Ambrane India — Better runtime once I maintained it well

I bought the MiniVac 02 mainly for quick car cleaning, but after a few uses I noticed the battery life started to drop faster than before. It used to last a good while on a single charge, but later I barely got through one small round. I contacted customer support because I was not sure if the battery was degrading. They suggested a full charge cycle and also advised against storing it with dust inside for long. After doing a full drain and recharge and keeping it clean between uses, the battery runtime improved again. It does not last as long as day one, but it feels reliable for quick cleanup now.
