Lead-Acid batteries ARE balance charged using a process known as "Equalization." The cells in the series string that have the highest charge are allow to be over-charged, and this in turn allows the lower cells in the string to fully charge as well.

We call this the balancing state, and it occurs during what would normally be the absorption (Constant Voltage) stage of lead-acid battery charging. Passive balancing is generally a slower process than active balancing and may take longer to achieve completely balanced cells.
Go from high charge to significant discharge without significant float time. This confirms what user 38367 mentions, that individual cell balancing would be beneficial for lead acid batteries in such remote area hybrid power systems using lead acid batteries.
Traditionally, lead acid batteries have been able to "self-balance" using a combination of appropriate absorption charge setpoints with periodic equalization maintenance charging. This characteristic of lead acid batteries is enabled by a secondary electrolysis (hydrogen producing) reaction within the electrolyte of the batteries.
Battery balancing works by redistributing charge among the cells in a battery pack to achieve a uniform state of charge. The process typically involves the following steps: Cell monitoring: The battery management system (BMS) continuously monitors the voltage and sometimes temperature of each cell in the pack.
The control circuitry is complex and a discrete implementation is large and costly. The LTC3305 lead acid battery balancer is currently the only active lead-acid balancer that enables individual batteries in a series-connected stack to be balanced to each other.

Get PriceWhen a lithium battery is full, trying to charge it more will cause damage. Conversely, in a car the "12 V" lead-acid battery is usually just charged with a fixed voltage of about 13.6 V. At that voltage it will take a small amount of charge current even when full, but unlike with a lithium battery, this does the lead-acid battery no harm.
