I have one of the Firehouse Arc2 strobe lights and it failed after very limited use. The little battery is puffed and shows signs of leakage. It is out of warranty of course and FHT says too bad for me since it is over 90 days since purchase. FH says I either overheated the battery or charged it when hot. I don't believe either of those to be my case. They don't even offer a replacement battery! They charge a lot for their lights and then won't even sell me a new battery which they buy in bulk for about $1 max. cheap I won't be buying anymore of their products after this experience. Anybody know of a good source for a LDR 602025 3.7V 240mAh battery?
