Arlo system- using 230 volt inverter from leisure battery to power Netgear wireless router

[Swift]

I have one Arlo camera on my boat moored 70 miles away. I'm using the supplied Netgear router with a wireless router to enable remote activity to my iPad or iPhone. The power supply is provided by a 230 volt 600 watt pure sine inverter from a deep discharge leisure battery ,which in turn is charged by a 40 watt PV pack. My battery seems to discharge and cut out after about 5 days. ( obviously the recharge is not keeping pace with the A.C output)   Not being technically competent I am asking whether a larger capacity leisure battery would be the answer!? - the present battery is only 70ahr.. 

Can anyone help please?  I cannot afford a larger capacity PV system!!!!

A larger battery or multiple smaller ones would extend the life. However, that will only exacerbate the lack of PV charging.

Thanks for taking the trouble to reply- much appreciated. Sadly I cannot afford larger capacity PV system- might find an addition battery to link in
