Temperature: Temperature affects the chemical reactions within lead-acid batteries. High temperatures can accelerate corrosion and gassing while low temperatures reduce capacity and increase internal resistance. The Battery University notes that for every 10°C increase in temperature, the lifespan can decrease by 50%.
One of the key advantages of lithium batteries is their high energy density, which means they can store more energy in a smaller space. This makes them ideal for use in portable electronics, where small size and light weight are important. Lead-acid batteries typically have a lifespan of 3-5 years, while lithium-ion batteries can last up to
Temperature monitoring: Maintain batteries in a cool environment. High temperatures can increase water evaporation and lead to acid stratification. Ideal temperatures are typically between 20°C to 25°C (68°F to 77°F). Lead-acid batteries contain toxic materials that can pollute soil and water if discarded improperly. The Battery Council

To Mike your battery gets hot because of too high a charge rate 7Amps refer to 7Ah, which means 0.35A for 20 hours when new and this is the
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
The lead acid battery maintains a strong foothold as being rugged and reliable at a cost that is lower than most other chemistries. The global market of lead acid is still growing but other systems are making inroads. Lead acid works best for standby applications that require few deep-discharge cycles and the starter battery fits this duty well.
The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them. The most important lesson here is this:
It turns out that the usable capacity of a lead acid battery depends on the applied load. Therefore, the stated capacity is actually the capacity at a certain load that would deplete the battery in 20 hours. This is concept of the C-rate. 1C is the theoretical one hour discharge rate based on the capacity.
A battery at 10.5 - 10.8 volts at rest is probably damaged. A lead acid battery should never be below 11.80 volt at rest. ↩ 'bad' battery protection solutions will just start to oscillate as the battery voltage recovers (above the cut-off threshold) when the load is removed.
Proper temperature management, such as insulation or ventilation during cold storage or hot operation, would ensure optimum lead acid battery performance and prolong its operational life. 11. JIS Standard
