When you overcharge your Dyson V7, you’re essentially reducing the battery’s lifespan. Overcharging causes the lithium ions to become trapped, leading to a decrease in the battery’s capacity and overall performance. This means your vacuum might not hold its charge as well, or might not last as long as it used to.
Battery Swelling and Safety Risks
In extreme cases of overcharging, lithium-ion batteries can swell, which can lead to a range of safety issues:
- Fire Hazards**: A swollen battery can ignite, causing a fire that can spread quickly.
- Electrical Shock**: A damaged battery can also lead to electrical shock, posing a risk to your safety.
How to Avoid Overcharging Your Dyson V7
