2. Solar& wind energy storage system
3. O-grid & bad-grid hybrid sites
4. Floating applications for telecom sites

Benefits

1. Long life design for cyclic or oat application
2. Excellent charge acceptability and deep cycling performance
3. Excellent over discharge recovery capability
4. Superior charging & discharging ability in low current
5. Extend service life under high temperature

Technical Features

1. According to DIN-40742 and IEC-61427 standards, 20 years design life

2. Tubular plate & special gel electrolyte, which can prevent active material falling and avoid acid stratification
3. High stability and security, millions of batteries are in service
4. Higher thermal capacity & better thermal diffusivity2. Positive grid is made of special multi alloy, which overcomes the shortcomings of early capacity loss. It has long service life under both float charge and cycle utilization.
