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?

A battery charger, or recharger, is a device used to put energy into a secondary cell or rechargeable battery by forcing an electric current through it. The charging protocol depends on the size and type of the battery being charged. Some battery types have high tolerance for overcharging and can be recharged by connection to a constant voltage source or a constant current source, depending on battery type. Simple chargers of this type must be manually disconnected at the end of the charge cycle
