No it doesn't, because it is not sealed and has the traditional caps on top that you can remove to add water. Buying that would be a last case scenario for me because I'm pretty sure I can jump start my Tesla and keep it running with a weak battery.
The cheapest non-OEM battery I've seen available is at AutoZone for $70 (

Long term, I would want to use a battery that has a port for the vent hose so that any gases that might get released during charging don't cause corrosion around the battery area.
