Lead acid batteries will usually recover if recharged from 5 volts and not left that way for too long a period. If you do that more than once or for more than a day or two, you will seriously shorten it's life, as the life of a lead acid battery is mostly determined by the sulfur that builds up on the plates, and most of the sulfur is deposited when the voltage is down.

It has no charge at 11.9-12 volts... charge it.
Did you put the new battery on slow charge overnight before you installed it? Running down to 5V is unusual, maybe you have an accessory that is on and don't know it? Recharge the battery unhooked, let it rest for an hour and check the voltage... let us know.

Stores are awful about their new battery "quick charges" they do as they send them out the door. I have gotten better life by then taking them home and leaving them on a Battery Tender overnight.
Polar and passx like this.

Ridden wet. Put up hard.

Agree, a brand new battery is best slow charged..... I think the OP will be OK with a do-over unless there are other factors.

Yuasa used to spell out the need for a slow 6 hour charge as “break-in” before slamming the new battery with the vehicle’s charging system. Today they simply say the battery needs to soak after electrolyte is added, followed by a slow charge.

I ready like the Yuasa method - buy it dry, let it sit (dry) till you need it, add the electrolyte, put it on a charger for a bit, install. When i think the time is coming for a new battery, buy one from Amazon and just store it. If I get rid of the bike before the battery goes, it becomes a present (or selling feature) for the new owner.

I slow charged it after putting the acid in it, it is agm, I had to bump it to 12 volts before the yuasa 1 amp charger would charge it, it fully charged the bike started right up,big hesitation on hard acceleration, does the ecm have to learn after each time the battery is unhooked, thanks for your responses

I could be wrong but I don't think the ECU is that advanced. The fuel mixture runs off a predefined map mostly (open loop) and adjusts to O2 sensor input when cruising (closed loop). I don't think it has a learn mode like most autos.
