It is not possible to add repair fluid to the dry battery, because the electrolyte inside the dry battery is a jelly-like substance, which cannot be maintained by adding repair fluid. And the dry battery itself is a maintenance-free battery, basically a completely sealed structure, so in the daily use process, this type of battery does not require any maintenance. If there is damage, you can directly replace the new battery.
Moreover, the main characteristics of dry batteries are high performance, long life and maintenance-free. The electrolyte consumption in the process of use is very small, so the service life of dry batteries is at least twice that of ordinary batteries.
When the dry battery is damaged, it will basically reach the service life of the battery. At this time, it is best to replace a new battery, and as mentioned above, the entire battery of the dry battery is sealed, and there is no place to add repair fluid.
As for the small hole we see on some dry batteries, it is actually used to vent it. Once the repair fluid is added from here, it will affect the internal structure of the battery and even cause damage to the whole.
Most dry batteries actually have a cover, and there is a hole-shaped liquid cover in the cover, which can be used to judge whether the dry battery is in an abnormal state according to the color change of the liquid. If the color seen in the observation hole is light yellow, it means that the dry battery may be low in power and needs to be charged in time. If it turns black, it needs to be replaced with a new battery.
