UPS battery used in 3 Note:
Actually available for all discharged UPS battery size and battery current, Laptop battery temperature of the working environment, storage duration and load characteristics are closely linked. If you are not actually the UPS power supply, use often cause the actual available capacity of the batteries is far less than the nominal capacity. To this end, the user should pay attention to the use of batteries, the following points:
1. Rechargeable battery end of discharge and open-circuit load, a large number of internally-generated lead acid batteries do, and adsorption on the cathode of the battery with the cathode form the so-called “sulfate”, which rises in the battery internal resistance, battery charge-discharge performance may be affected. Now commonly used in M type sealed lead-acid battery life of about 3 ~ 5 years.
2. For most of the UPS power supply in case, the battery after every discharge can be used to float within the charging circuit. To ensure the battery-charge placed in saturated state, usually requiring 10 ~ load time is 12 hours. Charge time is not enough to cause the Dell U4873 battery is charged, is not sufficient, so the actual available capacity of the battery is much smaller than the nominal capacity. Voltage 200V lower than in the city, has some of the UPS power failed to use the internal charging circuit for charging the battery up to saturation.
3. To ensure the battery has a good charge and discharge characteristics, long-term idling UPS power supply (UPS start blackout for more than 10 days), before re-use, it is best not to increase the load, so that the use of equipment, UPS power supply battery charging circuit of the float 10 to 12 hours before use. UPS back-up style for the use of the user when the UPS back-up is long-term work in the group, it is recommended at intervals of one month to allow UPS inverter power supply in the state for at least 2 to 3 minutes to To activate the battery.
Electric Vehicle Battery Maintenance 6 Skills
Technique, when a non-loss storage of electrical
If the battery is in storage in the state banned dissipation. Loss refers to the battery status is not making timely delivery after use. Saved battery status of the deficit, is it vulnerable lead sulfate crystals attached to sulfate, the pole plate, plug the electric ion channels that are not in sufficient survey, which decrease hp Pavilion dv2000 battery capacity. Idle mode power loss more and more of the severe damage to the battery. Therefore, the battery is idle, we should add power once a month, so that they can better maintain battery health.
2 periodic inspection techniques
The use of procedure if it is continued line of electric cars, a sudden drop in mileage in a short time more than ten kilometers, it is likely that at least one VGP-BPS2C battery occurs in the battery compartment alone systems, softening shed plate, plate active material phenomena such as short circuit. At this point in time, the battery should be repaired professional associations to check, repair, or distribution group. This could fairly be extended battery life, maximize cost savings.
Tips to avoid the three high-current discharge
Start electric car, manned, uphill, please help with the pedal to avoid as much as possible to the current high-current discharge. High-current discharge easily lead to lead sulfate crystallization, to the detriment of the physical properties of the battery plates.
The charging time to master the right skills 4
The use of the process should be accurate to the actual situation based charging, refer to the usual frequency of consumption and mileage situation and pay attention to the capacity of the size of the battery manufacturer to give instructions, as well as the performance of the matching charger, the charging current consider the size of the load parameters such as frequency of. General, are charged batteries in the night, with an average load time of 8 hours. If the flat discharge (it’s free mileage very short) is, the battery will soon be filled to continue excessive fees phenomenon occurs, leading to cell dehydration, fever, lower battery life. Therefore, the battery charge at a depth of 60% -70% of the best discharge a battery, can travel free on the actual use of one kilometers based on the actual conditions are transformed in order to prevent damage free.
5 tips to prevent exposure
Electric vehicles and is prohibited under the sun. Battery temperature is too high internal pressure makes the environment by increasing the cell pressure relief valve had to open automatically as a direct result of water loss in order to increase the battery while the sony VGP-BPS2A battery cells will inevitably lead to an excessive loss of water softening, decreased activity of the plate to accelerate charging cradle body heat, since the shell drums, distortion and other fatal injuries.
6 Tips to prevent the charging plug fever
Charger output plug loose contact surface oxidation phenomena, such as charging plug will cause fever, fever for too long will lead to short-circuit charger, direct damage to the chargers to unnecessary losses. Sun found that the situation be immediately replaced, or plug-oxide
