How do you charge a battery in parallel?

It should be as simple as charging your batteries individually. Ideally the cells should remain at the same voltage after discharging in parallel, but this really depends on the quality/technology/relative-age of the batteries. The further apart the voltages, the more you have to 'over-charge' one cell to get the other up to voltage.

If you put the batteries in parallel, the total voltage remains the same. This is the same as connecting 3 identical reservoirs to a pipe: you are not increasing the pressure.

Can two battery cells be connected in parallel?

First, the observations relate to the connection of two battery cells in parallel (2p). The effects shown by Brand et al. [ 3] occur when a linear OCV and no SoC dependencies of the impedance parameters are assumed. In this study, the time-dependent impedance is also analysed at different frequencies of the total current.

Does a parallel circuit have a higher current than a drained battery?

The current won't be larger, since the voltage is the same. What will triple is the total charge released before the battery is drained. Intuitively, a parallel circuit requires the current to split in as many flows as branches, because the current must pass through all branches at almost the same time.

What is a parallel connection in a battery?

Definition and Explanation of Parallel Connections In a parallel connection, batteries are connected side by side, with their positive terminals connected together and their negative terminals connected together. This results in an increase in the total current, while the voltage across the batteries remains the same.
