After 3 days of it on charging after receiving. It usually lights up green for a fully charged battery. Its still in red and not sure if it supposed to turn green on this type battery or I have a wrong charger for it because its lithium.

Seems like a great battery however why they would make it larger than 13 inches long beats me. Wont fit in the cradle where a group 31 deep cycle was. Not a big issue, but battery size standards are for a reason.

The 100 Amp 12V battery from Dyness is an outstanding product. The quality is excellent across the board — from the precise fit and clean finish to the reliable, high-performance function. It delivers dependable power, is well-built, and clearly engineered with care. We highly recommend it for anyone seeking a top-tier 12V battery solution.

Seems like a nice product, but don't judge it by appearance.Big question: why did the manufacturer/seller not ship a fully charged battery?That's what you get when you go to a battery store.The one I got was completely dead (voltage meter read zero upon arrival).Took two days to charge. NOT a good sign.
