I was looking for rechargable batteries of 2000mAh and above but I couldn't find any decent deal in stores so I went for Argos's 4 energizer AA recharg. batteries 2000mAh for £9.99 KNOWING that there must be a better offer around... just a few minutes later I find a Currys, I enter and spot imediately a packet of 4 Energizer rechargable batteries 2450mAh for £9.99. It's the "ACCU" Nh-ME (nickel-metal hybrid) kind which until now has served me well.
In stores I couldn't find a better deal for the Energizer (I'm an Energizer affecionado), don't know online. Hope someone can benefit from this before spending £9.99 on 2000mAh ones in Argos like I did
