I never had luck with rechargeable batteries...tbey always died so fast that i got sick of constantly recharging them. I used rayovac....
I have been burned by rechargeables in the face of a forest fire more than once.
We get $1200 portable radios that can take a rechargeable or they can use a clam shell full of AA's of your choice even rechargeable
Almost no one uses the rechargeables anymore , the best set up we found is packing two clam shells with lithium energizers.....one clam shell last about half the summer on regular use, the rechareables can be half the incident but usually give up after the first couple hours so....unacceptable unless you have five and the don't go out while your directing helicopter drops
These radios keep us alive, make everything happen......next to no one uses rechargeaboes unless they are new but they all eventually switch
Not using one on my gun ever, but I see extreme value if someday you can't roll down to the store to buy AA's
