It is normal to charge lead-acid batteries in series. As they are used, the cell voltages will change, which is why they are not charged in parallel. If they were charged in parallel, the one with the high voltage wouldn't get much current, and the one with the low voltage would get too much current.
Typically Lead acid batteries have a DOD of 50% (Please refer to battery manufacturer's specifications for your specific battery) but in real world terms this means a 100AH lead acid battery has around 50AH of useable power before the battery is considered “flat” and is showing a voltage of below 11.9V DC. A typical Lead Acid battery
It would also be a good idea to use a charger that adjusts voltage to maintain a constant current. Typical lead acid batteries can be charged at 0.1C (a 1Ah cell can be charged at 0.1A). A 'smart' charger will also make balancing the cells much easier.
The goal of the series / parallel configuration is to increase BOTH the voltage and capacity. Batteries that are ONLY in parallel keep the same voltage and increase their capacity. Batteries that are ONLY in series keep the same capacity and increase their voltage.
When connected in series the battery capacity will remain the noted capacity of one battery, only the voltage will increase. For example, two 12V 100AH batteries will give a total battery capacity 100Ahr at 24V. Four 12V 100AH batteries, give a total battery capacity of 100AH at 48V please see Fig. 1.
As covered in the section Connecting batteries of different voltages in series above, the greater the differences in either voltage or amp hour rating, the more the discharging and recharging is unbalanced and the more damage you do to the batteries through over-discharging and over-charging the weaker ones and under-charging the stronger ones.
