Of the smaller battery through the over discharging and over recharging described and shorten the life of the larger battery through under charging. How battery charging works with a parallel battery bank.

Charging 3 12v batteries in series. Next time you charge you should see the batteries are then closer in voltage at the end of the charge cycle. In theory a 6 volt 3 ah battery and a 6 volt 5 ah battery. Voltage if there is one. Plug in your charger to the electricity supply. The easiest way to fix a voltage difference is to charge the pack fully then bring up the lowest battery with a 12v charger placed on just the lowest battery. 6 volt agm battery has more life cycles.
To charge two 12 volt batteries in series youd need a 24 volt charger. All flooded lead acid or all agm. By charging 6 volt batteries in series with a 12 volt charger you allow your off grid electrical the true capacity it needs. Connecting batteries of different amp hour ratings in series. This makes charging the battery difficult because the increases in voltage will provide different charges to each battery. Others have a meter that shows the charge rate and once its near zero your batteries are charged.
Lets suppose you have 3 different 12v batteries wired in parallel to supply 12v power to your rv. They can have different capacities on account of size or age but the same chemistry eg. You do not need to disconnect the series connections to do this as long as you can access just the lowest battery. Two 6 volt batteries in series vs one 12 volt life cycles. Charge all the batteries at the same time. Turn on your charger ensuring it is set to charge at 12 volts.
For a plethora of information. Some chargers have a light that illuminates once charged. Use another set of cables to connect the open positive and negative terminals to your application. Discharging down do 80 depth of discharge 600 700 on average. Thats the pat answer. You need to overcome the total voltage of the series batteries 12 v 12 v 24 v to drive.
Charge more than five batteries by connecting one 12 volt battery charger across each battery in the series as if each battery were the only one being charged. Let your batteries charge until the charger indicates they are fully charged. When charging 3 12v batteries in series with one another each voltage of each battery would increase in an amount dictated by ohms law v ir for voltage v in volts current i in amperes and resistance r in ohms. To connect batteries in a series use jumper wire to connect the negative terminal of the first battery to the positive terminal of the second battery. In theory a 6 volt 5 ah battery and a 12 volt 5 ah battery. A 12v agm battery on average has only 150.
