Can I use a 9 volt charger for a 6 volt battery?

Question

It's for my daughter's power motorcycle. We don't know whatever happened to the original 6 volt charger, but I have a 9 volt charger that fits and the plug and wanted to know if it's safe to use and will it work.

Serious answers only! Thanks in advance!!! :D

Answer 1

serious answer.... the serioous answer is that you will be over charging and the battery will overheat, it could swell (this is bad!) or it could just burst into flames (this is very bad).

Always use the correct charger!

If you have a car battery charger, and it has a setting for 6v low maint battery - like for a golf cart - you can use this on the AUTO setting for 6v.

Answer 2

Not a good idea - this will overcharge and overheat the battery with potentiallly dangerous results - easy to buy a suitable charger from an electronic store ( Curry's or Argos)

Answer 3

Well, right here my first question would be, what is the required charging rate(current) of the original 6V charger as oppose to the 9V charging rate?  Reason being, if the voltage is not regulated and you load the 9V charger in that the output voltage drops to a value less than 9V, then, if anything, it would be the charger to heat up rather than the batteries.  The batteries, BTW, will not blow up with these values of voltages.  If anything, they will get warm or a little hot.  It is possible to use the 9V charger, but it would diminish its life with constant use if the current charge rate is exceeded beyond the limit specifications.  You would be better off getting the proper charger with the correct charging rate, to be on the safe side.
