Batteries in use for some time and then go in aging. Concrete expression of the resistance is greater, the charging time at both ends of voltage rise rapidly, so it will be easy to find for the circuit load control has been completed, the capacity is naturally “down”. The VGP-BPS2A VGP-BPS9A battery internal resistance due [...]
