Product Details

VRLA Battery 12V33AH Sealed Lead Acid AGM Storage Battery

Reading is technical handbook prior to operation to ensure constructing correctly. Batteries shall be checked one by one to prevent from abnormal voltage prior to installation. Insulation tools should be used when installing & removing conductive connection slices due to higher serial voltage to protect from electric hit. During transportation & installation, battery’s short-circuit must be paid attention to because the battery delivered is electric.

Q1: How much does shipping cost?
  A: The quotation is FOB in our company.
Q2: What is the price about your products?
  A: The battery has different price according to different specification and capacity. If you have any questions, please contact the salesmen.
Q3: Where the product can be used?
  A: Company products can be widely used in a variety of condition, you can use our battery if you need electric.   (Usage: Home power system, Power station system, Uninterruptible power supply, Emergency power supply, Solar Street light, monitoring system, automation equipment, Electric-vehicle, etc.) If you want to know more detailed information, please contact the salesmen.
Q4: What are the advantages of your company products?
  A: The advantages of battery are low temperature resistance, heavy load discharge performance, long operating life and good duration performance.

Installation of storage battery
(1). Battery may be installed in any direction (with the exception of turning upside down ) connection must be according to serial/parallel circuit. It is not allowable for incorrect and reverse pole connection.
(2). Oxides and dirty on battery’s terminals contact surface should be removed with sandpaper or iron brush to reduce contacting resistance and prevent from producing heat. A layer of vaselinum oil must be coated prior to installation. Check the system’s general voltage and positive & negative pole before power is on to ensure right installation.
(3). Shorten connecting cables if it is possible. Voltage drop produced should be taken consideration into selection of cables and for the cable’ specification, output capacitance shall not be as a unique factor.
(4). Battery may be shunted to reach its capacitance required. To reduce voltage drop, shunted connecting wire shall be most probably short.
(5). Batteries with different capacitance and /or performances and /or new & old degree shouldn’t be taken into service together.
(6). Battery should avoid installing inside on enclosed device. Good air ventilation is required. Don’t mount it nearby heat generating objectives e.g. transformer etc.
(7). Torque value for connecting battery shall be 11.3 N/M.
(8). Circuit switch shall be in position of “off” and the battery’s positive/negative pole shall be in that of corresponding connection of charger’s (load’s) positive/negative pole.
