All these batteries have been tested and verified before sending to the market. Each and every battery features 100% electric shock testing, along with the 100% current test and pressure test to guarantee great efficiency.
The vent caps have been tailored to avoid the leakage of any acid from the batteries.
All the batteries have fusion weld to decrease corrosion, and to have high integrity.
Each of these battery features high-purity calcium alloy which increases their life and minimizes corrosion.
Each battery features negative paste formulation which increases the life of the battery and also makes its performance more efficient.
The framed positive grid in all the batteries is to resist vibration and improve cycling performance.
The batteries remain cooler for a long time period which results in their long life. This happens through the robust envelope separators.
