Great battery.  This puts an end to any leaky battery fluid in my jets ski.  I plan to replace all of the conventional wet, open cell batteries in my jet skis with these.  It also turned the starter at near full speed when the charge was down to 10%.  I hadn't used the ski for a couple of months and allowed the battery to slowly discharge.  It started right up.  I then checked the battery condition with the battery charger and determined the low charge status.  I was very impressed.  Good purchase.
