Docosapentaenoic acid (DPA) is a long-chain polyunsaturated omega-3 fatty acid. It is an intermediary in omega-3 fatty acid synthesis, occurring between production of more well-known omega-3s: EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid).
Battery ventilation is vital â summary . There are no legally enforceable (RV) standards in this area. This article can thus only state that battery makers stress battery ventilation is vital. Some explain why. There is little or no risk if batteries are housed in well vented enclosures. With sealed batteries the risk is not high. It exists however if they are within (say) a closed bed base that traps gas. Eliminating this risk consist of little more than cutting slots, or drilling holes. So why not do it?

The reason they say to do this is because laptop batteries lose their charge over time and they don't know how long the battery sat in a warehouse prior to being used. All laptop batteries contain electronics in them that prevent over charging once the battery reaches 100%. If the battery has sat for a long period of time the calibration of the laptop battery's remaining power estimate will be off and could stop the charging battery before it is completely fully. This is why most instruction manuals say to charge over night to 100% then run it down to 5%-10% and then charge it again.
