Structure & Characteristics

Benefits of Calcium Lead Grid Technology

- Benefit 1.
- Distilled water supplementation free
- As the lead-antimony conventional battery incurs unnecessary localaction inside battery due to the effects of antimony ion during battery use and discharges gas by electrolyzing water contained in electrolyte, the amount of electrolyte is decreased rapidly. The battery performance is deteriorted and operating life reduced unless distilled water is supplemented fequently to compensate for such decrease of electrolyte. Speedmate battery, however, uses specially alloyed calcium-lead, which leads to extremely low level of electrolyte decrease, Hence, if the charging system of vehicle remains error-free until the battery is worn out there is no need to supplement distilled water at all
- Benefit 2.
- Recharging free
- Due to the phenomenon of self-discharge, the lead-acid battery is characterized by its charged power being consumed even when the battery is not in use, such as during storage. The reason behind such phenomenon is that the impurities contained in lead alloy induces local action, causing electric energy to be consumed. Compared with the lead-acid battery, Speedmate battery uses carefylly selected, highly refined lead alloy, rendering extremely low rate of self-discharge, and maintaining high performance even during long-term standing.
- Benefit 3.
- Overcharge risk free
- The battery mounted on vehicles can always be charged while vehicles are in operation. In general, the current being charged is adjusted to high or low level by the regulator which controls the size of voltage. When battery is in thestate of near full charge under the condition of voltage already set, the value of current being charged must be decreased to prevent battery from being overcharged to maintain high performance for a long time. As shown on graph, the charging current of Speedmate’s Calcium battery is reduced to extremely low level when the battery is in near full-charge state, eliminating to near zero the danger of battery being overcharged.
- Benefit 4.
- Thermal runaway free
- When battery is in near full-charge state while battery is being used in hot places [temperature approximately 70℃], the current being charged must be decreased to prevent battery damage resulting from overcharging. The charging current level of lead-acid battery decreases at initial stage but rises again soon due to the effects of a few kinds of substance contained in the grid alloy, and the grid is damaged and performance deteriorated due to this thermal phenomenon. Speedmate battery, however, is free of substance containing such harmful effects, and the current being charged becomes extremely low level when battery is fully charged in high-temperature, leading to the prevention of overcharging.
