Today only, until 9 pm ET, Pennywise offers the Rayovac AAA I-C3 15-Minute Rechargeable Battery 12-Pack for $8.99. Coupon code "dealnews1" cuts it to $7.99. With 1-cent for shipping, that's tied with our mention from three weeks ago and among the least expensive rechargeable AAA batteries we've seen. These batteries purport to offer a charging time of 15 minutes or less. Note that they're bulk packaged and will arrive without the Rayovac I-C3 charger, which enables 15-minute charging times. These batteries will arrive branded as either Rayovac or Noma.

Please note that this merchant does not offer a return policy.
