It hooked up easily to my Wayne back up sump pump as advertised that it would do. It came fully charged and when we tested out the backup pump everything worked as it should and the battery kicked in with no problem. I can't say any more than this at this time, and honestly hope that I never have to say anything more! It is difficult to write a review about a product that you purchase in hopes that you never ever had to use it! However, I feel secure now that my basement is protected by the whole system and by this battery that was less expensive than the others I looked at and works very well with the system I purchased. Review: Excellent battery - I bought this battery for my backup Wayne's sump pump. The battery held its charge for only about 4 1/2 months. Not very satisfied that is all the longer it lasted. I contacted Mighty Max and they told me to give it a good charge. It has held a good charge. I would definitely buy again and recommend this battery. ## Features - ML75-12 SLA is a 12V 75AH group 24 Sealed Lead Acid (SLA) rechargeable maintenance free battery - UL Certified - Dimensions: 10.24 inches x 6.61 inches x 9.06 inches.
