AI Customer ServiceCharging techniques in lead acid batteries take place using varying current magnitudes. Constant current charging techniques are tested to determine charge efficiency. The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries.
This suggests that the efficiency of charge can be ameliorated by using constant charging currents above 2A. So the best range of current magnitudes that can be used to charge this lead acid battery is between 2A and 5A.
The larger the electric charging currents, the greater the effective energy stored. Larger charging current rates provoke higher temperature increases in older than newer batteries. The charging and discharging of lead acid batteries using Traditional Charge Controllers (TCC) take place at constantly changing current rates.
In this paper, the impact of high constant charging current rates on the charge/discharge efficiency in lead acid batteries was investigated upon, extending the range of the current regimes tested from the range [0.5A, 5A] to the range [1A, 8A].
Thirdly, three constant charging current regimes (0.5A, 5A and 8A) were chosen within the tested current rates for which further electrolyte temperature monitoring tests were carried out, using two other lead acid battery samples of different health states.
Under the right temperature and with sufficient charge current, lead acid provides high charge efficiently. The exception is charging at 40°C (104°F) and low current, as Figure 4 demonstrates. In respect of high efficiency, lead acid shares this fine attribute with Li-ion that is closer to 99%.
