Maintenance-free lead acid battery: No Free Acid Explosion-Proof High-strength ABS plastic shell 3 years guarantee lead acid battery1. Extra long duration time at low rate current discharge

   These batteries are specially designed for low rate current dicharge. As you know, the battery is used as backup power supply when city power fails. The equipments using these batteries are low power machine and the working current is quite small. But the battery should not stop providing power to the machine until the recovery of the city electricity. Therefore, the battery should enough long time under the small working current intead of high current discharge but short duration time like Uninteruptied power supply used on computer system.

2. Excellent recover ability from deep discharge

   You also know, lead acid battery should not be completely used out(we call this DEEP DISCHARGE). Otherwise, it is difficult to recharge the battery or the battery can not completely recover even it can be recharged. As the description in caluse #1, the battery may often used out before the city electricity come back. Therefore, the battery used in Kitchen appliance should have a better recover ability from deep discharge(we called USED OUT above). We add some special ingredient when the battery plates(the most important components in battery) are made and such a special ingredient make the battery much better in recovery ability from deep discharge.

3. As long as 5 years backup( floating charging status) service life

   Of course, nobody would like to replace the battery from time to time. It is complicated and money using. Normally, lead battery has 3 years service life but our battery has at least 5 years and some time may be longer. I believe the users will be quite happy with this feature.

4. Deep discharge ability under low temperature

   Lead battery working duration time is seriously shortened if the abient temperature is low. Sometime, the low temperature shorten the duration time by 20-30% depending on the actual temperature. But this shortage can be improved through the production craft of the battery. And our battery duration time will not decrease more than 20% under a low temperature place.
