|
|
Very long life |
|
Can withstand overcharge better |
|
User friendly |
|
Occupies less floor space, totally new look |
|
Acid volume per ampere hour is 30% more than that of ordinary tubular batteries. It acts as a coolant and also ensures very low maintenance |
|
Less pollution, environment friendly |
|
Suited for use in areas of frequent power cuts (800 to 1000 cycles of deep discharge as against 300/400 cycles of other batteries) |
|
Ensures consistent quality |
|
| Application |
|
| The next generation Tubular battery designed specially for withstand long and frequent powercuts. It is the ultimate Inverter battery. |

| 2. |
Rest Period |
10-12 hrs |

In order to reduce the charging time, the following routine may be adopted. For IT400, the initial charging current may be 12A upto 2.36vpc followed By 6A upto 2.75 vpc. For IT500, the initial charging current may be 14.4A upto 2.36vpc followed By 7.2A upto 2.75 vpc. For IT550, the initial charging current may be 16A upto 2.36vpc followed By 8A upto 2.75 vpc. For IT 650 , the initial charging current may be 19.2A Up to 2.36vpc followed by 9.6A upto 2.75vpc.
However in both cases, minimum Ah to be given. Under the circumstances, Battery temperature should not exceed 50ºC. In case the temperature exceeds 50ºC Adequate rest to be given till the electrolyte temp. comes to ambient temp. 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 e 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 27º |
|
Normal Recharging Instruction |
|
| Recharging through Inverter at constant potential mode of 14.4V with limited current as specified. After battery potential matches 14.4V, the battery should continue in trickle charge made at constant potential of 13.8V. |
