The ION Power Pack is a 25.2-volt removable, rechargeable lithium-ion battery pack.

To insert, slide the ION Power Pack Battery into the slot on the back of the handheld vacuum. To remove, pinch the release tab and slide the ION Power Pack battery out of the handheld vacuum.

The lights on the ION Power Pack serve multiple purposes. One purpose is to show the remaining charge in your ION Power Pack while in use. The lights will also blink and illuminate to show the status of the ION Power Pack while charging. In addition, the lights will illuminate in certain configurations to inform you of any issues with the ION Power Pack.

You can charge your ION Power Pack by using a Shark^® ION Power Pack Charger along with accessories such as the charging dock and wall mount. Please note that only Shark chargers should be used to charge an ION Power Pack. Consult your instruction book for approved models.

Your ION Power Pack should take approximately 3.5 hours to reach a full charge.

The ION Power Pack, like all lithium-ion products, will naturally decrease in capacity over time from the 100% capacity of a new battery.

Upon product registration, your purchase is recorded. Our Customer Care agents can review if your battery is under warranty.

The ION Power Pack, like all lithium-ion products, will naturally decrease in capacity over time from the 100% capacity of a new battery.

These times are based on 100% capacity:

The initial charge on the pack is approximately 30%. Fully charge the pack (3.5 hours minimum/overnight preferred) and assess battery performance.

Note that battery run time is affected by the amount of work you are performing. Vacuuming on high pile carpet while using “ION Boost” will reduce battery run time quicker than vacuuming bare floors.

If you have more than one battery, it is recommended that you use each equally in use and charging.

Your ION Power Pack may feel warm in use as air passes through the vacuum. If it feels uncomfortably warm, stop using the vacuum and allow for the battery to cool. If the battery continues to feel warm, or you see any LED indicators as outlined in your instruction book, contact Customer Service.

The charger is designed to monitor many factors of the battery. After use, batteries can get warm, a condition that is not optimal for charging. In such cases, the charger waits for the battery temperature to decrease to the optimal point before it begins charging.

The ION Power Core battery is a 28.8-volt removable, rechargeable lithium-ion battery pack.

The initial charge on the battery is approximately 30%. Before first use, discharge battery fully to condition it properly, then charge the battery completely until the charge indicator light dims. It takes approximately 2.5 hours to charge the battery completely.

Note that battery runtime is affected by how long the unit’s power is on. It is recommended to turn the vacuum off when not in use and when between cleaning jobs.

It is recommended that you leave your vacuum on the ION Charging Dock after each use to recharge the battery completely.

You do not have to wait for your battery to fully discharge before you can charge it again. It is recommended that you leave your vacuum on the ION Charging Dock after each use to recharge the battery completely. For optimal runtime, always return your vacuum to the dock after each use.

The red charging light will fade in and out. This means the vacuum is charging.

Lithium-ion batteries take approximately 6 hours to fully charge.

A full charge will last about 13 minutes if you are using a motorized attachment. Without a motorized attachment, the handheld vacuum can run longer. It is normal that battery run time gets shorter after a year. Please note that batteries are not covered under warranty.

When the red light indicator flashes for 5 seconds this means either the battery power is low or there is a jam in the unit. Clear any clogs or debris buildup.

When the handheld vacuum is charging, the red indicator light will fade in and out. When the vacuum is fully charged, the indicator light will turn green for 5 seconds, then shut off.
