To charge more than five batteries simultaneously, connect one 12-volt battery charger across the series connection of the batteries as if each were being charged separately. It''s best to charge all the batteries at once. ... When batteries are unbalanced, some cells may be subject to overcharging or discharging, leading to accelerated ...
I connected them to my 24v charger to ensure they were charged to 100%, to synchronise my battery monitor. However, the voltages of the two batteries whilst on charge was markedly different: batt 1 15.1v, batt 2 13.8v. This immediately triggered an imbalance alarm from the battery monitor (mid-point voltage difference).
The two batteries are at a different SoC (State of Charge). Luckily, lead-acid batteries can be balanced through a prolonged charging cycle, which is exactly what you are doing. The battery that is the least charged continues to charge. The battery that is the most charged is converting that same current into heat and into generating hydrogen.
Another use for the "C" specification is when charging the battery. Some LiPo batteries can be quick-charged, and the maximum current you can give them is also defined with a "C" value. So a battery that is rated at 3000 mAh with a maximum charge rating of 3C can be quick-charged with a current of 9000 mA, or 9 amps. ... These are very ...

Yet by charging the battery in storage mode, the charger will charge your battery up between 3.7 and 3.8 volts. The second benefit to storage charging a battery every time is reducing the time it takes to charge that battery. But, again, this is because you''ve already charged the battery up to an optimal storage range.
