Ansmann maxE AA-Size recharge. 2100mAh

I got fed up of replacing batteries every 5-6 hours in all our bands Line 6 G50/G90 transmitters. I heard rechargeable batteries had a few problems with the Line 6 gear - such as unreliable battery life estimates and not fitting the battery chamber properly. While these batteries are very slightly larger than standard non-recharging versions they will fit snugly without damage - they just take a bit more wriggling to get out again. In terms of battery life they seem fantastic and have maintained better life even with many recharges per week.

Fairly expensive first buy but then look at how much you save over a few weeks or months and it's fairly economical and probably less environmentally wasteful.
