This guide outlines all processes related to battery safety, including reporting damaged batteries or chargers, safely storing batteries in the cabinet, understanding the cabinet's alarm system, and ensuring battery safety in the event of a bike accident.

It serves as a vital resource for Ops Associate Plus (OA+), Shift Leads (SL), and Hub Managers (HM) to safeguard the workforce, prevent fires, and maintain compliance with safety regulations.

In this guide, you'll find:

The 4 pillars of safe battery handling at the hub.
What to do in an emergency, and how to report damaged batteries or chargers.
Storage limits, battery weights, and visual examples of correct vs. incorrect storage.

The 4 Pillars of Battery Safety

Every team member working with batteries must follow these four pillars at all times.

🔍 1. General Safety Inspect regularly: check batteries for damage, swelling, or leaks before use. Do not use damaged batteries. Use approved chargers: always use the manufacturer-approved charger to avoid overcharging or overheating. Avoid overloading: do not charge multiple batteries simultaneously if it exceeds the electrical load capacity.	📦 2. Storage Temperature control: store batteries inside a NEN3134 certified battery cabinet. Ideal temperature: 15°C to 25°C. Placement: store on stable, non-flammable surfaces. Never stack batteries or chargers. Keep heavy batteries on lower shelves. Avoid water exposure: do not store batteries near water or in humid environments.
🔌 3. Charging Monitor charging: charge in a well-ventilated area. Do not leave charging batteries unattended. Follow capacity limits: 1 bike battery = 2 Amperes to charge. Never exceed the maximum shelf or cabinet electrical capacity. Use fire-resistant cabinets: charge and store in cabinets with fire-resistant ratings (e.g. 90 minutes).	✋ 4. Handling Safe transportation: use a padded container to transport batteries securely and avoid impacts or punctures. Handle with care: do not drop, pierce, or apply pressure to batteries. Label defective batteries: clearly mark damaged batteries and isolate them in a designated area for proper disposal or repairs.

Emergency Procedures

🚨 Overheating or fire

Leave the battery inside the battery cabinet.
Evacuate the building.
Call 112 for assistance.
Do not attempt to put out a battery fire with an extinguisher.

Disposal: dispose of batteries only through a certified agent.

Key Reminders

Always keep batteries and chargers away from flammable materials.
Train all staff on proper battery handling and emergency response procedures.
Regularly inspect and maintain battery cabinets and charging equipment.

How to Report Battery and Charger Damage

Hubs report battery and charger damage through the Report damage feature in HubOne. Open the affected fleet item in HubOne, select Report damage, choose the correct damage type, and add a photo if needed.

Important

This replaces the previous Zendesk ticket flow. Hubs should no longer raise Submit a Request → Fleet → Battery tickets — use HubOne's Report damage feature instead.

Alarm System in the Cabinet

Your cabinet is equipped with a smoke detector and an alarm system connected to Securitas. If the alarm is triggered, Securitas will contact the Hub Manager, City Manager, or Safety Manager for verification.

If no imminent fire is detected, inspect the cabinet and contact the QESH Manager (Ozan) if you have any questions.

Bike Accidents and Battery Safety

In the event of a serious bike accident involving one of your Riders:

🔍 1. Inspect the Battery

Check the battery for any visible dents or damage.
If the battery is damaged, label it as such and follow the process in How to Report Battery and Charger Damage.

📦 2. Store Safely

Place the damaged battery on the bottom shelf of the cabinet.
Do not attempt to charge a damaged battery.

Closing for the Day

Before closing the hub for the night:

Ensure all batteries are safely stored inside the cabinet.
Verify that the cabinet doors are securely closed.

Visual Examples of Battery Storage

Use these examples as a quick visual reference for what good and bad battery storage looks like in the cabinet.

Storage Limits and Weights

Limits for the Storage of Energy Carriers

Group	Specification	Maximum threshold
1	Lithium-ion batteries — maximum 100 Wh	1,000 kg of energy carriers per fire compartment
1	Lithium-ion cells — maximum 20 Wh	1,000 kg of energy carriers per fire compartment
1	Lithium-metal batteries — maximum 2 g of metallic lithium	1,000 kg of energy carriers per fire compartment
1	Lithium-metal cells — maximum 1 g of metallic lithium per cell	1,000 kg of energy carriers per fire compartment
1	Hybrid batteries (lithium-ion and lithium-metal) — maximum 10 Wh and maximum 1.5 g of metallic lithium	1,000 kg of energy carriers per fire compartment
2	Energy carriers not classified under group 1	333 kg of energy carriers per fire compartment
3	Energy carriers not classified under group 1, integrated into vehicles, equipment, or machinery, and stored outdoors	33 kg of energy carriers per fire compartment with storage 2,500 m²
4	Damaged or defective energy carriers	30 kg of energy carriers per fire compartment
5	Energy carriers intended for product or material reuse (including deeply discharged energy carriers)	333 kg of energy carriers per fire compartment

Battery Weights

Battery type	Weight	Used for
Super Soco	19.4 kg	Scooter battery
Rad Runner	3.6 kg	Bike battery
Smartvelo	3.3 kg	Bike battery
