- zabzonk 5y agoAren't most lead-acid batteries sealed? The one in my mobility scooter certainly is.
- CameronNemo 5y agoI imagine many are. But in small spaces with poor ventilation (e.g. vehicle interiors) that might not be enough. The sealed batteries still have a vent for the gas to leak (in a controlled manner). https://electronics.stackexchange.com/questions/175649/are-sealed-lead-acid-batteries-safe-to-use-indoors#191938 https://electronics.stackexchange.com/questions/175649/are-s... But besides that, li-ion batteries have more energy per weight, are more efficient at storing energy, and can be discharged to a farther level without negatively impacting the battery.
