6-GFM(G)-100 12 Volt 100 AH battery employs Absorbed Glass Mats (AGM) technology which contains the acid, or the electrolytes are absorbed in glass mats surrounding the lead plates. 

They will not spill when broken, there is no liquid that will freeze, and heat generation is reduced during the charge and discharge cycle. 

Moreover, AGM batteries have very low self-discharge rates, ideally suited for all off-grid, back-up power, and power supply applications.

This is a 12V 100AH SLA Battery with an NB terminal. 

The high impact resistant battery case is made up of a non-conductive ABS plastic, this material has a strong resistance to shock, vibration, chemicals and heat. 

It is valve regulated which makes it impossible to spill, and with its tightly sealed construction, it can be operated from any angle! It even has a low pressure safety release valve.

Excellent Deep Discharge Recovery Performance, wide Operation Temperature Range. Maintenance-Free Design with Spill Proof Construction, Long Shelf Life.

12V 100AH solar battery meet certifications:
