Charging at high temperatures can lead to reduced battery life, while charging at low temperatures can result in incomplete charging. The optimal charging temperature range varies depending on the type of battery chemistry. For example, lead-acid batteries should be charged between 50°F and 80°F, while lithium-ion batteries should be charged between 32°F …
Only at very high ambient air humidity (above 70%), water from outside the battery can be absorbed by the hygroscopic sulfuric acid. In summary, the internal temperature of any lead-acid battery (flooded and AGM) should not exceed 60 °C for extended time periods frequently to limit vaporization. 2.1. External and internal heating of the battery
Similar with other types of batteries, high temperature will degrade cycle lifespan and discharge efficiency of lead-acid batteries, and may even cause fire or explosion issues under extreme circumstances.
Thermal management of lead-acid batteries includes heat dissipation at high-temperature conditions (similar to other batteries) and thermal insulation at low-temperature conditions due to significant performance deterioration.
1. Introduction The main tasks of automotive lead-acid batteries are to ensure the cranking of the internal combustion engine, to buffer electrical energy in vehicle operation and to supply the electrical system when the engine is off. These functions are covered by SLI batteries (starting, lighting, ignition) .
Despite this, while thanks to the low cost and high reliability, along with the capability of supplying high surge currents, it is attractive to use lead-acid batteries in motor vehicles (to provide the high current required by starter motors) and uninterruptible power supply (UPS) systems .
High temperatures may accelerate mass degradation. Loss of inner surface of negative sponge lead electrode (to be prevented by expanding additives in the negative active mass)—resulting in a degradation of high-rate capability. Corrosion of positive grid and conducting elements (dependent on the alloy)—leading to higher internal resistance.
Charging at high temperatures can lead to reduced battery life, while charging at low temperatures can result in incomplete charging. The optimal charging temperature range varies depending on the type of battery chemistry. For example, lead-acid batteries should be charged between 50°F and 80°F, while lithium-ion batteries should be charged between 32°F …

As shown in Table 2 and Figure 1, the SIND 06 920 battery performed extremely well when subjected to the IEC 61427 test protocol. This is a particularly harsh test because not only does it subject the battery to partial state of charge (PSOC) cycling, but is done at an elevated temperature of 40°C ± 3°C. Because of these two factors (PSOC ...
