My battery won’t charge. the bars all light up for a few seconds when first plugged in, then no bars are lit up anymore while it’s charging on the dock. Once it’s turned on, only one bar lights up and the vacuum lasts a very short time and won’t work if boost is pressed. I’ve checked the connections and had it charging for multiple days and it only charges up to one bar still when turned on and no bars flashing or lit when charging. What is wrong with my VAX slim vac pro VSV21W

The battery charging issue with the Vax Slim Vac Pro VSV21W, where it only charges to one bar and does not function properly, could be caused by one or more of the following:
1. Battery Overheating: If the battery is hot, the charger will not start charging until it cools down. Ensure the vacuum is left to cool before attempting to recharge.
2. Battery Degradation or Fault: The battery may be faulty or degraded, especially if it consistently fails to charge beyond one bar. Lithium-ion batteries can lose capacity over time.
3. Charger Issues: A damaged or incorrect charger may not supply the correct voltage or current. Use only the specified E-TEK Model ZD012A265050AU charger.
4. Power and Charge Indicator: If only one light flashes and the vacuum does not function, it means the battery is low or not charging properly. If all three lights flash, the battery is depleted and must be recharged before use.
5. Incorrect Charging Environment: Charging in a wet or unsuitable area or using a damaged cord may prevent proper charging.
Check all components, allow the battery to cool, and ensure you're using the correct charger. If the issue persists, the battery or charger may need replacement.

The battery charging issue with your Vax Pro vacuum, where it only shows one bar and lasts a short time, could be due to one or more of the following reasons:
1. Overheating: If the battery is hot, it will not charge until it cools down. Charging begins automatically once the battery cools.
2. End-of-life battery: Vax batteries may stop holding charge effectively over time. If the battery only lasts a short time and shows limited charge, it may be degraded and need replacement.
3. Faulty battery: Some users report receiving faulty batteries that stop charging soon after use. If this is the case, a replacement may be needed.
4. Incorrect charging: Ensure the charger is functioning properly and the battery is fully seated in the charger.
5. Usage on high power: Using the vacuum on maximum suction reduces battery life to around 25–30 minutes, which may appear short if you're expecting longer runtime.
Check the battery temperature, verify charger function, and consider battery age or fault as likely causes.
