Operations & Safety

For getting the maximum life and performance out of the battery, the following recommendations have to be followed:

Operating Environment

  • Temperature of 15-30°C. Recommended normal operating temperature is between 25-27°C. High temperature will reduce battery life dramatically. A 10°C rise in temperature will reduce battery life by half.
  • Relative Humidity less than 90%
  • Ensure adequate ventilation where the batteries are fitted.
  • Avoid direct sunshine
  • Keep far from fire and heat
  • Keep far from chemical reagent or solvent
  • Keep battery clean and dry.

There’s no free electrolyte present in the battery to affect the customer during handling. In case of acid leakage due to container crack, do the following:

  • Drops of acid on clothing: Treat with soap and water. Rinse it with large quantity of water before drying it.
  • Drops of acid in eyes: Rinse continuously for about 5 minutes in clean running water and then immediately consult a doctor.
  • Batteries should not be kept in air tight enclosures/closed units/systems which does not have ventilation. Adequate ventilation should be provided.

Charging & Discharging Requirements

  • Recommended float Voltage of 13.5-13.8V per 12V battery module. Maximum float charging voltage should not exceed 13.8V per 12V battery at 27°C. If the ambient temperature is higher then float voltage should reduce by 0.004V per cell or 0.025V per 12V battery for every degree rise in temperature. This is the most misunderstood aspect of battery charging since even a miniscule increase in charging voltage leads to overcharge resulting in inherent water loss in the battery, leading to loss of life and performance.
  • Charging current of maximum 20% of C20 capacity. i.e. for a 100AH battery maximum charging current should be 20 Amps. With regards to minimum charging current, batteries need minimum of 10% of their capacity as charge current in order to achieve 100% charge within the recharge time specified by manufacturers. A lower charging current does not affect battery life, but if the power outages are frequent and the battery does not reach full charge, it leads to reduction of battery life. On the other hand higher charging current beyond 20% results in faster charging but again affects battery life. It’s very important that charging current is between 10 to 20% of battery capacity to obtain maximum battery life
  • After a discharge, charge the batteries immediately within 24 hours to prevent sulphation of the plates.
  • A normal AGM VRLA battery has a life of 250 cycles of charge/discharge cycles at 90% depth of discharge at normal operating temperature of 25-27°C. Lower depths of discharge will result in longer cycle life. Please refer to the individual battery technical specifications for exact data. Correct sizing of the battery depending on load and backup time requirement will result in optimal life and performance
  • Discharge end voltage should be more than or equal to 1.75V per cell or 10.5V for a 12V battery i.e the battery should not be discharged below 10.5V. For high rate discharges from 1C to 3C the end voltage can be reduced up to 9.6V. Refer the battery technical specification table for exact values.
  • After a discharge, charge the batteries immediately within 24 hours to prevent sulphation of the plates.

Installation Requirements

  • Check individual battery voltages and ensure open circuit voltage (OCV) is above 12.8V and all batteries being installed in a string are within ± 0.03V of each other. If the battery voltages vary beyond this, then the battery voltages have to be equalised. Failure to do so will lead to early battery failures.
  • Connect batteries in such a way that OCV’s are in descending order from the positive terminal of the UPS i.e. If the battery voltages in a 4 battery system are 12.81V, 12.83V, 12.84V & 12.81V then batteries should be connected in the following order from the positive terminal of the UPS, 12.84V, 12.83V, 12.81V, 12.81V.
  • Connect the right terminal, choose the appropriate cable, and install the connectors firmly. Use a torque wrench and terminal protection to avoid short circuit.
  • Ensure batteries are placed on a rack insulated from the ground. Use rubber or wooden strips under the rack legs. If batteries are placed on the ground directly, ensure it’s placed on a rubber mat or wooden slab or any insulated material to prevent grounding.
  • Use battery in a well-ventilated room/location
  • Check for proper torque at terminal bolt connections.

Handling Used Batteries

  • It is the responsibility of the user to ensure that used batteries are properly disposed by returning them to the dealer/manufacturer/authorised battery recycler.
  • Do not discard the battery in trash or give away or sell to an unauthorised person.
  • Please note the violations of these guidelines may lead to legal action/prosecution by the government authorities.

Battery Storage

  • Batteries should be stored in a fully charged state at a recommended temperature of 10°C  to 25°C in a dry area and in upright position.
  • Stacking should be done as per the stacking quantity depicted on the carton.
  • Batteries lose charge during storage and hence should be given a fresh charge at least once every six months.
  • Battery should not be stored near an area of high generation or exposed to direct sunlight.

Pre-shipment checks

  • It’s recommended that the Open circuit voltages (OCV) of the battery are checked prior to shipment. In case the OCV is below 2.14V per cell or 12.8V for a 12V monoblock, it should be charged prior to shipment so that it reaches the customer site fully charged.
  • Check external condition of carbon. If any damage is visible, open the carbon and check battery for any damages, cracks, or visible signs of any acid leakage etc.
  • If the batteries are to be connected in a string to the same device, ensure batteries are from same batch.

Installation and Connection

  • Room has to be well ventilated. Installation in areas without ventilation is extremely dangerous since hydrogen gas is emitted during charging and is highly inflammable. If in an air conditioned room, there should be an air exchange at least once every 4 hours. If installed in a cubicle or enclosure, it should have louvers or holes for ventilation.
  • Unpack batteries and check for any damage, breakage, or leakage. Check for even hairline cracks. It’s extremely dangerous to install damaged batteries – it can lead to fires and explosions. Check if accessories like nuts and bolts are present in carton.
  • If the number of batteries are greater than two and is to be connected in a string, the OCV of all batteries should be in range of ± 0.03V of each other. In case it is beyond ± 0.03V, then the process of “Battery Charge Equalisation” to be followed.
  • Battery rack should be insulated from the ground by placing rubber strips/PVC sheets/wooden blocks or use any insulating material. Never place batteries on the ground. If rack is not available, place the batteries on a rubber sheet or wooden board or any insulating material. Batteries placed on a rack, that is not insulated or placed directly on the ground will discharge quickly due to grounding.
  • Batteries on the rack should be placed at least 10mm apart. Rack should be positioned in such a way that both sides of rack are accessible for maintenance purpose. Rack should not be near any heat source.
  • Size and cross section of the inter battery connecting links should be exactly same length and thickness and should have the required current carrying capacity.
  • All nuts and bolts should be tightened uniformly preferably with a torque wrench. Apply petroleum jelly to the terminals to prevent corrosion and improve conductance.
  • Check charging current of the UPS/Charger/device. It should be at least 10% of battery rating on a single string.
  • Avoid connecting batteries in parallel strings. If at all parallel strings have to be used, then a maximum of 4 strings can be connected in subject to following conditions:* Batteries should be of same Ah capacity and from same manufacturing batch.* DC power supply for charging to each string should be separate.* Cable length/cross section to be uniform across all strings.* Use torque wrench compulsory to get uniform tightening of the bolts. Check the manufacturer’s specification sheet for torque values.

Charging Instructions

For standby use (Trickle charge or float charge )
  • Charge the battery at a constant voltage of 2.275V/Cell (27°C). When charging at an ambient temperature of 5°C or below or 35°C or above, it is necessary to adjust the charge voltage in relation to the temperature. The temperature coefficient should be ± 4mV/°C cell (+ if temperature is lower and – if temperature is higher).
  • Initial charge current should be 0.20CA (where C is the nominal capacity value and A is amperes) or less.
  • Charge the battery as an ambient temperature from 5°C to 35°C to prevent any adverse effects on its effective life.
For cyclic use
  • Maintain a constant voltage charge at a set voltage of 2.35V to 2.40V/Cell (27°C). In case of temperature variations, set the voltage as per the table.
  • The initial charge current should be 0.20CA or less.
  • To avoid overcharging, when charging is complete, charging to be stopped by using a timer or the constant voltage to be dropped to 2.275V / cell (27°C).
  • It is recommended that the battery is charged at an ambient temperature between 5°C and 35°C to prevent any adverse effects on its effective life.

Discharging Instructions

  • The continuous discharge and maximum discharge current should not exceed the values of specification.
  • Repeated excessive discharging will shorten the battery life.
  • After discharging, immediately recharge the battery. Never leave it in discharged state. The capacity to hold charge will be affected if the battery is left discharged for a long period.


  • Measure the total voltage of the batteries during float charge (or trickle charge). If the charging equipment provides an incorrect reading, be sure to investigate the reason behind any deviation from the specified voltage range.
  • Check the batteries for any sign of irregularities in appearance or damage such as a crack or deformation, or if electrolyte leak is found on the case cover etc. The batteries must be replaced with a new one. Also, clean the batteries if these are found to be dirty due to dirt and dust.


  • All lead acid batteries have to be recycled safely. Return the batteries to an approved recycler. Never throw the batteries away.
  • While designing the product, the battery is made easily removable and accessible in order to make its replacement/recycling or disposal easy for the customer.

Other Precautions

  • When cleaning the batteries, use soft cloth only. Use sodium bicarbonate to neutralise the surface. Do not clean the batteries using clothes that contain organic solvents or oil. Also, contact with soft polyvinyl chloride and the like must be avoided.
  • Do not short the battery.
  • Do not attempt to disassemble the batteries. Avoid contact with sulphuric acid leaked from the broken batteries. If eyes come in contact with sulphuric acid, wash it with plenty of clean water and consult a physician immediately.
  • Never dispose the batteries in fire.
