Hi TI Expert,
I'm using BQ24450 for charging the Lead Acid.
Vin: 15.57V
VTH : 10.5V
VFLOAT: 13.8V
VBOOST: 14.7V
Vbat min: 10.7V
Ipre: 10mA
trickle charge rate: 10mA
charge rate set: 400mA
At the first few days of testing, it charged up to around 13.7V and it maintain at the voltage of 14.8V (Vboost) for 5 days and it seems like it is not dropping down to Vfloat of 13.8V that I set.
I worry that if the lifetime of the battery will be shorten if it is charged with this high voltage continuously.
I also tried to lower down the max-charge current, still the Vout maintain at 14.7 V.
Please advice what i should do.
Thanks,
Br,
Jason
