PRODUCT DETAILS
The Yuasa Yucel NP2.8-12 is a maintenance-free, rechargeable 12V 2.8Ah 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 NP2.8-12 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)
