Tiger Battery

What battery is fitted on the Tiger 900 (2021) GT Pro, the manual states its a
YTZ–14S but I am unsure whether this is a Lithium or sealed lead acid / gel /AGM. I wish to buy an optimate charger / optimiser. Thanks for any info.

 

Thanks for the reply Andy

 

I have the optimate plug being fitted as a Triumph accessory which presumably accepts the chargers lead

 

The wife won’t be happy, she’s bought the optimate lithium charger for my birthday which will need to go back for an optimate 6
