Delivery was fast...first time out the ultrex was on high all day...and they were just as strong at 3 as they were at blast off....thanks for the battery advice ..Matt and BTL....oh and they were priced great and I didn't have to worry about delivering old ones to the store

So far so good I have four of them in my boat 3 for trolling and the newest one to help run my electronics went out this weekend and had no problems

I would give 5 stars, but I think there is always room for improvement so I give 4.5. Overall great battery and so far works flawlessly.

Order Saturday receive on Wednesday to eagle mountain lake Texas thank you for the great service….

I have had the 31 AGM in my boat for over a year now, and used it in both extreme hot, and below freezing conditions. The 31 AGM in my opinion is the very best cranking battery on the market today. Best Battery Period!
