How Does the Group 27DC Battery Perform in Marine Environments?
The Group 27DC excels in marine settings due to its corrosion-resistant terminals and deep-cycle design. It delivers consistent power for trolling motors, fishfinders, and bilge pumps. Its 180-minute reserve capacity ensures extended runtime, while the robust casing prevents damage from waves or rough waters. Users report reliable performance in saltwater and freshwater conditions.
Marine applications demand batteries that can withstand constant moisture and salt spray. The 27DC’s lead-calcium alloy grids reduce gassing by 38% compared to standard lead-antimony designs, minimizing water loss in humid conditions. Field tests show the battery maintains 89% of its starting power after 200 saltwater fishing trips when properly rinsed after use. For optimal performance in brackish environments, pair with stainless steel terminal protectors and check specific gravity monthly during peak season.
| Environment | Capacity Retention | Recommended Maintenance |
|---|---|---|
| Saltwater | 89% after 1 year | Monthly terminal cleaning |
| Freshwater | 93% after 1 year | Quarterly voltage checks |
Can This Battery Handle Extreme Temperatures?
Yes. The 27DC operates between -40°F and 140°F. Its thick lead plates resist sulfation in cold weather, while the high-density electrolyte solution minimizes evaporation in heat. Testing shows 92% capacity retention after 12 months in desert climates, outperforming competitors like Optima and Interstate.
In freezing conditions, the battery’s cold-cranking amps (CCA) remain stable due to patented plate spacing that prevents ice crystal formation. Arctic users report successful engine starts at -22°F without external heating aids. For desert RVers, the dual-stage vent system reduces water loss by 27% compared to standard marine batteries. When operating above 100°F, add distilled water every 6-8 weeks and avoid direct sunlight exposure to prolong service life.

- Voltage: 12V
- CCA: 675
- AH Capacity: 115
- Dimensions: 12.4″ x 6.8″ x 9.4″
- Weight: 43.5 lbs
- Terminal Type: SAE Posts

How Does Maintenance Compare to AGM Batteries?
Unlike maintenance-free AGM batteries, the 27DC requires quarterly electrolyte checks. However, its translucent casing simplifies fluid monitoring. Users save $50-$150 vs AGM upfront costs but invest 10-15 minutes monthly in terminal cleaning and voltage checks. Proper maintenance extends lifespan to 4-6 years.
Where Can You Purchase This Battery?
Exclusive to Walmart stores and Walmart.com. Priced at $109-$139, it’s frequently discounted during spring fishing seasons and fall RV prep months. Third-party sellers on Amazon charge 20-30% premiums. Verify production dates (stamped on case) – batteries older than 6 months may have reduced capacity.
What Safety Features Protect Against Acid Leaks?
- Double-sealed vent caps
- Acid suspension matting
- Impact-resistant polypropylene case
- Overpressure relief valves
- Tip: Always transport upright – even 15° tilting can cause leaks in non-AGM batteries
“The 27DC’s balance of price and performance makes it our top recommendation for budget-conscious boaters. While lithium-ion dominates the premium market, this battery’s 400+ cycle rating at half the cost delivers exceptional value. Just remember – always use a marine-rated charger to prevent plate warping.”

FAQs
- How long does the 27DC last running a RV fridge?
- Approximately 2.3 days powering a 10 cu ft RV refrigerator (1.5A draw) without recharge. Pair with solar panels for extended boondocking.
- Can I use this battery in a golf cart?
- Not recommended. Golf carts require 6V or 8V batteries in series. The 27DC’s 12V configuration suits parallel connections for 12V/24V marine/RV systems.
- What’s the warranty coverage?
- Walmart offers 1-year free replacement + 2-year prorated warranty. Marine use reduces coverage to 90 days – keep purchase receipts for claims.
