Initial Charging Instructions:
Filling in Specific Gravity 1.220±0.005 at 27 °C  

In case the temperature exceeds 50°C, adequate rest to be given till the electrolyte temperature comes to ambient temp. and charging to be continued

Rest period 4 - 6 Hrs.

In case the temperature exceeds 50°C, adequate rest to be given till the electrolyte temperature comes to ambient temp. and charging to be continued
Minimum Ah input as per above chart. Condition of fully charged –
In order to reduce the charging time, the initial charging current would be as specified till 2.36 Volts/Cell followed by finishing current as specified till 2.75 Volts/Cell.  
  3 consecutive hourly readings of specific gravity and voltage become constan
  Top of charge voltage will be around 16.2V – 16.5V
  All cells should gas freely.
  Minimum Ah has been given
However in both cases, Minimum Ah input to be given. Under no circumstances, battery temperature should exceed 50°C.   Specific gravity at fully charged condition – 1.250±0.005 at 27°C
 

Normal Recharging Instructions

Battery should be re-charged through an Inverter at constant potential mode of 14.4V with limited current as specified. After battery potential reaches 14.4V, the battery should continue in float charge mode at constant potential of 13.8V.
 

Statutory Notice

All batteries contain lead, which is harmful for humans and environment. As per statutory requirements, the used battery must be returned to the authorized dealer, manufacturer or at the designated collection centers.
