What is maxium rated operating temperature for Victron AGM/GEL batteries?
Hi @Marek. See the screenshot from the data sheet, anything above 30 degrees C and service life is greatly reduced. If you have a temperature issue it’s best you either try keep them cool or go for a different chemistry, lifepo4 for instance.
Hello, to comment on this. Any lead /acid battery works on the base of a chemical proces. This proces is the same in flooded/AGM/GEL any many other spin-off designs. It doesnt really matter which brand they are as it determined by physics laws that when the temperature goes up, the deterioration gets faster. Of course there are some manufacturers which enhanced usage in high temperatures, but as it always goes when doing these things. If you improve something on the one side you loose out on the other side (which is often less charge speed/efficiency). In general its with the majority of lead acid batteries, that at every 10 C deg average temperature higher then the "normal" 20C deg, you loose about 50% of the lifespan. If there is no way in reducing the ambient temperature you need to realize these are the consequences. Its not all bad news by the way, the battery wil have a high peak current ability, but then again also a lower gassing voltage level which makes charging slower ;-). The cooler you keep the batteries, the longer you will enjoy them !
