What Are the Key Specifications of the CMF80L-BCI Battery?

The CMF80L-BCI features a 12V system, 650 CCA, and 80Ah capacity. Its AGM design provides spill-proof operation, vibration resistance, and a 3–5-year lifespan. Dimensions (8.5″ L x 6.9″ W x 7.5″ H) fit compact battery trays, while reverse terminal placement prevents cable strain. Ideal for vehicles requiring Group 80L batteries, it meets OEM standards for Honda CR-V, Acura MDX, and similar models.

AGM technology uses fiberglass separators to hold electrolyte, allowing faster ion transfer compared to traditional flooded batteries. This design enables 2-3x deeper discharge recovery and reduces internal resistance by 30%. The battery’s calcium-alloy grids minimize gassing, while its pressure-relief valves ensure safety during overcharge scenarios. For cold climates, the 650 CCA rating guarantees reliable starts down to -30°C, outperforming many conventional options.

How Does the CMF80L-BCI Compare to Conventional Flooded Batteries?

Unlike flooded batteries, the CMF80L-BCI’s AGM technology offers 2x faster recharge, 40% longer cycle life, and zero maintenance. It handles deep discharges better (up to 50% DoD) and operates at -30°C to 60°C. Flooded batteries degrade faster in vibration-prone environments, while AGM’s fiberglass matting resists shock, making it ideal for SUVs and hybrids with start-stop systems.

AGM batteries maintain stable voltage output during high-demand situations like simultaneous operation of infotainment systems, heated seats, and LED lighting. Their sealed construction prevents acid stratification issues common in flooded batteries, particularly in vehicles with irregular driving patterns. The CMF80L-BCI also demonstrates 85% charge retention after 30 days of inactivity versus 60% for flooded counterparts.

What Maintenance Practices Extend the CMF80L-BCI Battery’s Lifespan?

Keep terminals clean using a baking soda-water mix and dielectric grease. Avoid deep discharges—recharge if voltage drops below 12.4V. Use a smart charger to maintain 12.6–12.8V during storage. Annual load testing identifies capacity loss. Unlike flooded batteries, AGM requires no water refills but benefits from periodic equalization charges to balance cell voltage.

Implement a quarterly maintenance routine: inspect terminals for corrosion, measure resting voltage after 12 hours of inactivity, and clean battery surfaces from road salt. For vehicles with infrequent use, maintain charge levels above 12.4V using solar maintainers or plug-in tenders. Avoid jump-starting other vehicles, as reverse current flow can damage AGM cells. Storage in cool environments (10-15°C) slows self-discharge rates by 40% compared to garage storage.

“The CMF80L-BCI’s AGM design is a game-changer for hybrids and start-stop vehicles. Its ability to handle micro-cycles from regenerative braking without sulfation sets it apart. However, consumers must avoid using conventional chargers—AGM requires voltage profiles that match its absorption and float stages to prevent undercharging.”

FAQs

Q: Can the CMF80L-BCI be used in non-hybrid vehicles?

A: Yes, its high CCA and vibration resistance benefit all compatible models, though hybrids gain the most from its deep-cycle capability.

Q: Does the warranty cover voltage regulator failures?

A: No—manufacturer warranties (typically 3 years) exclude failures caused by improper charging systems.

Q: How to recycle the CMF80L-BCI?

A: Most auto shops and recycling centers accept AGM batteries. Redway offers a take-back program with $10 rebates.
