Preventing old protosound 2 (5 volt) board from blowing?

nycboyOGR Forum Member

Hello everyone, I recently brought a MTH r32 protosound 2 subway set. For a quick summary this set was made around 2003, back when protosound 2 boards came with 5 volts. I've heard that I have to replace the battery every 5 years to prevent the battery from destroying the board. Is that just it? Do the boards just blow up on their own or is it really do to a battery issue? The seller told me he hasnt run this set in 10 years, it was working the last time he used it but obviously the battery is aged now. I have a new mth 9 volt rechargeable battery ready to be installed in it. Do I have to get the mth battery recharge to endure the train does not go bad? All help is appreciated thank you
