If you connect two lead acid batteries together for loads only (somewhat difficult to achieve), the battery with the greater charge will try to charge the lower one. However, they will eventually stay equal but this will not last.
Check your battery chemistries – Sealed Lead Acid batteries for example have different charge points than flooded lead acid units. This means that if recharging the two together, some batteries will never fully charge. The result here would be sulfation of those that never reach a full state of charge, reducing their lifespan.
The combination of these two types of batteries into a hybrid storage leads to a significant reduction of phenomena unfavorable for lead–acid battery and lower the cost of the storage compared to lithium-ion batteries.
The basic concept is that when connecting in parallel, you add the amp hour ratings of the batteries together, but the voltage remains the same. For example: two 6 volt 4.5 Ah batteries wired in parallel are capable of providing 6 volt 9 amp hours (4.5 Ah + 4.5 Ah).
Despite being three years old, the 160AH lead acid battery in this setup is still functional. It is currently hooked up to a 1KW inverter and helps power my house partially during power outages.
Lead–acid batteries are popular mainly because of low cost and high reliability , what makes them attractive, especially in the developing countries. However, they feature short life-cycle and are not resistant to conditions that may appear in PV systems like undercharging, low state of charge (SoC), high charging current .

This can cause a voltage spike at the alternator that can kill the diode pack or regulator. That shouldn''t actually be an issue if a lead acid battery is in parallel as that will prevent the voltage spiking. The reason a VSR works ok for lead acid batteries is that their internal resistance is higher, and limits the current they draw.
Get Price >>With the aid of an external ammeter (1Ad.c. f.s.d.) the approximate charging period of battery (or battery pack) may be calculated. To calculate the time, first determine the total capacity of the battery i.e. two 6V 1.1Ah connected in parallel give a battery of 6V 2.2Ah, but when connected in series give a battery of 12V 1.1Ah.
