Lead-Acid battery charging time?
Hi, If I have 12V 2Ah Lead-acid battery how long should it take for it to charge if it's connected to a mini wind turbine outputting approximately 7 watts continuously. Controller output voltage: 12V (not sure if this is relevant)
Thanks
A 12V battery charges at 13.8V. So:-
Charging current = 7/13.8 = 0.51 amps
Charge time = 2/0.51 = 3.9 hours
This needs a good charge controller to avoid damage to the battery. Lead acid batteries are easily damaged if overcharged, and the wind is fickle.
