12v 18ah Sealed
charging a 12v 18Ah sealed lead acid battery?

i want to charge this battery i have multiple dc wall adapters

i was thinking of using a DC 12v 350mA adapter would this one suit or another be better ?

also how long should it charge without overcharging?

Unless the 12V adaptor has a no load voltage of 13.5V or higher, it won’t fully charge the battery – when charging, the battery voltage will rise and if the supply is not higher voltage than this, no current will flow – no charging.

If the charge rate is limited to 350 mA, you can charge almost indefinately without battery damage – about twice as high will cause the electrolyte to boil out eventually, though.
