anyone know if the factory fitted battery on a 12 plate gtr1400 is LEAD/ACID type.
I don't my friend but a quick phone call to Alfs will answer your query. :wink:
The OEM battery is an AGM (Absorbtion Glass Mat) as are most batteries these days.
They still have lead plates and sulphuric acid but have fibreglass matting between the plates so they use less acid and are mostly spill resistant.
So the answer is yes,... sort of.
I believe that a couple of the US forum guys have replaced theirs with the new (very expensive) LFP (Lithium-Iron-Phosphate) batteries and like them but at those prices is it worth the difference?
