Select the item you have received – we’ll show you the right tips to ensure it lasts a long time and performs at its best.
A rechargeable battery for vacuum cleaners, laptops, cameras, tools, robotic lawnmowers and more
Charge the battery fully once before using it for the first time. There is no need for a lengthy ‘conditioning’ process with modern lithium-ion cells.
Don’t let the battery run completely flat. Frequent recharging is gentler on lithium-ion batteries than constant deep discharging.
Heat is the biggest enemy. Do not charge or store the device in direct sunlight or in a hot car.
Going to be away for a while? Store it half-full, in a cool, dry place – neither completely full nor completely empty.
A charger, power supply or docking station.
The voltage, current and plug are compatible with your model. When buying replacement parts, ensure they have the same specifications.
Leave the charger in an open space, do not cover it and do not operate it on a soft surface.
It is not necessary to leave it running continuously. Unplug the charger afterwards to save electricity.
Rechargeable batteries – AA, AAA & Co.
NiMH batteries are supplied partially charged. Charging them fully once restores their full capacity.
Always charge and replace all the cells in a device at the same time – do not mix old and new ones.
Used batteries should be placed in the collection box; never put them in the general household waste.
Cables, adaptors & connection technology.
Roll it up loosely rather than winding it tightly around appliances – that keeps the wires in good condition for longer.
Keep plugs and contacts dry and free from dust to ensure a secure connection.
Check that the plug type and standard match the appliance, and it’ll fit.
Filters, lids, battery handles & camera chargers.
Accessories such as filters, lids or handles are model-specific.
With the dual charger, you can charge two batteries at the same time.
Protects contacts and the display from moisture.
