Description
The SEA 50 is a battery-powered wet & dry vacuum cleaner that’s part of the AK System. This compact vacuum cleaner is completely portable and designed for cleaning around the house, garage, inside vehicles and in workshops. Powered by a 36-volt lithium-ion battery, this vacuum cleaner is cable-free for easier working and has a compact design for greater freedom of movement when working in confined spaces.
The SEA 50 comes equipped with a universal floor nozzle and crevice nozzle for taking on different cleaning tasks and a 2-piece suction tube for cleaning hard-to-reach areas. A shoulder strap is included for hands-free operation, which is ideal when you are cleaning on the move.
All the accessories can be neatly stored away on the SEA 50. The 1.8m long vacuum hose can be stored at the top of the vacuum. The universal floor nozzle and crevice nozzle slot into the side. And the 2-piece suction tubes slot into the bottom of the tool. This saves plenty of space for you when storing the SEA 50 away in your cupboard or garage.
The SEA 50 is certified for dust class “L” making it suitable for some semi-professional applications such as removing plaster or sand. The PET filter element can be used multiple times as it is easy to wash out and reuse. The battery compartment is covered too, for protection from splashed water or dust. The vacuum cleaner has a power selector switch that lets you change between 2 levels when working:
- Level 1 – standard power mode, suitable for smooth floors and extending working time by up 50%
- Level 2 – high suction power mode, suitable for cleaning stubborn dirt from all surfaces
If you need better mobility and flexible handling while vacuuming, there is a wheel cart & accessories available. You can also buy an additional set of mini nozzles, which are ideal for cleaning the smaller, difficult-to-access spots in your car or at home.
On a fully charged AK 20 battery, the SEA 50 has a working time of 16 – 27 minutes, which depends on the power mode selected.

STIHL Battery Care Guide

Why you should not charge your lithium-ion battery before storing it
Today, battery technology uses lithium-ion as standard, and these cells experience negligible levels of self-discharge. To protect cells from over-discharge, a lithium-ion battery is usually built with separate integrated fuses that can automatically switch a highly discharged battery to a rest state, so they don’t need to be fully charged before storage. In fact, lithium-ion battery life is extended if it goes into storage partly charged – that said, it’s worth remembering that cells are negatively impacted in the event of storage with a very low level of charge or if the battery is fully charged. We recommend that you store a lithium-ion battery with two lit LEDs, indicating a charge of 40-60%, to minimise ageing and self-discharge.
Proper storage of tools with an integrated battery
A power tool with an integrated battery, such as the FSA 45 grass trimmer, needs to be treated differently from other cordless tools, as you cannot remove the battery for storage purposes. Battery storage preparation for these tools is simple:
- Switch off the power tool and pull out the activation key.
- Use a damp cloth to clean any dirt or soil off the power tool before it goes into storage.
- Keep the power tool in a dry, secure place.
Store the power tool at low, frost-free temperatures. Avoid storage in direct sunlight and damp conditions. Further information on the storage temperature for your power tool is available in the instruction manual. For safety, we recommend storing the activation key separately from the cordless power tool.
When is the best time to charge the integrated lithium-ion battery again?
If you are using your cordless power tool with an integrated battery after a lengthy storage period, charge it just before you use it. This safeguards the capacity and has a positive effect on the service life. The battery will only charge at temperatures above 5°C; the charger monitors the battery temperature and prevents charging if the temperature is too low or too high.
Keep your lithium-ion battery protected
- Remove the battery from your cordless power tool before storage. Check the charge level and make sure that 2 LEDs are lit on your battery. If required, use a damp cloth to clean dirt and soil off the battery.
- Store the battery in a dry place and out of direct sunlight, in a closed box, for example.
- Temperature requirements: it’s best to store batteries at a temperature between -10°C and 50°C – dry basements, garages, or a well-insulated shed, for example.
- Store your lithium-ion batteries in a secure place, and place them safely out of the reach of children.
- Store the charger separately from the battery, at a temperature between 5°C and 40°C.
- Further information on the storage temperature for your power tool is available in the instruction manual.
Is it dangerous to charge a battery for too long?
It’s normal for a battery to become hot when charging, and it is not a cause for concern. High-tech Li-ion batteries carry a very low fire risk, thanks partly to the integrated battery management system, which ensures that when a battery reaches its full charging capacity, the lithium-ion battery charging process is stopped and the current switched off. This prevents overcharging and the associated heat build-up.
Protect your battery against cold weather and frost
A Li-ion battery may also be damaged if temperatures are too low; whereas particles are accelerated when hot, in cold conditions, the process slows down dramatically, so a frozen battery may be impossible to charge. We recommend you do not store your battery and cordless power tool outdoors during the winter, and always ensurea moderate ambient temperature when charging or storing, in a basement or garage, for example.
Worth noting!
All STIHL batteries are supplied to dealers with a factory default charge level of 30%. Before first use, the battery should be charged to 80-100%.
