The Cigar Oasis Excel Battery pack comes with a short cartridge and a rechargeable Li-ion battery attachment. PLEASE NOTE: This unit is ONLY compatible with Cigar Oasis Next Generation Excel models. Dimensions: 6(L) 2(W) 2(H). Avoid frustration by checking your model BEFORE you order.
Bottom line: If you have the Oasis Excel and you re happy with it, leave it plugged in and forget the battery pack. It doesn t buy you a lot of time unplugged and the battery life declines quickly. I have had the company exchange me battery packs a few times and the most recent doesn t work at all.
