In short, a LiPoFe battery can take more charge faster than a lead acid battery can, so any charging system that will charge lead acid, will be like a trickle charger for the LiPoFe battery and will not harm the LiPoFe battery at all. As long as the lithium battery and lead acid charger are both rated for 12V.
The chemical reactions are again involved during the discharge of a lead–acid battery. When the loads are bound across the electrodes, the sulfuric acid splits again into two parts, such as positive 2H + ions and negative SO 4 ions. With the PbO 2 anode, the hydrogen ions react and form PbO and H 2 O water. The PbO begins to react …

The first step of removing single cells from a battery was to drill holes into the lid above Cells 2, 4, and 6. The acid density of Cells 2, 4, and 6 was measured, each at top, middle, and low levels and acid samples were then taken for future analysis, shown in Table 2.The acid from Cells 2, 4, and 6 was carefully and stepwise drained.
It is important that the battery charging device has a battery-temperature sensing ability, and applies a temperature-compensation to its charge voltage. For example a battery whose temperature is 30°C at the start of a charging cycle may well rise by a further 10°C during charging.
Lead acid batteries are strings of 2 volt cells connected in series, commonly 2, 3, 4 or 6 cells per battery. Strings of lead acid batteries, up to 48 volts and higher, may be charged in series safely and efficiently. However, as the number of batteries in series increases, so does the possibility of slight differences in capacity.
