Do we need to swab the batt charger as well? My Lobster premium charger is made by Soneil. I believe it has pulse mode charging to remove sulphation which the lithium iron batt is not compatible with.
I have also myself a lobster , I have the original 1amp fast charger , but I ended up buying the 3 amp premiun charger , because the 1 amp fast charger would take for ever . When the original 18 AH battery was fully discharged with the fast charger it would take 22hr 30' to recharge , so if I had to go back to back days to the park at the same time , I had to take it not completely recharged .

Premium charger solved this problem . Specially since I had already bought the Panasonic 22 AH and since it has more capacity it would take 30 hrs to be fully recharged . With the premium charger less than 4 hrs .

I live currently in Holland , and things here are more expensive than in the States . I can buy an 18 AH SLA for $60 , but the max time it can give me is around 4 hrs , and I do play 4 hrs , but that means full discharge , if with a SLA you go full discharge after full discharge , immediately your playing time dwindles a lot , then is buying time again .

I am not sure , but what I gather after reading some specifications is that Lithium batt with the same capacity than a lead acid , runs at least twice as long , so if for instance , a lead batt can give me 5 hrs playing time , from a lithium I can get 10 hrs .
I am not sure about this , that is why I would like to hear from someone who had had a Lithium batt .

Not that I am planning to play 10 hrs , but if they have the capacity to give you 10 hrs , and you play 4 , the depth of discharge is 40% and with such a low discharge , you can get 3,000 cycles .

You know what 3,000 cycles are ??? is playing everyday 4 hrs for the next 8 years . Then paying twice or thrice as much it would still be a bargain .
