    I purchased this battery to be an auxiliary battery for a VW Vanagon. Based on the dimensions listed, it should have fit under the front driver seat. Unfortunately, those dimensions and the images didn’t see to indicate that the terminals are taller than the case of the battery. Since they stuck out above the case, they would not fit in the compartment where I intended to install it without some sort of modification. I am happy with the speed of delivery and it didn’t seem to have any issues other that the size wasn’t exactly correct.

    The two 40amp batteries on my scooter wouldn’t charge any longer. These two 50amp replacements are the bomb!

    The battery was a replacement battery for a scooter and works better than the original battery. The order was painless and it arrived before the estimated date of arrival.

Arrived fast
Using it in a large surge protector to protect electronics in a CNC milling machine. In a power outage, the battery maintains current for machine memory.
Purchased at Home Depot. USPS left battery the MAILBOX , not taking it inside, telling ORDER DELIVERY! SO BATTERY WAS IN THE MAILBOX FOR 2 DAYS..TILL I started to ask QUESTIONS!
Worked great. Perfect fit on my cub cadet
Fast … Easy … Works !
Fast shipping and excellent value !
Great price for a great battery.
Put it in my generator and worked perfectly. No issues other than the box arrived very much covered in dust from the delivery vehicle I assume.
Put it on and it fired right up the first time in months. No jump needed.
Ordered the ML5-12 from Amazon.ca to replace my garage door-opener battery and arrived within 2 days. Well packaged, already had over 12V charge. Exactly the same size as the Chamberlain Original battery I was replacing (Model #4228). Fit perfectly in the opener battery compartment and worked right away. For around a third of the cost I’ll definitely be ordering the Sam again in a few years when it’s time to renew.
