2. Common symptoms of battery water shortage
According to feedback from netizens and suggestions from experts, battery water shortage usually manifests as the following phenomena:
| Symptoms | Possible reasons |
|---|---|
| Motor is weak when starting | Insufficient electrolyte causes voltage drop |
| Battery case is hot | Internal dryness causes overheating |
| The battery is still low after charging | Increased plate vulcanization |
3. Solution to battery shortage
Step 1: Check battery water level
Open the battery cover (tools required) and observe whether the internal plates are exposed. Normal water level should cover the plate by 5-10mm.
Step 2: Add distilled water (not tap water!)

| Tools/Materials | Things to note |
|---|---|
| Medical syringe (with graduation) | Precisely control the amount of water added |
| rubber gloves | Prevent acid from corroding skin |
Step 3: Charging Recovery
Add water and let it sit for 30 minutes.Low voltage slow charging (12V/2A)Charging for 8-10 hours activates battery performance.
4. Effective tips tested by netizens
1.High temperature warning:When parking, avoid direct sunlight to reduce water evaporation.
2.Regular inspection:Check the water level every 3 months, especially in older batteries.
3.Emergency plan:If there is a temporary water shortage, purified water can be used as a substitute (emergency only).
5. Professional advice and risk warnings
1. There is no need to add water to the maintenance-free battery. Forcible operation will damage the sealing structure.
2. If the battery has been used for more than 3 years, it is recommended to replace it directly.
