Question Details

Do you need to solder the new battery in for it to work ? or can you just set it in between the two metal bands and that satisfactory and will it be able to recharge itself when it’s in the ignition ?

You didn’t offer the year that was applicable to my vehicle. It’s a 2001 740iA

If the old battery is not soldered don't solder the new one. The only battery that is soldered is the rechargeable one.
