A: Yes, it is avaliable.

Q: What is your payment terms?
A: Sample payment through Paypal or Western Union, and mass order by T/T or L/C.

Q: How to repair the battery?: Pry open the adhesive or heat-sealed battery cover, reveal the maintenance-free battery rubber exhaust valve, carefully remove the exhaust valve, save, observe the battery internal situation. Add 0.1% to 0.5% of the electrolyte to the battery, just to the battery above the flow of electrolyte. At the same time, check whether the black impurities, if there are obvious black turbid impurities, indicating that the battery plate has been significantly softened, the possibility of battery repair is relatively small. If there is no black muddy impurities, need to wait 4 hours later, the water fully into the battery. If it is only because the deactivation time is long and cause the battery capacity to decline, do not need to carry out this step operation, should go directly to step 3 pre-charge.

Q: What are the technical parameters of the battery?: Battery capacity is defined as ∫ t0tdt, theoretically t can be infinite, but in fact when the battery discharge is lower than the termination voltage continues to discharge, which may damage the battery, so t value is limited, the battery industry, in hours (h) Battery sustainable discharge time, feel the C24, C20, C10, C8, C3, C1 and other nominal capacity value.

Q: How to determine the battery is good or bad?: If less than 9V but the pointer is in a certain value does not move that the battery is in a state of loss, need to add charge.

Q: What are the hazards of battery over discharge?: When the battery discharge current is large, the heat will become more obvious, there will be serious heat generated when the battery deformation, when the concentration of lead sulfate is particularly large, will form a larger crystal particles, that lead to the battery Internal irreversible sulfation.

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 should the battery be well maintained?: Battery Pile The battery pile head is part of the battery connected to the vehicle. If the corrosion or poor connection occurs, the battery will work poorly. The owner can check whether there is a white powder near the pile head, which is the sign of the pile head corrosion. If the white powder is more, you can use boiling water to burn it off, and then its anti-corrosion treatment, in the pile head smear some grease or preservatives can, but should not be too much to apply, so as not to affect the use.

Q: What kind of battery is divided into?: Maintenance-free battery due to its own structure on the advantages of electrolyte consumption is very small, in the life of the basic need not add distilled water. It also has a shock, high temperature, small size, self-discharge characteristics of the general life is generally ordinary Twice the battery. There are two kinds of maintenance-free batteries on the market.

Q: How does the battery increase the voltage?: With the same battery pack in series; if the required current is relatively small, you can use DC-DC module.

Q: Battery 200ah / 104 what does that mean?: This should be refers to 2V200AH battery 104, power with the 220V.

Q: Lead-acid battery how to maintain?: Open the rubber cap, exposing the exhaust raft, you can see the battery inside, some of the battery exhaust cutting can be unscrewed.
