Product advantage: Battery pool shell all standard flame retardant pool shell, even if there is short circuit sparks, will not lead to a significant risk of loss of customer room and equipment (such as fire or explosion); high tin plate formula really ensure the deep cycle life and the number of cells; excellent and polar plate in the formation process, the plate is not easy the contamination of impurities, can reduce the self discharge of battery, ensure the battery capacity of the long-term stability is better than general products
1, good safety performance: normal use without electrolyte leakage, no battery expansion and rupture.
2, discharge performance is good: discharge voltage is stable, the discharge platform is gentle.
3, good vibration resistance: fully charged state of the battery is completely fixed, with 4mm amplitude, 16.7Hz frequency vibration for 1 hours, no leakage, no electricity
The pool expands and breaks and the open circuit voltage is normal.
4, good impact resistance: fully charged state of the battery from 20cm high drop to 1cm thick hardwood board 3 times. No leakage, no cell expansion
And breakdown, open circuit voltage is normal.
5, good resistance to over discharge: 25 degrees Celsius, fully charged state of the battery for constant resistance discharge 3 weeks (resistance value equivalent to the battery 1CA put
The electrical resistance is required, and the recovery capacity is above 75%.
6, over charge good: 25 degrees Celsius, fully charged state of the battery 0.1CA charge 48 hours, no leakage, no battery expansion and rupture, open
The road voltage is normal, and the capacity maintenance rate is above 95%.
7, good resistance to high current: fully charged state of the battery 2CA discharge 5 minutes or 10CA discharge 5 seconds. No conductive part fuse, no appearance
[installation, operation and maintenance]
The battery is connected:
The batteries or batteries with the same actual capacity can be connected in series;
The batteries or batteries with the same actual voltage can be connected in parallel;
The connection should be close, to prevent sparks, bad contact, wash the contact surface with soda water.
Positive and negative poles must not be reversed or shorted.
The battery charging:
Float (limit voltage, current control): charging voltage 13.56-13.8V,
The maximum current shall not exceed 1.75A; 25 DEG C, the battery charge current to the whole small
At 2mA/AH;
Cycle use (fill, stop, release, charge): charging voltage 14.1-14.7V/,
The maximum current is not greater than 2.1A;
Caution: the battery can not be used in airtight or high temperature environment, away from the fire source!
Note: when the ambient temperature is lower than 20 or higher than 30, the charge voltage of the battery should be adjusted
The standard is 18mV/ centigrade.
The preservation:
The battery is suitable for storing in low temperature, dry, ventilated and clean environment
Characteristics of OT (6V/12V) series products of Ott multi battery
Trough formation ensures that the battery reaches 100% capacity and the battery balance is optimized.
The high reliability pole column double seal structure has greatly improved the impact resistance and sealing performance, and ensured the electrolyte will not seep out, thus improving the reliability of the product.
Safe and reliable, with domestic advanced explosion-proof safety valve has considered acid tablets, opening and closing the valve pressure and explosion proof, acid mist filtering function accurately, once the overcharge, can release the excess gas, does not make the battery burst, mist escape.
Using ultra pure raw and auxiliary materials and additives, special formulations of electrolyte, with small internal resistance, high rate characteristics, strong acceptance of the characteristics of the charge.
The use of advanced technology (alloy process, paste process, electrolyte formulation, epoxy sealing technology), to ensure good performance of products.
Main features of storage battery:
Design for USP applications
- long life (25 degrees Celsius float, the design life of up to 5~8 years)
More safe (shell using flame retardant material, product safety certification through UL)
Self discharge is small (storage time is 1~2 years)
Good sealing (sealing efficiency up to 99.9%)
Service Excellence (3 years warranty, quality assurance)
1, the battery has a strong ability to resist deep discharge, and it can still be connected to the load after 100% discharge, and the capacity can be recovered within four weeks after charging. 2, because the battery is colloidal solid, so the electrolyte concentration is uniform, there is no acid layering phenomenon. 3, the acid concentration is low, the plate corrosion is weak, and the use of unique tubular plate, so the battery life is long. 4, the battery plate adopts antimony free alloy, the battery self discharge electrode is low. After 50% years of storage at 20 degrees C, there are more than two capacity, that is, no additional power in two years. 5, super strong withstand deep discharge and high current discharge capacity, with overcharge and over discharge self-protection performance. 6 gel electrolyte, no internal short circuit. The heat capacity is large, the heat dissipation ability is strong, and the thermal runaway phenomenon of the common accumulator can be avoided, so the operation is very reliable in the high temperature operation, and the battery does not generate "drying" phenomenon, and the working temperature range is wide. 7, the use of high sensitivity low pressure umbrella type valve (German SunShine Co patent), so that the use of batteries safer and more reliable. 8, the use of multi layer acid resistant rubber ring sliding seal, to ensure the service life of the late pole sealing performance.
