PRODUCT DETAILS
The Yuasa Yucel NP4-12 is a maintenance-free, 12V 4Ah sealed lead acid battery that is commonly used in alarm systems, emergency lighting and other stand-by power applications requiring a high-rate discharge. Each battery is individually tested and features a longer life span than conventional lead acid batteries, making them ideal for critical applications where reliability is paramount.
Featuring AGM (Absorbed Glass Matt) technology, the NP4-12 retains the maximum number of electrolytes in its cells and the valve regulating design ensures safe, low pressure venting of excess gas.
Features:
- EUROBAT Classification: 3 to 5 years 'Standard Commercial'
- General purpose VRLA battery
- Lead Calcium Grids for superior life
- Absorbed Glass Mat construction with no free acid
- Gas recombination
- Manufactured world wide
- Good recovery from deep discharge
- Operation in any orientation (excluding continuous inverted use)

| Handles |
Batteries must not be suspended by
their handles (where fitted) |
| Vent valves |
Each cell is fitted with a low pressure
release valve to allow gasses to escape and then reseal. |
| Gas Release |
VRLA Batteries release hydrogen gas
which can form explosive mixtures in air. Do not place inside a
sealed container |
| Recycling |
YUASA's VRLA batteries must be recycled
at the end of life in accordance with local and national laws and
