Toys “R” Us offers the Duracell StayCharged Rechargeable AA Batteries 4-Pack for $8.99. Add two 4-packs to your cart for $13.48. Opt for free in-store pickup to avoid a $5.38 shipping charge. That’s $1.69 per battery and $7 below the best shipped price we could find. Sales tax is added where applicable. These batteries are pre-charged and last for up to one year when not in use.
Of note, you can get a single pack of the above batteries plus the Duracell AA Size Battery Charger for $13.48 in-cart with free in-store pickup. That’s $6 under the best price we could find for these items separately elsewhere. The charger includes two AA batteries.
