I have one one these in the 150mah size for my camper. I bought the charger separately.

Charger works great. Haven't had the battery long enough to judge.

I have it hooked up in parallel to a different battery with BT for charge management.

How long to charge to full from empty?

edit: never mind, read too quickly and missed you have different one.

Charging @ 20A rate is 20AH per hour so it would charge 100 AH battery in 5 hours.

I've bought 2 pairs of the 150AH battery when price drops to about $170 each. I'm running them in series pairs (~25V). It looks like the 100 amp hour battery does NOT have Bluetooth monitoring, so I think I would hold out for that. My batteries came in at about $0.09/AH. I also have the charger and it works fine, but I mostly charge with solar.

It is probably more like 6-7 hours. The 20A is for an empty battery as they get full, think of it as a balloon getting filled to its max. The charger automatically slows down and by the end is a trickle charger. That is why a Tesla can go from 20-80% in 40-45 minutes but 80-100% can take another 40 minutes to an hour. Its best if you charge to less than 100% if possible, and then store it at less than 70% if you want it to last considerably longer.

Do you mean the charger or the battery? It looks like you should be able to use the charger as it is compatible for lead acid or AGM batteries. I wouldn't use the battery in your car. Although I'm sure it would work, car batteries are made to endure high temperature, vibration, etc. also, car batteries are constantly charged by the alternator, and although lipo4 batteries can remain at 100% soc for longer than other lithium chemistries, it's not made for it like lead acid, and isn't supposed to be constantly fed a charge.
