Safe Battery Charging for MEWPs: A Practical Guide for Site Teams in the Gulf
Battery-powered Mobile Elevating Work Platforms (MEWPs) are increasingly used across construction sites, warehouses, commercial buildings, industrial facilities and maintenance projects throughout the Gulf region.
In locations such as Dubai, Abu Dhabi, Riyadh, Jeddah, Dammam, Doha and Manama, electric scissor lifts and other battery-powered access platforms can provide a quieter and cleaner alternative to diesel-powered equipment, particularly for indoor work and projects where emissions and noise need to be controlled.
However, safe battery charging is an important part of operating electric MEWPs. Incorrect charging practices can damage batteries and charging equipment and may increase the risk of electrical incidents, overheating or fire.
This practical guide explains the key considerations for safely charging MEWP batteries on sites across the UAE, Saudi Arabia, Qatar and Bahrain.
Important: Always follow the MEWP manufacturer's operator and maintenance instructions, together with the requirements of your site risk assessment and applicable local health, safety and electrical regulations.
Quick Summary
MEWP batteries should be charged using the correct, manufacturer-approved charging equipment in a suitable designated area. Before connecting the charger, site personnel should check the battery and charging equipment for any issues, protect cables from moisture and physical damage, and confirm that the charging location is suitable for the specific battery system.
Lead-acid and lithium-ion batteries have different charging and safety requirements, so operators should never assume that the same procedure applies to every MEWP.

Why Is Safe MEWP Battery Charging Important?
Electric scissor lifts, boom lifts and other battery-powered MEWPs rely on correctly maintained battery systems for safe and reliable operation.
Poor charging practices can contribute to:
- Battery overheating
- Electrical faults
- Charging equipment damage
- Fire or explosion risks
- Reduced battery performance
- Shortened battery service life
- Unexpected machine downtime
- Damage to the MEWP
For rental equipment, correct charging is particularly important because it helps keep machines available for the duration of a project and reduces avoidable damage caused by incorrect charging or handling.
IPAF's current battery guidance covers the safe use, charging, storage, inspection, maintenance and disposal of batteries fitted to MEWPs, including flooded lead-acid, AGM, gel and lithium-ion batteries.
Where Should Electric MEWPs Be Charged?
MEWP batteries should be charged in a designated and suitable charging area that follows the manufacturer's requirements and the site's safety procedures.
The charging area should:
- Be clean and organised
- Provide sufficient space around the machine
- Minimise trip hazards
- Protect charging leads from damage
- Be away from ignition sources
- Provide appropriate ventilation where required
- Protect electrical connections from water and other environmental hazards
- Be accessible for emergency response
Charging in Gulf Conditions
The Gulf's hot climate makes the selection of a suitable charging location particularly important.
Where possible, charging should take place in a controlled environment that meets the battery and charger manufacturer's specified operating conditions. Batteries and charging equipment should not be exposed unnecessarily to extreme temperatures, direct sunlight, water ingress or other conditions outside their permitted operating range.
Site teams should check the manufacturer's instructions for the permitted charging temperature and environmental conditions for the specific machine and battery system.
Managing Gulf Heat During Battery Charging
High temperatures, direct sunlight and dust can affect battery charging conditions on Gulf worksites. Charging areas should therefore be selected carefully and kept away from prolonged direct sunlight and unnecessary exposure to dust.
Site teams should check the battery and charger manufacturer's specified temperature limits before charging. If conditions are outside the permitted range, charging should be delayed or moved to a suitable location in accordance with the manufacturer's instructions.
Keeping the charging area clean and maintaining suitable environmental conditions can also help protect charging equipment and reduce avoidable battery-related issues.
Lead-Acid Battery Charging
Lead-acid batteries require particular attention to ventilation because hydrogen gas can be released during charging.
They should be charged in a well-ventilated area away from ignition sources, such as smoking, welding, flames or other sources of sparks. IPAF's 2026 guidance specifically recommends well-ventilated, designated charging areas for flooded lead-acid batteries.
What Should Operators Check Before Charging a MEWP?
A short inspection before charging can identify damaged equipment before it becomes a safety problem.
Check the Charging Lead and Plug
Before connecting a MEWP to a charger, inspect:
- Charger cables
- Plugs
- Connectors
- Extension leads, where permitted
- Cable insulation
- Visible signs of cuts, crushing, overheating or other damage
Do not use damaged charging equipment. Report defects and have them assessed by a suitably competent person in accordance with the manufacturer's instructions and site procedures.
IPAF highlights damaged charging leads and plugs as a potential electrical safety hazard.
Check the Battery
Operators should also look for obvious signs of damage, leakage, unusual swelling, corrosion or other abnormalities.
If a battery appears damaged or behaves unexpectedly, stop and follow the manufacturer's instructions and your company's reporting procedure. Do not attempt unauthorised repairs.
What to Do If a Battery Becomes Damaged or Overheats
If a MEWP battery becomes damaged, unusually hot, starts smoking or shows other abnormal signs, stop using the equipment and follow the manufacturer's emergency procedures. Do not attempt to inspect, repair or handle a damaged battery unless you are authorised and suitably trained to do so.
Keep people away from the affected area and report the situation immediately through the site's safety and emergency procedures. If there is smoke or a fire, follow the site's emergency plan and contact the appropriate emergency services.
Is the Correct Charger Being Used?
Using the correct charger is essential.
The charger must be compatible with the specific battery system and MEWP. Lithium-ion batteries should only be charged using a charger designed and approved for that battery system.
Using incompatible charging equipment can increase the risk of battery damage, overheating, fire or explosion.
A charger should only be used when it has been confirmed as compatible with the specific MEWP and battery system; a matching connector alone does not confirm suitability.
Always check:
- 1. The MEWP manufacturer's instructions
- 2. The battery specifications
- 3. The charger's specifications
- 4. The required supply voltage
- 5. Any transformer requirements
- 6. The site's electrical safety procedures
IPAF notes that MEWPs may use different supply arrangements depending on the region and machine, so the correct voltage and transformer requirements must be confirmed from the machine documentation.
Are Extension Leads Safe to Use?
If an extension lead is permitted by the MEWP and charger manufacturer, it must be suitable for the electrical load and used correctly.
Operators should:
- Fully uncoil the extension lead before use
- Keep the lead as short as practical
- Protect it from vehicles and pedestrian traffic
- Keep connections away from water
- Prevent cables from becoming trip hazards
- Inspect the lead before use
- Avoid connecting multiple extension leads together
Long or unsuitable extension leads can contribute to voltage drop and overheating. IPAF specifically advises keeping extension leads as short as possible and fully uncoiling them during use.
Where possible, use the charging arrangement specified by the MEWP manufacturer rather than relying on additional extension equipment.
How Are Lithium-Ion MEWP Batteries Different?
Lithium-ion batteries are increasingly being used in modern powered access equipment.
| Feature | Lead-Acid Batteries | Lithium-Ion Batteries |
| Charging | Typically require a designated, well-ventilated charging area. | Charging requirements depend on the battery and manufacturer specifications. |
| Ventilation | Important because hydrogen gas can be released during charging. | Normal charging does not produce hydrogen gas like flooded lead-acid batteries. |
| Maintenance | Generally require more routine maintenance than lithium-ion systems. | Usually requires less routine maintenance. |
| Charging flexibility | Charging should follow the battery manufacturer's recommended procedure. | Some systems may support opportunity charging when permitted by the manufacturer. |
| Safety considerations | Avoid ignition sources and ensure suitable ventilation during charging | The battery and its Battery Management System (BMS) must be protected and operated according to manufacturer requirements. |
| Typical applications | Commonly used across a range of electric access equipment. | Increasingly used in modern electric MEWPs and applications requiring flexible electric power. |
| Key consideration | Correct charging conditions, ventilation and battery maintenance are important. | Use the approved charger and follow the manufacturer's charging and BMS requirements. |
However, lithium-ion batteries have their own safety considerations.
The main safety concern associated with lithium-ion batteries is the potential for fire or thermal runaway if a battery is damaged, incorrectly charged or otherwise subjected to unsafe conditions. IPAF identifies fire or explosion leading to thermal runaway as a key risk for lithium-ion MEWP batteries.
What Is a Battery Management System (BMS)?
Many lithium-ion battery systems use a Battery Management System (BMS) to monitor and control important battery parameters.
Depending on the system, the BMS can help manage:
- Battery temperature
- Charging
- Voltage
- Battery condition
- Protection functions
- The BMS is a safety-critical part of the battery system.
Operators must never bypass, disable, modify or replace the BMS with non-approved components. IPAF specifically identifies the BMS as a safety-critical component of lithium-ion MEWP battery systems.
Can MEWPs Be Operated While Charging?
Generally, a MEWP should not be operated while it is connected to a charger unless the manufacturer specifically permits this operation.
Moving or operating a machine while connected to charging equipment can create risks involving cables, connectors, electrical equipment and the surrounding work area.
Before attempting to operate or move a MEWP during charging, check:
- The manufacturer's operator manual
- The machine-specific charging instructions
- Site procedures
- The risk assessment
If the manufacturer does not specifically permit operation while charging, disconnect the charging equipment before moving or operating the machine.
What Is Opportunity Charging?
Opportunity charging means charging a battery during suitable periods of downtime rather than waiting for the battery to become heavily discharged.
This may be suitable for some lithium-ion MEWPs and certain applications, but it should not be treated as a universal charging method.
The appropriate charging strategy depends on:
- Battery chemistry
- MEWP model
- Charger specification
- Battery Management System
- Manufacturer instructions
- Project requirements
Operators should follow the charging procedure specified for the particular machine rather than assuming that frequent short charging sessions are suitable for every battery.
