Dear Hynee Customers,

The battery is the core power source of Hynee aerial work platforms, including self-propelled aerial work platforms,vertical mast lifts ,vertical boom lifts and scissor lifts. To extend battery life and ensure safe operation of your electric mobile elevating work platform (MEWP) , please pay close attention to the following key points – especially under different working conditions such as outdoor construction, warehouse logistics, and industrial maintenance.

1. Four Things That WILL Damage Your Battery

❌ Don’t do this	✅ Correct practice
Charge >24 hours	Stop after 5–8 hours
Charge below 0°C	Warm up battery first
Charge in enclosed space (chassis,box)	Charge in well-ventilated area
Use wrong / old charger	Use Hynee original charger

2. Regular Checks

Inspect at least once a month:

Voltage – Measure total voltage and each battery’s opencircuit voltage. Deviation should not exceed ±0.1V

Appearance & cleanliness – Keep casing clean and dry; ensure vent is unobstructed

Terminals & connections – No looseness, corrosion, or leakage. Apply anti-oxidant paste if needed

Casing condition – No cracks, deformation, bulging, or leakage

3. Typical Faults & On ＆Site Actions

Symptom	Common Scenario	Action
Bulging / deformed battery	Long-term overcharge or high- temp charging	Stop use immediately. Check charger. Improve ventilation. Replace battery.
Abnormal heat during charging	Wrong charger or internal short circuit	Stop charging. Contact a professional.
Rapid voltage drop when idle	Dirty casing ( leakage) or high self- discharge	Clean casing. Try a top-up charge; if no improvement, replace.
Low capacity	Insufficient charging or high connection resistance	Run one full charge-discharge cycle. Clean all connection points.
