Then lay the sticker back down.

The dimensions are 3.78 x 7.24 x 8.86 inches, and the weight is approximately 12.35 lbs.

What is the expected battery life of the APC UPS Battery Replacement?

The expected battery life is between 3 to 5 years.

is this a new product or refurbished ? and will it fit the APC model bx 1550 G?

The product is genuine packed with APC box. It's brand new, not refurbished nor used. I don't know will it fit BX 1550 G? I can't find this model. Is it discontinue model? I suggest you to give a call to APC to find out the correct model# for replacement battery. In addition, APC has a recycle program for replacement battery called "Recycling Options" or you can trade-in your whole UPS. Good thing is APC will give you a free shipping label for you to ship your old battery back to APC. You don't need to worry about disposal. Hope it will help you. Good luck.
