Advantages |
|
 |
Extra heavy duty thicker plates as per exclusive Exide design ensuring durability, resistance to corrosion and inbuilt margins for high ambient temperature. |
|
Suitoble for long and frequent powercuts with quick recharge adoptability |
|
Built with PE pocket type seperator bonded with glass mat for extra supporI to active material, making the battery more suitable for deep cycle application. |
|
Substantial savings in floor area |
|
These is high acid volume per ampere hour ensuring low maintenance characteristics. |
|
Resistance to abuse |

| Initial Charging Instructions |
|
| 1. |
Filling in Specific Gravity |
1.220+/ - 0.005 at 27º C |
| 2. |
Rest Period |
12 hrs |
| 3. |
Minimum Ah output |
525Ah for IF1800 and 615Ah for IF2000 |
| 4. |
In order to reduce the charging time, the following routine may be adopted. For IF1800, the initial charging current may be 18A upto 2.36 vpc followed by 9A upto 2.75 vpc. For IF2000, the initial charging current may be 21A upto 2.36 vpc followed by 10.5A upto 2.75 vpc.
However in both cases, minimum Ah input to be given. Under no circumstances, battery temperature should not exceed 500C. In case the temperature exceeds 500C, adequate rest to be given till the electrolyte temperature comes to ambient temperature and charging to be continued. |
| 5. |
Conditions of fully charged |
|
3 consecutive hourly readings of specific gravity and voltage become constant |
|
Top of charge voltage will be around 16.2V - 16.5V |
|
All cells should gas freely |
|
Minimum Ah has been given |
|
| 6. |
Specified gravity of fully charged condition |
1.250 +/ - 0.005 at 27ºC |
|
Normal Recharging Instructions |
|
| Recharging throughl Inverter at constant potential mode of 14.4V with limited current as specified. After battery potential reaches 14.4V, the battery should continue in trickle 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 centres. |
