Gel Battery Features

1. Long Service Life

Heavy duty lead-calcium grids ensure mild corrosion and enable a long designed service life of 10 years standby use under optimal float charge conditions and below optimal operating temperature of 25℃.

2. Patent Designed Construction

SPW batteries are equipped with PE compound separator construction, which ensures that

gel electrolyte is distributed evenly through-out the inner battery and ensures the best evenness of all parts of the battery.

3. Triplex Sealed Construction

Valve regulated sealed construction and triplex strengthened sealing on terminals and posts prevent electrolyte leakage, and guarantee the air tight and liquid tight state of batteries in normal operation and prevent external air from entering battery inner.

4. Low Self Discharge

Because of the use of lead-calcium grids alloy, SPW batteries have low self discharge and reliable performance. In room temperature, self discharge ratio per month of SPW battery is about 2% of the battery capacity.

5. High Security

SPW batteries are equipped with explosion-proof safety valves to prevent production of

redundant gas. And the construction is designed to prevent setting fire to the internal battery in case sparkles approach.

6. High Efficiency of Recovery

Unique formulas are used in lead paste of positive post and ensure the battery can be recharged easily to a normal level.

7. No Electrolyte Stratification

Special additives are use in electrolyte to give it a gelatinous consistency without flowing, leaking or stratification, and make all parts of plates react evenly.
