I've noticed with some rechargeable batteries (Sanyo especially) they run at 1.2v, is that the case with these or are they at the normal 1.5v?

    All NiCD and NiMH batteries (including these) are "nominally" 1.2V (but can reach 1.45-1.6V fresh off the charger). Most disposable batteries are 1.5-1.6V when new but are down to 1.2V around when they're halfway used at moderate power drain, and earlier for high-drain devices. Any device that will not work down to 1V (per battery) isn't giving you your money's worth out of alkalines. Lithium AAs are different yet again, running 1.6-1.7V, which can be good or bad depending on the device (it'll burn out incandescent flashlight bulbs early).

  • For rechargeable AA batteries, 1.2 V is the standard. Since Apple is saying the charger will work with other brands of NiMH rechargeable batteries, it seems reasonable to assume that they are following the standard. In any event, Apple is making this product specifically to power its own devices, and even if they're "only" 1.2 V, they will be fine for their intended uses.

    Most modern electronics are capable of dealing with the lower voltage of rechargeables, but if you have some other product that absolutely requires the full 1.5 V of standard non-rechargeable batteries, you would do well to simply use those instead.

  • All NiMH batteries are 1.2 volts. They work fine with devices that only require a few batteries like Apples wireless keyboards and mice but they may not work with devices that use more batteries. I have tested NiMH batteries in a device that requires 3 batteries and it works fine. If you need 1.5 volts per batteries, try getting rechargeable alkalines.

  • These are AA NiMH batteries, which are all 1.2 volts.
