Same-day delivery from Amazon. Amazon prime is awesome!

Can’t beat the price and next day delivery off Amazon verses buying one in the store for 2 to 3 times the price just for a basic lead acid. Made in Taiwan like some of the other known brands.

Just received this today, and it was already fully chores, ready to go! I purchased this because the price was amazing and the warranty beat anything else that I found.

Very reasonable prices and delivery considering the holiday schedule. Will be my future supplier.

Appears to be a good, new battery for garage door opener. Arrived w/I 2 days. Easy install, appears to work as expected.
