Buy IKEA rechargable ones....buy the charger.
I stop buying batteries for more than a year now after using IKEA Laddas (brown ones will do). Initial cost 'slightly' higher, but long term I guess cheaper.

Not sure about clocks, but I use them for my mouse (never turned off at 2000DPI mode) and I spend 12 -16 hours a day on computer. I get a couple of months (2/3 months) of usage.
The IKEA Ladda (both white and brown) are made in Japan and perform better than Energizers or even Eveready Golds IMO.

Also my shaver, but rarely use that also and it holds charge well.

Look up youtube for IKEA Ladda tests.

It's been 3 years now. Charger working fine (the Ikea Vinninge RM 12.90 with 2 slots)

I now have 16 AAA and 20 AA laddas (the old ones are those peach/brown kinda colour, new ones are light blue). The first batch ones (that i bought 3 years ago) are still being used in remotes and mouse. Almost no significant degradation in both charger and batteries.

Edit: For RM12 charger to work 3 years, I guess even if spoil can get a new one
