My mate and I each have a R1200GSA 2017. The batteries now need to be on battery tenders all the time. Each time we’ve forgotten and left the bikes off.the tender for a few days, the bike won’t start.
I bought 2 Lithium batteries from
Motorworks. What fantastic service! They rang to check I actually wanted 2 and dispatched overnight.

When the boxes arrived, I thought they were empty. Instead of 4.9Kg, they were 830gms! All the time I was fitting them, I thought they couldn’t possibly work. They do! I’ve put the Ctek pigtail with the charge indicator and they are consistently at the high point. I’ve checked the voltage when starting, running and from time to time in the garage, all seems well.
I ordered an ELA05655 battery. It was a JMT lithium HJTX14H-FP-SI. JMT is a German company so the battery meets the German safety specifications. LiFePO4 (Lithium Phosphate), is described as “less cell density than Lithium Ion which makes them less volatile, safer to use and almost a direct replacement for AGM packs”.
The battery is so small, there are some spaces supplied to raise the battery to the correct height. It is a direct replacement for the standard battery. I would have NO hesitation in recommending both this specific battery AND
Motorworks.
