1. After the liquid level drops, should I add distilled water or electrolyte?
Distilled water should be added when the liquid level drops, and no electrolyte should be added. Because the liquid level drops mostly due to evaporation of water and electrolysis of water at the end of charging. If the electrolyte is added, the specific gravity will increase and the service life of the battery will be affected. However, if the liquid level is lowered due to the leakage of the electrolyte caused by the crack in the outer tank, the electrolyte should be added after the repair of the joint.
2. How high should the electrolyte level be suitable?
The electrolyte liquid level should be 10-15 mm higher than the electrode plate. If the liquid level is too high, it will easily overflow and corrode the surrounding parts. However, when the plate is too low, the upper plate is easily exposed, which not only reduces the battery capacity, but also exposes the exposed plate to be quickly vulcanized. The plastic tank battery has an electrolyte height mark on the outer tank. Generally, the electrolyte liquid level should be flush with the "max or U" line.
3. What should I do after the battery is frozen?
The reason for battery icing is generally:
(1) The battery has a low specific gravity when it leaves the factory. The electrolyte reaches a freezing point when used in cold regions;
(2) After the battery is over-discharged, the specific gravity of the electrolyte drops more, but it is not charged in time;
(3) The electrolyte liquid level is too low. After adding distilled water, the engine is not operated for a certain period of time, so that the upper and lower specific gravity of the electrolyte are inconsistent, and stratification occurs.
General treatment method:
The icy battery should be moved to a warm room to let it melt slowly; then charge the battery with 1/3 of the specified charging current, continuously observe the cell voltage and electrolyte temperature, and the specific gravity of the electrolyte should reach 1.28 g after charging. /cm3, if not in compliance, adjust with distilled water or sulfuric acid with a specific gravity of 1.40 g/cm3.
4. How to prevent plate vulcanization?
(1) Do not leave the semi-discharged storage tank for a long time, so that the battery should always be charged.
(2) The liquid level of the electro-hydraulic solution should not be too low. The liquid level must be 10-15 mm above the plate. After the addition, the liquid should be replenished.
(3) Do not over discharge the battery.
5, the battery does not charge or charge after charging?
(1) The charging method is wrong, and a battery-specific charger is required;
(2) The charging current is small or the charging time is short;
(3) Poor contact of the clip during charging;
(4) Sulfation of the battery plate;
(5) The wiring clip is in poor contact with the battery, and the vehicle line or other accessories are faulty;
(6) The battery has a short circuit or open circuit failure;
6. Maintenance of pre-sale, in-sale and after-sale vehicle batteries
Pre-sale, sale battery replenishment:
Wrong method:
(1) The battery is recharged when the battery is completely unable to start the vehicle;
(2) Directly start the vehicle, and the neutral gear will naturally rotate for ten minutes or several hours and then stop;
*The correct method:
(1) Recharge the battery at least once a month;
(2) Remove the battery and charge it with a dedicated charger according to the specified charging requirements.
Maintenance of after-sales battery:
(1) The battery must be kept clean at all times.
(2) Do not allow any foreign matter to fall into the battery.
(3) The contact devices between the individual cells and the connection to the wires must be completely reliable.
(4) Regularly inspect and wipe the vent to prevent clogging of the battery seal cover.
(5) Always check the electrolyte level and do not let the plates and separators out of the liquid level.
(6) When the addition fluid is maintained, the electrolyte must be adjusted to the normal density (1.28g/cm3) when the battery is terminated.
(7) When the battery is low, it is strictly forbidden to get on the train.
(8) The temperature of the electrolyte shall not exceed the value specified in the specification, which is generally 45 °C.
(9) Regularly perform balanced replenishment (overcharge) according to the instructions.
(10) If the battery is left on for a long period of time, in order to avoid excessive self-discharge and severe sulfation, it should be replenished monthly.
(11) Open flame is strictly prohibited during battery use and charging.
(12) Apply butter regularly to the terminals.
(13) It is strictly forbidden to adjust or twist the wiring clamp when the vehicle rotates to prevent sparks and the battery from exploding.
Galvanized + Painted screw pin anchor shackles are priced to move. Made of galvanized carbon steel, the anchor shackle is a tough and durable accessory for nylon slings, as well as polyester slings. Paired with a lifting sling and tow straps, they help protect the eyes of your sling from wear and tear on clevis hooks. They come in various sizes and strengths ranging from 3/16" - 2-1/2" and 1/3 Ton - 55 Ton. This clevis can be used in many applications such as industrial, agricultural and marine applications. Shackle color may vary.
