MML (Long Life) for maximum longevity in float‐charge environments.

3. Frequent Deep Discharge Cycles

   • Choose MN (Deep Cycle) for superior deep‐cycle endurance.

4. Extreme Temperatures & Low Maintenance

   • Choose MMG (Gel) for environments demanding wide temperature tolerance and minimal water loss.
