Battery Application and Installation
●The battery being is not being used in the application for which it was designed
●The battery is not the correct size for the application
●The equipment has excessive electrical accessories
●The battery cables have not been properly adjusted to fit the battery terminals
Service and Maintenance
●The battery has been stored for a long time and no supplementary charge
●The equipment setting parameters for battery do not according to supplier’s recommended and do not adjust
●Battery temperature compensation functions do not turn on and properly install the battery temperature probe.
●Battery bolts loosened or over-torquing
Visual Inspection
●Battery connection is wrong
●Container or cover show signs of stress, damage or high temperature.

As we all know, UPS power plays an important role in our work and daily life, it is usually the backup power supply of department stores, supermarkets, banks, and the base stations and could prevent the equipment from outage and regulate the voltage, so UPS uninterruptible power supply makes our work and daily life well organized. However, UPS power is usually considered maintenance free and the necessary maintenance is always ignored, thus reducing its service life.
The normal floating life of maintenance-free sealed lead-acid battery is 3-5 years at room temperature (usually at 25℃) under normal conditions and in regular use. But the unreasonable maintenance of battery has greatly reduced the service life of UPS power supply.
Here are three tips for maintenance:
1.The ambient temperature of battery should be 0-40℃ to avoid direct sunlight;
2.Normally, the battery should be charged and discharged every 3 to 6 months and the charging time should be not less than 10 hours after discharged.
3.UPS power should be charged every 3-6 months if long time idle. 

Sacred Sun maintenance-free high temperature (HT) battery could work in air-conditioner absent conditions and its design service life is 10 years at 35℃. Why HT series battery could perform properly at high temperature? Some main reasons are listed as follows:

1.Vertical ribs with tapered structure and horizontal ribs with ellipsoidal structure are adopted to expend the service life of grids.
2.Lead paste with high density is adopted to increase the integration points among active material particles.
3.High temperature & humidity is adopted in curing process to form stronger structure of active materials.
4.High assembly pressure is adopted to prevent the active materials from softening.
5.Acid volume is limited to prevent over-discharge at high temperature.
6.Special carbon material is added to the negative plate to prevent sulfation of negative plates and improve charge acceptance.
7.Low density electrolyte is adopted to reduce the corrosion rate of positive grids. The electrolyte density of finished batteries should be no more than 1.285g/cm3.
8.The bus-bar structure and related welding process is optimized so as to improve the corrosion resistance of bus-bar.
With its superb cycle life, fast charging acceptance capability and favorable operation state at partial status of charge (PSOC) conditions, it is suitable for floating or cyclic applications such as high temperature BTS, unstable grid BTS, remote area BTS, and solar (wind) energy storage system.
