OPzV batteries

OPzV batteries

OPzV 2-800-Y Product Feature OPzV seires is the tubular GEL solar battery. Floating design life: 20 years at 25℃ Cycle life(2V): >2000 at 80% DOD and 6000 at 25% DOD Self-discharge rate: ≤2%/Month High charge acceptance performance Wide operation temperature range: -40℃~70℃ Storage life:...

Product Details

OPzV batteries are designed to have a large amount of stored current discharged between charging sessions, Self-discharge rate is ≤2%/Month, Wide operation temperature range is -40℃~70℃, with very heavy non-porous battery plates to withstand repeated major discharging and charging cycle (deep cycle). The CHENGYU POWER OPzV battery uses a different chemistry for the plates active paste material, and a slightly stronger electrolyte than normal battery electrolyte, and Battery case is made of high strength ABS and durable design, thus the CHENGYU POWER range features 30% higher cyclic life with 10 years of float life when compared to the standard Duration range.

Charging and handling 

• Never charge the battery in a sealed container.
• Never disassemble the battery.
• Never short-circuit battery terminals.
• Never incinerate batteries, for they may explode.
• Do not press and/or bend the terminals, or overheat them.
• Do not mix old and new batteries together, neither use batteries of different types or brands.
• Do not dispose of with household waste.
• Be sure to use the specified charger for battery, and follow the charging instructions correctly.
• Be sure to charge the batteries between the temperatures 0℃ /32oF to 45℃ /113oF.
• Be sure to position batteries securely, protecting them from abnormal shocks and /or vibration.
• Be sure to keep sufficient space between batteries for ventilation (where possible>10mm).
• Be sure to install batteries in a cool and well ventilated place.
• The surrounding temperature must remain between -20℃ /4oFto 40℃ /104oF during storage.
• Recharge the batteries at least every 6 months during storage.

Be sure to consult CHENGYU engineers any time you are to use CHENGYU VRLA batteries for your products, or preparing your technical specifications of CHENGYU VRLA batteries.
