Panasonic Eneloop Pro.

Pricey but excellent. I have just two sets of AA for the Lightspeed. One set in use, the other set spare, but recharged once the headset starts to warn the batteries are on the way out, or before a continental expedition.

Four years on now.

I have solar panels on the roof, and there is a small accessory that interrogates the inverter remotely to provide generation data. It has eneloop batteries that are charged by a small solar panel on the gizmo.

The batteries are nearly 10 years old now and still going strong.

When you think you've typed PUMP, yet people seem to have seen 'battery/ies'.
