The media could not be loaded. It seems there are a few reviews stating a short lifespan of these Casil batteries.From my experience, the life is fine, 4 years so far.It has been used for various lighter use tasks, as solar storage, to run 12V devices and the like. But the main thing is that it remains as good as it was on day one. In the video, the battery voltage is measured and its overall age is shown by the scruff wear on it.Now, it's use is as an emergency spare for our car battery, should that one fail.Nothing wrong with it, works great and is still going 4 years later :)

Old Batteries no longer held a charge. These were the correct replacement batteries

Nice battery with good amp hours. I use this for my Astro-photography rig, it runs my telescope, camera with cooler, and I use it to charge my laptop when it needs it. So far I’ve gotten between 4-5 hours of run time, and if I use it without the laptop I’m well over 6 hours. If you know how many amps your equipment takes, then you can get the most out of it.

Casil claims to have a 12 month warranty. After 4 months mine will no longer hold a full charge. Amazon will not help because I’ve had it for more then 90 days. Amazon gave me contact information for Casil. I emailed Casil and got no response. I called and talked to a friendly enough rep who said the individual in charge of the Amazon account would get back to me in a few days. Over a week later I’ve heard nothing.

We’ll l see how long it’s lasts. Considering most batteries only last a year. One will tell

I think I got a good deal on the batteries and work great

Held its charge but didn’t release its charge to use it always said 100% battery life but never worked after 2-3 months save your money don’t buy this product if your gonna need a battery that works after 2-3months

Works great for the job I’m using it for. Using it to run LED lights every night for about 5-6 hours, works well, and charges up good
