At least for me and all the batteries i''ve charged so far.Never measured the voltage right after the fill up. Do charge your battery after it has cool down (reaction is over) and you have recheck the acid level.

1 Introduction. With the rapid development of the automobile industry, the production of lead–acid batteries (LABs) as the automotive ignition power source and energy storage devices has experienced enormous growth during the past few decades.

A one-step spray pyrolysis process is investigated for the first time in the field of spent lead-acid batteries (LABs) recycling. The spent lead paste that derived from spent LAB is desulfurized and then leached to generate the lead acetate (Pb(Ac) 2) solution, which is then sprayed directly into a tube furnace to prepare the lead oxide (PbO) product by pyrolysis.
A process with potentially reduced environmental impact was studied to recover lead as ultra-fine lead oxide from lead paste in spent lead acid batteries. The lead paste was desulfurized first and then reacted with citric acid to produce lead citrate. Finally, lead citrate was calcined at low-temperature to obtain ultra-fine lead oxide.

Lead-acid batteries, widely used across industries for energy storage, face several common issues that can undermine their efficiency and shorten their lifespan. When a battery is overcharged, excessive current can cause the plates to heat up, leading to faster degradation of the active material. Deep discharges and frequent cycling can
Batteries can heat up during use due to a variety of reasons. One common cause is overloading the battery with too much current or using a device that requires more power than the battery can provide. In some cases, If a lead acid battery heats up while charging, it can indicate a problem with the charging system or the battery itself.
Because lead-acid batteries lose effectiveness due to the effect of “irreversible sulfide”, it is recognized that lead sulfate will gradually condense into small particles along with

Conclusions A research investigation for recycling lead from lead paste in the spent lead acid battery under vacuum has been developed in this work.
The treatment of spent lead paste is essential for the recycling of spent lead-acid batteries. In this study, we propose a facile route for the recovery of lead from spent lead paste by pre-desulfurization followed by low-temperature reduction smelting.
With the wide application of lead acid battery, spent lead acid battery has become a serious problem to environmental protection and human health. Though spent lead acid battery can be a contaminant if not handled properly, it is also an important resource.
There are four main components in spent lead acid battery: polymeric containers, lead alloy grids, waste acids and pastes. Among them, the pastes mainly comprise lead oxide (∼9%), lead dioxide (∼28%), lead sulfate (∼60%) and a small amount of lead (∼3%) (Zhu et al., 2012a).
A typical lead acid battery cell has two plate types, one of lead and one of lead dioxide, both in contact with the sulfuric acid electrolyte as either a liquid, absorbed in a mat (AGM), or a gel.
The lead dioxide (PbO 2) plate reacts with the sulfuric acid (H 2 SO 4) electrolyte resulting in hydrogen ions and oxygen ions (which make water) and lead sulfate (PbSO 4) on the plate. The lead plate reacts with the electrolyte (sulfuric acid) and leaves lead sulfate (PbSO 4), and a free electron.
