It's all in the riders manual.
Remove the riders seat, using the ign, key. Under there you will find a hex key. Move down to the right side panel, the black plastic affair. At each corner is a fastening (4 in all) - using the hex key give each a half turn anti-clockwise & wriggle them free. The front lower can be awkward if you have OE crash bars installed. The panel is then held on a press stud mid way along it's top edge - just pull outwards gently & the panel will come away to reveal the battery. This is sealed for life, maintenance free. Make sure the terminals have been tightened down fully - some of us have found them slightly loose. Fit a Pigtail if you want to use a trickle charger
Whilst you are in there, ahead of the battery is a pack containing the usual crap toolkit - you may wish to customise it's contents. Also up behind the toolkit area are, carefully hidden, two plugs for accessories - 3 wire for aux. lights & a 4 wire plug which was intended for heated grips on the standard model, but seems redundant on the ES.
Enjoy your new ride - there is lots of good advice here, many now with the Gen 2 ES model.
