999 Heavy-Duty R20 D-Cell Carbon Batteries: Explosion-Proof Iron Shell for Gas Stoves and Water Heaters

Ensure your household appliances run safely and reliably with the 999 series high-performance D-cell batteries. Engineered with over 50 years of manufacturing expertise dating back to 1969, these batteries are specifically designed to withstand the demanding conditions of kitchen and utility environments. Featuring a reinforced iron shell, they provide a robust power solution for high-heat appliances, offering peace of mind through superior safety standards and long-lasting energy.

Key Benefits

Explosion-Proof Iron Shell:** Unlike standard plastic-wrapped batteries, these feature a heavy-duty iron casing. This protective layer acts as a thermal barrier, significantly reducing the risk of rupture or explosion even when used in high-temperature environments like gas stoves.

High-Heat Resilience:** Specifically optimized for appliances that generate heat, these batteries maintain stable discharge rates and structural integrity in the warm conditions typical of natural gas or liquefied gas stovetops.

Extended Ignition Life:** Engineered for efficiency, a single battery is capable of providing over 5,086 ignitions. Under standard household usage, one battery can reliably power your appliance for more than six months.

Advanced Leak-Proof Technology:** The upgraded internal formula and high-end manufacturing equipment ensure a secure seal, preventing corrosive leaks that can damage the delicate electronic components of your expensive appliances.

Eco-Friendly Composition:** These carbon batteries are mercury-free and environmentally conscious, meeting modern safety and ecological standards for household waste.

Key Specs

Model:** R20 (Size D / No. 1 Battery)

Chemistry:** Carbon-Zinc

Casing Material:** Reinforced Iron Shell

Quantity:** 2-piece card pack

Voltage:** 1.5V

Primary Application:** Gas stoves (Natural/LPG), gas water heaters, and large household appliances.

How to Use

1. Open the battery compartment of your gas stove or water heater.

2. Remove the exhausted batteries and check the terminals for any existing corrosion or debris.

3. Insert the new 999 R20 batteries, ensuring the positive (+) and negative (-) terminals align correctly with the markings inside the appliance.

4. Secure the compartment cover tightly to ensure the iron shell is protected from direct moisture.

5. Test the ignition to confirm a strong, consistent spark.

Care & Safety

Storage:** Keep batteries in a cool, dry place away from direct sunlight and high humidity to preserve shelf life.

Safety Warning:** Do not attempt to recharge these carbon batteries. Do not dispose of them in fire or mix them with different battery types (such as alkaline or lithium) or old batteries, as this may cause leakage or damage.

Maintenance:** If the appliance is not in use for an extended period, remove the batteries to prevent potential discharge.

Notes
