Have a strange problem with Sangean DT200V. Radio is great but I can
only use one type of AA NiMH rechargeable - older Powerizer 2000 MaH.
With newer and higher current AA's (eg., Sony 2500 MaH) radio don't
turn on (The DT200V has electronic on switch). Is there something in
the Sangean that senses the differences in batteries?

Thanks!
