Battery Charging Max

AI Thread Summary

Charging a 170Ah sealed lead acid (SLA) battery at 32A, which is approximately 0.19C, is generally considered safe, as it falls within the recommended charging range of 0.1C to 1C. However, it's important to ensure that the charger is specifically designed for SLA batteries to avoid potential damage. Charging at higher rates can lead to overheating and reduced battery lifespan if not managed properly. Users should monitor the battery temperature and voltage during charging to prevent any issues. Overall, while 32A is acceptable, caution and proper equipment are essential for safe charging.

What is the max current for a rapid sealed lead acid battery charger?

Most recommend 0.1C up to 1C where C = Ah rating. I have a max 30-32A regulated 13.8VDC power supply and the battery is 12V, 170Ah. Would charging the battery at the max 32A damage the battery?

Thread 'Query on Isentropic relationships (such as PV^gamma = constant)'

Hi all, I have a question. So from the derivation of the Isentropic process relationship PV^gamma = constant, there is a step dW = PdV, which can only be said for quasi-equilibrium (or reversible) processes. As such I believe PV^gamma = constant (and the family of equations) should not be applicable to just adiabatic processes? Ie, it should be applicable only for adiabatic + reversible = isentropic processes? However, I've seen couple of online notes/books, and...

Thread 'Dry sump pump issue'

I have an engine that uses a dry sump oiling system. The oil collection pan has three AN fittings to use for scavenging. Two of the fittings are approximately on the same level, the third is about 1/2 to 3/4 inch higher than the other two. The system ran for years with no problem using a three stage pump (one pressure and two scavenge stages). The two scavenge stages were connected at times to any two of the three AN fittings on the tank. Recently I tried an upgrade to a four stage pump...
