 Initial sales price - hence "to put in".

 Li-Ion has a much better long term cost because of the longer life,
OTOH I'm not sure it's worthwhile given the amount of battery technology
research going on. It seems like pretty much every week someone is
announcing something that outperforms Li-Ion in the lab, it may well be a
reasonable bet that by the time a new Lead/Acid install is worn out there
will be something much better than Li-Ion to replace it with.
