Product Description

6FM-7 is a general purpose battery up to 5 years in standby service or more than 260 cycles at 100% discharge in cycle
service. As with all Baace batteries, all are rechargeable,
highly efficient, leak proof and maintenance free.

Features

- Service Life:
  - Standby Service: Up to 5 years. This refers to applications where the battery is kept fully charged and only used occasionally, like in UPS (Uninterruptible Power Supply) systems or emergency lighting.
  - Cycle Service: More than 260 cycles at 100% depth of discharge (DoD). A “cycle” is one full charge and discharge. This makes it suitable for applications like solar power storage or electric vehicles where regular cycling occurs.
- Rechargeable: Can be recharged hundreds of times, depending on usage conditions (e.g., depth of discharge, temperature, charging method).
- Highly Efficient: Likely refers to good energy retention and low self-discharge rate (typically 2-3% per month for VRLA batteries at room temperature).
- Leak-Proof: Sealed design prevents electrolyte leakage, making it safe for various orientations and environments.
- Maintenance-Free: No need to add water or check electrolyte levels, unlike traditional flooded lead-acid batteries.

Documents & Drawings

Self-Discharge: If stored unused, it loses a small percentage of charge monthly. Keeping it in a cool, dry place extends shelf life.
Charging: Requires a compatible charger (12V, with appropriate current limiting) to avoid overcharging, which can reduce lifespan.
Cycle Life: The 260+ cycles at 100% DoD is decent, but partial discharges (e.g., 50% DoD) could extend the total number of cycles significantly.
