1. How long is the warranty for your battery?

A: We provide 3 ~ 5 years different warranty.

2. How about the delivery time?

A: 7-15 working days for bulk order after your deposit is confirmed.

3. Can you print my logo on the batteries?

A: Yes, OEM is accepted.

4. Is the battery capacity at 10HR or 20HR?

A: Our battery is at 10HR.

5. What certificate you have to guarantee quality?

A: CE,UL,ROHS,IEC61427,MSDS

6. What is the storage life of your battery?
A: Batteries are best stored at 20℃. When batteries are stored in areas where the ambient temperature varies, self-discharge can be greatly increased. Check the batteries every three months or so and charge if necessary.

7. What is the package for exporting?

A: Single battery will be packed in carton box, and boxes in poly-wood case.

8. Do your battery has legal certificate to ship by Sea or Air?

A: All of our batteries owe Certification for Transport of Chemical Goods by Air and Sea, which are certificated by SICIT with CNAS, China Customs strengthens management of illegal traffic.

9. If battery damage,how will you solve the problem?

A: If there is problem happened , we will gather all the picture and according to your using condition to find out what cause this problem. If it is quality problem, we will replace you the new one in the next shipment.

10.  What determines the life of VRLA battery?
A: Sealed lead acid battery life is determined by many factors, including temperature, depth and rate of discharge, and the number of charges and discharges(called cycles).

11. Does over-discharging damage batteries?
A: Over-discharging is a problem which originates from insufficient battery capacity causing the batteries to be overworked. Discharges deeper than 50% significantly shorten the Cycle Life of a battery without increasing the usable depth of cycle. Infrequent or inadequate recharging can also cause over discharging symptoms called SULFATION. Despite that charging equipment is regulating back properly, over discharging symptoms are displayed as loss of battery capacity and lower than normal specific gravity. Sulfate occurs when sulfur from the electrolyte combines with the lead on the plates and forms lead-sulfate. Once this condition becomes occurs, marine battery chargers will not remove the hardened sulfate. Sulfate can usually be removed by a proper desulfation or equalization charge with external manual battery chargers. To accomplish this task, the flooded plate batteries must be charged at 6 to 10 amps. at 2.4 to 2.5 volts per cell until all cells are gassing freely and their specific gravity returns to their full charge concentration. Sealed AGM batteries should be brought to 2.35 volts per cell and then discharged to 1.75 volts per cell and then this process must be repeated until the capacity returns to the battery. Gel batteries may not recover. In most cases, the battery may be returned to complete its service life.

12. How to keep the consistency of the battery pack?

A: Though there is a strict battery selection procedure, after a certain period usage, the non-homogeneity will appear more and more obviously. Meanwhile, charging equipment can’t choose and recognize the weak battery out, so it is user who can take control of how to keep the equilibrium of battery capacity. User would better test the OCV of every battery regularly or irregularly in the middle and later period of battery pack usage and recharge the battery of lower voltage separately, in order to make the voltage and capacity as the same as other batteries, that decrease the difference between the batteries.
