Left-Right Solder and changing a new battery

[Rookie Deluxe]

Hello everyone.

Please explain to me, how do I know which one is left channel and which one is right channel, before I decide to solder?

On both jacks, one is longer then other, is the longer meant for Left or Right?


I need also to change the battery on my Sony Effect processor. Never done that. Any links how this is done?

Any particular limit of how much heat can battery handle while trying to put new?

Is this too difficult? Not sure how much soldier is needed to look clean like this original battery inside.

Thanks guys

Tip is left, so whichever solder lug is connected to the tip.... Use a multimeter to see which one is connected to which contact, but yeah, probably the longest one is left.

Short answer: do not solder directly to a battery. Buy a battery with solder tabs welded on if you have to, then solder to those. However, if there's space, you're better off buying a battery holder for a similar size battery, soldering that to the board, and snapping the battery into the holder.
