Q: What kind of product quality your factory offer?

A: We provide the most competitive products at the highest quality. (100% cell sorting test under inner resistance ≦2mΩ, voltage differ ≦ 2mV,100% EOL test, 100 % aging, 100% final product testing) .

Q: Can we print our logo on products?

A: We can provide one to one customized OEM with a MOQ demand.

Q: What is the validity of the quotation?

A: Due to the raw material price fluctuation, the quotation validity is 10 days.

Q:What are the technical parameters of the battery?: The main performance parameters of the battery are the following: model; voltage; battery capacity; battery type, such as lead-acid batteries, alkaline batteries, lithium batteries, solar cells, fuel cells.

Q:Maintenance-free battery how to detect it?: Check the height of the electrolyte at least once a month. There is no mark line of the battery, the electrolyte added to the plate 10-15mm can be higher; there are two red line of the battery, the electrolyte can not exceed the red line above.

Q:What kind of battery is divided into?: At present, we used the car battery is divided into three categories, namely, ordinary batteries, dry batteries and maintenance-free batteries three.

Q:Lead-acid battery how to maintain?: After passing the test, cover the exhaust cutting, pay attention to restore the filler, cover the battery cover, if the cover is glued, then glue bonding.

Q:How does the battery increase the voltage?: You can use the same battery in series, with 5 12v battery in series becomes 60v, if you need the current is relatively small, you can use DC-DC module to 12v voltage rise to 60v.

Q:How does battery activation work?: Always keep the battery surface clean. Found that the surface of dust and acid, it should be timely wipe, wipe can be wiped with soda water wipes wipe again, after rinse with water.

Q:What is a maintenanceable battery?: It also has a shock, high temperature, small size, self-discharge characteristics. Life is generally twice the ordinary battery.

Q:What are the advantages of maintenance-free batteries?: The advantage of a maintenance-free battery is that the service life is twice as long as the dry battery! And in the use of the process without maintenance! The voltage is also relatively stable.

Q:How is the capacity of the battery defined?: 100AH capacity of the battery, fully charged after the 100A current discharge can be an hour to put the power finished. 50A current is 2 hours put away! 20A is 5 hours! Of course this is the theoretical value, in fact it is impossible to have a constant current discharge.

Q:How to deal with waste batteries?: In addition to lead-acid batteries, all kinds of batteries are dissolved in sulfuric acid, and then by means of ion resin from the solution to extract a variety of metals, raw materials obtained in this way than the heat treatment method is pure, so the market price is higher, and the battery contains 95% of the various substances can be extracted.
