Energizer rechargeable batteries are made by Energizer Holdings Inc, the same company that produces Energizer alkaline batteries, but the rechargeable NiMH (nickel metal hydride) cells are manufactured at different plants than the standard AA and AAA alkaline lineup.
Energizer Holdings has operated as an independent public company since it spun off from Ralston Purina in 2000.
While Energizer alkaline batteries trace much of their household production to the companys Bennington, Vermont facility, the rechargeable NiMH line is produced through a mix of Energizer owned manufacturing and contract manufacturing partners in Asia, reflecting how rechargeable battery cell chemistry requires different equipment and processes than disposable alkaline cells.

Energizer Holdings And The Recharge Product Line
Energizer markets its rechargeable batteries under the Energizer Recharge name, covering AA and AAA rechargeable batteries aa formats along with chargers sold as complete kits.
The company has offered rechargeable NiMH batteries for decades, positioning them as a cost saving and lower waste alternative to single use alkaline cells for high drain devices like game controllers, flashlights, and cameras.
Energizer Holdings is headquartered in St Louis, Missouri, and in 2019 the company completed its acquisition of Spectrum Brands battery and portable lighting business, which added the Rayovac brand to its portfolio alongside Energizer, giving Energizer Holdings two major battery brands under one corporate roof.
More on the deal is available in Energizer Holdings investor materials.
NiMH Cell Chemistry And Where It Is Produced
Nickel metal hydride cell production is technically distinct from alkaline battery manufacturing.
NiMH cells require different raw materials, including nickel and hydrogen absorbing alloys, and are typically produced at specialized facilities in Asia, including China and Japan, where much of the worlds NiMH cell capacity is concentrated, a pattern documented by the International Energy Agency.
Energizer sources and finishes its Recharge line through this global rechargeable battery supply chain rather than at its Tennessee or Vermont alkaline plants.
This mirrors the broader rechargeable battery industry, where even well known consumer brands like Duracell and Panasonic rely on specialized NiMH and lithium ion cell manufacturers rather than producing every cell chemistry in house.
Energizer Recharge Ratings And Capacity
Energizer Recharge AA batteries are commonly sold in capacities ranging from around 1300 mAh to 2300 mAh depending on the specific product line, with higher capacity cells intended for high drain devices and standard capacity cells intended for everyday electronics like remote controls and clocks.
The company also sells rechargeable aaa batteries in its Recharge lineup, along with universal chargers capable of handling both AA and AAA sizes, which is a common configuration across the rechargeable battery market.
Some Recharge kits include a fast charger that can top off a set of four AA cells in about an hour, while base level chargers may take several hours for a full charge, so shoppers who need quick turnaround for devices like game controllers should check the specific charger speed before buying rather than assuming all kits perform the same.
Environmental And Cost Considerations
Energizer promotes its rechargeable batteries as a way to reduce landfill waste, since a single NiMH cell can typically be recharged hundreds of times before its capacity degrades significantly.
This makes rechargeable batteries a meaningfully lower cost option over the long run for households that go through large numbers of disposable batteries.
The Environmental Protection Agency encourages recycling both disposable and rechargeable batteries rather than discarding them in household trash.
How Energizer Recharge Compares To Other Rechargeable Brands
Energizer competes directly with Duracell, Panasonic Eneloop, and various private label rechargeable batteries sold by retailers.
Shoppers who want the standard alkaline version of this brand can also read our guide to who makes Energizer alkaline batteries.
Capacity, self discharge rate, and charger speed are the main differentiators shoppers compare, and Energizer Recharge cells generally perform in line with other mainstream NiMH offerings on the market.
Quality And Trustworthiness Of Energizer Rechargeable Batteries
Energizer Holdings has decades of battery manufacturing experience and a long track record with its Recharge product line, giving the rechargeable batteries a level of quality assurance backed by an established public company.
Because the NiMH cells are sourced through specialized rechargeable battery manufacturers rather than built at Energizers own alkaline plants, buyers are effectively getting cells built to Energizers specifications by manufacturers who focus specifically on rechargeable cell chemistry, which is generally seen as a strength rather than a weakness in the rechargeable battery market.
Where To Buy Energizer Rechargeable Batteries
Energizer Recharge batteries and chargers are widely available at grocery stores, big box retailers, drugstores, and online marketplaces, typically sold in individual packs or combined with a charger as a starter kit for households switching away from disposable alkaline batteries.
Buyers should check the printed mAh rating and manufacture date on the package, since NiMH cells slowly lose capacity in storage even before their first use, and fresher stock generally performs better right out of the box.
Frequently Asked Questions About Who Makes Energizer Rechargeable Batteries
Are Energizer rechargeable batteries made in the same factory as Energizer alkaline batteries?
No.
Energizer alkaline batteries and Energizer Recharge NiMH batteries use different manufacturing processes and are generally produced at different facilities, since rechargeable cell chemistry requires specialized equipment.
How many times can an Energizer rechargeable battery be recharged?
Most Energizer Recharge NiMH batteries are rated for hundreds of recharge cycles, though actual lifespan depends on usage patterns, charger quality, and how deeply the battery is discharged between charges.
Is Energizer Recharge better than Duracell rechargeable batteries?
Both brands offer competitive NiMH rechargeable batteries with similar capacity ranges.
The better choice often comes down to price, included charger features, and personal brand preference rather than a significant performance gap.
Independent battery testing groups generally find that most name brand NiMH cells released in recent years perform within a similar range of each other, so household use cases like remote controls or wireless mice rarely reveal a dramatic difference between top rechargeable battery brands.
Does Energizer own Rayovac?
Yes.
Energizer Holdings acquired the Rayovac and Varta battery and portable lighting business from Spectrum Brands in 2019, adding Rayovac to its brand portfolio alongside Energizer.
