Alkaline batteries can overheat if exposed to high temperatures or if they are incorrectly charged. Charging non-rechargeable alkaline batteries can cause a dangerous buildup of heat. This overheating can lead to battery leakage. When a battery leaks, it often releases potassium hydroxide, a corrosive chemical that can damage devices or surfaces.
Standard lead-acid cells have a low self-discharge, about 5% per month, so continuously monitoring makes little sense. To measure this I would take a reading with a DMM every few days, and you may need to take readings over a period of more than a

So, if the battery is rated for 120Ah, you can only use 60Ah (50% of 120Ah). This is known as the Usable or True capacity of a battery. Lead acid batteries typically only provide 50% usable capacity from the Ah rating.
At low temperatures, at or below 0 °C, graphite becomes more brittle and hence more susceptible to fracture. 72 Particle cracking is worse for batteries with high Si content NEs, under deep discharge, 73 high currents and with large particle sizes. 74 Manufacturing processes, e.g. calendering, can lead to strain effects and particle cracking before a battery is even in use.
The dry solid polymer battery requires a temperature of 60–100°C (140–212°F) to promote ion flow and become conductive. This type of battery has found a niche market for stationary power applications in hot climates where heat serves as a
The results showed that at 7C, the cell temperature increased by 22.5 °C in 5 min, with a 3.4 °C difference between the battery temperature and the battery surface temperature. In contrast, the battery temperature did not increase by more than 1.5 °C at 1C.

On the other end of the spectrum, high temperatures can also pose challenges for lead acid batteries. Excessive heat can accelerate battery degradation and increase the likelihood of electrolyte loss. To minimize these effects, it is important to avoid overcharging and excessive heat exposure.
The increased internal resistance can limit the overall performance and capability of the battery. 4. Potential Damage: Extreme cold temperatures can cause lead acid batteries to freeze. When a battery freezes, the electrolyte inside can expand and potentially damage the battery's internal components.
In winter, lead acid batteries face several challenges and limitations that can impact their reliability and overall efficiency. 1.
