Is this aftermarket battery OK? 2014 R1200RT

[Kunkies]

My second battery is beginning to show signs of losing its charge.  Purchased a XTreme 12V AGM XTAX20CH-BS 12V 18Ah replacement battery which is 18Ah versus the OEM 16Ah yet exact same physical size.  Is that OK??

Bike:  2014 R1200RT
Accessories added that draw power:  Denali CANSmart CANBus Controller, Denali DR1's driving lights x2, Denali DRL Accessory lights amber x2, Denali B6 dual rear brake lights, I ride year round; so using the CanBus 12V DIN maximum draw with heated gear is 9.2amps.


Thanks in advance for your input, feedback.

My VIN shows I have a second battery on my 2017 R1200RT. The bike is new to me... I don't see a second battery or signs where it would be anywhere, where do they keep it?

is it an ex police bike ?

Sounds like it to me. Some forces have the second battery in the tail box others in the fairing cubbyhole
