Charging a lead acid battery at high temperatures can cause serious damage to the battery and even lead to explosions. When a battery is overcharged, it may experience: Reduced Battery Life: Exaggerated use increases internal resistance, reducing the number of cycles performed.
The circuit of Figure 1 protects a lead-acid battery by disconnecting its load in the presence of excessive current (more than 5A), or a low terminal voltage indicating excessive discharge (< 10.5V). The battery and load are connected by a 0.025Ω current-sense resistor (R1) and p-channel power MOSFET (T1).
en gasses to form, increasing pressure inside the battery. Unsealed flooded lead acid batteries use venting technology o relieve the pressure and recirculate gas to the battery. Gassing in excess of venting capacity or malfunctioning vents can ‘boil’ the water out of the ba
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.
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. I bought a cheap 20 Euro unit and it was effectively useless because of this problem. ↩
d lead acid batteries are sulfation and excessive gassing. Both of these can be largely pre-vented by using smart charging technolog full charge.Sulfation, Undercharging, and Battery FailureThe leading cause of battery failure is sulfation. Sulfation is a deposit of lead sulfate crystals on the charging plate
