[HCARC] Batteries In Handy Talkies

[Gary and Arlene Johnson]

My Alinco DJ-V57T Handy Talkie says in the instructions to ABSOLUTELY NEVER USE rechargeable batteries in their optional battery pack which takes 6 AA batteries.  They say to use 6 disposable ones.  They deny any responsibility of damage to the Handy Talky if rechargeables are used.  Six disposable batteries produce 9 volts.  Six rechargeable ones produce 7.2 volts.  HOWEVER, the rechargeable battery packs you get from Alinco all produce between 7.2 volts and 7.4 volts - the same as the rechargeable AA's.  

Is there something I am missing or is Alinco just trying to play a new Ham for a fool??  I have never heard of not being able to use rechargeables.  Somehow I get the feeling this is like the tag on a pillow that can't be removed under penalty of law.
