Why I'm Never Buying Regular Batteries Ever Again

Product Summary: Rechargeable Batteries

The video argues that modern rechargeable AA batteries are generally a better-value, less wasteful alternative to disposable alkaline batteries. The host focuses on Amazon Basics and Eneloop rechargeables, compares them with Duracell alkalines, and recommends a Bonai charger.

Main Findings and Comparisons

• Price: At the time of the video, a pack of eight Amazon Basics rechargeables cost about $4 more than eight alkalines—roughly 50¢ extra per battery. Eneloop and Duracell rechargeable cells cost around $1 more per battery than alkalines. The host says the added cost can be recovered after very few recharge cycles.
• Capacity: The video cites 2,500 mAh for Duracell rechargeables and 2,000 mAh for Amazon Basics rechargeables, compared with about 1,500 mAh for the Duracell alkaline batteries used as a reference. The host notes that capacity figures alone do not tell the whole story.
• Independent tester results: A test by flashlight-focused YouTuber LumenCraft reportedly found that Eneloops lasted nearly three times as long as alkalines and maintained voltage more steadily. Amazon Basics rechargeables lasted slightly longer in that test, though with less even voltage.
• Host’s flashlight test: The host compared Amazon Basics rechargeables with newer Duracell Power Boost alkalines in two identical flashlights. Both were still producing light after 12.5 hours. Duracell had a small brightness advantage near the end, but the overall result was close. The host notes that Eneloops could make the comparison more favorable to rechargeables.
• Voltage: Alkalines start at about 1.5 V, but their voltage falls as they discharge. Some devices stop working when it drops near 1.1–1.0 V, leaving some capacity unusable. NiMH rechargeables are 1.2 V but tend to hold their voltage more steadily, which can let devices use more of their capacity.
• Storage and leakage: The host says rechargeables are less prone to the leakage and corrosion associated with alkaline cells. Although both types may have similar stated shelf lives, the host considers rechargeables more dependable in practice and cites viewers who reported using them for over ten years.

Charger Recommendation

The host’s preferred charger is the Bonai 18-bay universal charger, priced at about $30 in the video. It can charge AA, AAA, C, and D batteries and has a display showing each cell’s charge level. The host considers its broad compatibility and price major advantages over simpler chargers, which may support only AA batteries.

Pros

• Lower long-term cost after recharging.
• Less waste than repeatedly buying and discarding alkalines.
• Strong capacity and, in some tests, longer runtime than alkaline batteries.
• Rechargeables can maintain voltage more consistently.
• Less concern about leaking cells.
• Broad choice of chargers and rechargeable-cell formats.

Cons and Limitations

• Rechargeables require an upfront purchase and a charger.
• Standard NiMH cells provide 1.2 V, so they may not suit rare devices that specifically require 1.5 V.
• Newer, more expensive alkaline batteries performed close to Amazon Basics rechargeables in the host’s flashlight test, with a slight brightness advantage at the end.
• The video notes that 1.5 V lithium-ion rechargeable batteries exist for devices needing that voltage, but describes them as expensive.

Verdict

The host recommends switching most household devices—such as toys, remotes, and controllers—to rechargeables. They favor Amazon Basics for everyday use and Eneloops for devices that need longer-lasting power, while keeping disposable batteries only for uncommon devices that require 1.5 V. The conclusion strongly favors rechargeables for cost, convenience over time, and reduced waste.

Different Perspectives Mentioned

• Host: Became convinced through price research, published testing, and a personal flashlight comparison. Recommends Amazon Basics, Eneloops, and the Bonai charger.
• LumenCraft: The host cites this tester’s controlled battery measurements, which showed strong runtime and voltage results for Eneloop and Amazon Basics rechargeables.
• Jake, the host’s husband: Mentioned as skeptical, but no separate test results or detailed opinion from him are included.
