Got a new 12A battery and it is still on yellow after 6 hours of charging. How long does it take to charge this battery?

Because it charges at 2A, it takes 5-6 hours (12/2 = 6; makes sense) but you could get a 4A charger and cut it by half.

Thank you. It''s been on the charger about 6 hours and its still yellow. I will wait a little longer. Battery charger makes a lot of noise when the fan is going.

Light just went off (which means disconnect). Took about 6 hours for the initial charge.
And yes, I can verify that there is a Neo Carbon 12a battery.

Nice. Neo's charger works at 42V and 2A. 6 hours sounds reasonable if it was drained fully.
I never drain the battery to its last bar and therefore I only need ~3 hours.
Many people seem to want fast charging. It could be done but there is a reason behind why 2A charger is more popular.
If you charge at 4A - 6A, the battery assembly could heat up slightly. One needs to arrange the configuration (series or parallel) very carefully to minimize heating and maximize charging efficiency.
Extra info: Tesla's supercharger charges at ~380V-400V and at ~250A and the USP of Tesla is their battery pack and how it is configured/ cooled to maximize range. They suggest not to use supercharger too frequently. 220V is the preferred method. This is to avoid build up of heat inside the packs.

charger is a non-serviceable item and any attempt to open the case will typically voice warranty. The fan seemed to quiet down after a few minutes.
