Best NiMh battery for telephone handset -- constant charging? Eneloop Lite?

I have an Ooma phone handset with two NiMH AAA batteries.
They're worn out after a year, and don't hold much charge.

What's the best battery technology for a constant charge situation -- where the handset stays on the charger 24/7 and is used occasionally?
Is there any data or study on this topic?
I'm aware of http://aacycler.com/battery/aaa/ which covers frequent cycling, not constant charging. The phone app "accubattery" attempts to handle constant 100% capacity https://play.google.com/store/apps/details?id=com.digibites.accubattery&hl=en_US&gl=US&pli=1
But for phones.

Hi, I am fully with you. I hesitate to put the rather pricey eneloops into my cordless phones and see them "grilled" by those mostly dreadfull chargers ...

I would assume the eneloop lite would have a longer life - with the sacrifice that the speaking-time is shorter (than with regular eneloops and other).

I would suggest using "high temperature" cells, like the Panasonic BK60AAAH.
Please beware those are flat-top and are rather tricky to get to work in common cordles ...

For myself, I have decided to srap the original charger and put eneloops in my cordless - and take them out once a week and charge in decent charger. :) Of course, quite a hassle.
