What are the categories of Panasonic batteries?
Recently, when many users buy Panasonic batteries, they have such questions as why there are so many types of batteries. Such as: ordinary batteries, dry-charge batteries and maintenance-free batteries. Today Xiaobian talks about the classification of Panasonic batteries.
1. General storage battery
The plates of ordinary batteries are composed of oxides of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. Its main advantages are voltage stability and low price, while its disadvantages are low specific energy (i.e. the energy stored in each kilogram of battery), short service life and frequent daily maintenance.
2. Dry-Charged Batteries
Its full name is dry charged lead-acid batteries. Its main feature is that the negative plate has a high energy storage capacity. Under completely dry condition, it can save the electricity in two years. When used, only adding electrolyte can be used in 20-30 minutes.
3. Maintenance-free batteries
Maintenance-free batteries consume very little electrolyte due to their own structural advantages, and there is no need to supplement distilled water during their service life. It also has the characteristics of shock resistance, high temperature resistance, small volume and small self-discharge. Usually the service life is twice as long as that of ordinary batteries. There are also two kinds of maintenance-free batteries on the market: the first one does not need to be maintained after one-time adding electrolyte when purchasing (adding supplementary liquid); the other is that the batteries themselves have been added electrolyte and sealed when they leave the factory, so users can not add supplementary liquid at all.
Common shortcomings of Panasonic battery
After a long period of application, the battery of the best quality will also have various shortcomings. Although the quality of Panasonic batteries is at the top level in the industry, it can not prevent this problem. When there are shortcomings in the batteries, we can determine the reasons for their shortcomings through testing, and then repair them. Then Panasonic batteries will give us some common shortcomings of Panasonic batteries. Points and solutions are expected to help you.
Satisfactorily electrified or using superb batteries, after 1 - 2 days there will be no electricity, the headlamp will not turn on. Press the electric horn to weaken or even make a small noise dynamically. It can be regarded as self-discharging battery. There are two main reasons: one is that the battery separator is broken down or damaged, and impurities such as metal powder are mixed into the electrolyte. Or Panasonic battery tank bottom accumulated too many foreign bodies, forming a short circuit inside the battery; Second, the battery shell is too dirty or overflowing electrolyte is too much in the unswerving, forming a short circuit between the cover and the pile head.
The first thing to check is whether the battery's appearance is clear. Does the electrolyte overflow to form a conductive layer? Then check whether there is bad contact between the pile head and the conductor, or bad iron overlap, the diagnosis method is: disconnect the power switch, remove the negative battery wiring, scratch it on the pole pile, if there is spark attack at this time, clarify that there is a short circuit inside the battery, it should be removed and repaired.
