I don't like to be the bearer of bad news, but it looks like there are no longer replacement batteries available for that lantern. Please see
this link for repair parts from coleman. (
also possibly here.) There is a customer service number listed at the bottom of that first page that will put you in touch with a Coleman representative, who may be able to suggest an alternative choice for your lantern. Failing that, the only solution I can recommend would be to take the lantern to one of the aftermarket battery suppliers (such as Batterys Plus, etc.) and see if they can provide you with a non OEM version of the battery you need for your lantern to take a charge.
Good luck. I hope you're able to find something.]
