Rechargeable AA Batteries with Charger, 8PCS 2800mAh High Capacity AA Batteries with 8 Bay LED Lights AA AAA Battery Charger (BOANV)
Quick take
This BOANV kit pairs 8 rechargeable NiMH AA batteries (2800mAh) with a USB-powered, 8-bay charger that can charge AA and AAA at the same time. It is a practical choice for households that want to recharge multiple cells without waiting, but buyers should pay attention to AAA contact fit and any heat concerns while charging.
Pros and cons
Pros
- 8 independent charging slots for parallel charging (more convenient than 4-slot designs).
- USB-powered setup for easier charging on the go.
- LED indicators for charging status (red while charging, green when fully charged).
- Designed for NiMH and Ni-Cd rechargeable batteries, with safety features like overcharge and overheating protection.
Cons
- AAA charging may require readjusting the battery contacts, depending on fit.
- Some users report batteries getting hot during charging, which may be a concern for heat-sensitive setups.
- NiMH rechargeable batteries are typically rated at about 1.2V, so they may not match devices expecting 1.5V alkaline behavior.
What buyers think
Buyer-review evidence is mixed but includes a clear theme: the overall combo tends to work as a straightforward rechargeable battery and charger set, with users generally satisfied for day-to-day use. Several shoppers mention the LED/LCD-style status visibility as helpful for knowing when charging completes. At the same time, there is limited-but-relevant concern around AAA battery contact fit, where adjustments may be needed for reliable charging, and some buyers note the batteries can feel hot while charging. One additional theme is voltage expectations, since the rechargeable NiMH cells can be marked around 1.2V, which may matter for devices calibrated for higher alkaline voltage.
What this kit includes and how it charges
This set bundles 8 rechargeable AA NiMH batteries with a multi-slot charger. The charger supports charging both AA and AAA in separate bays, and it is built around independent slots, so you can recharge multiple batteries simultaneously.
Charging status and workflow
The charger uses LED indicators to show real-time charging progress. Expect solid red to indicate charging and solid green to indicate the batteries are fully charged. That simple visual feedback helps reduce guesswork when you are rotating rechargeable cells into devices.
Compatibility and safety features
The charger is designed for NiMH and Ni-Cd rechargeable batteries, and it includes an intelligent IC system intended to detect non-rechargeable batteries to prevent short circuits. It also lists protections against overcharging, overvoltage, and overheating, which can be important when charging multiple cells in one session.
Batteries: capacity, voltage expectations, and real-world fit
The included cells are rated at 2800mAh and use NiMH chemistry. NiMH rechargeables often output around 1.2V per cell, which is different from the 1.5V you get from many alkaline AAs and AAAs.
That difference is most relevant if you are using devices that are sensitive to alkaline voltage behavior (for example, equipment that expects a full 1.5V baseline). For many everyday low-to-medium power uses, NiMH works well once you manage expectations and keep batteries charged.
Pros and cons for common buyer use cases
Best for
- Households that want to recharge multiple AA and AAA batteries at once.
- People who prefer a USB-powered charger for countertop or travel-style charging.
- Users of devices that accept NiMH rechargeables, where voltage difference is not a dealbreaker.
Consider alternatives if
- You need extremely reliable AAA loading without any contact adjustments.
- You are concerned about battery warmth while charging, especially in tight or heat-retaining storage areas.
- Your device specifically requires 1.5V-like alkaline performance.
Verdict
BOANV’s rechargeable AA batteries with charger are a solid “bundle” option if you want an 8-bay USB charger plus a supply of NiMH AAs in one purchase. The main buying caveats are fit and heat, since some buyers report AAA charging can take minor readjustment and that batteries may get hot during charging. If you can work within those limitations and your devices are compatible with NiMH voltage behavior, this kit can be good value for keeping AA/AAA devices powered.

FAQs
Note: The questions below mirror the most common buying considerations for AA/AAA rechargeable battery and charger sets.
Does this charger work with both AA and AAA batteries?
Yes. The charger is built with independent slots intended to charge both AA and AAA rechargeable cells.
Are these batteries 1.5V or 1.2V?
The included NiMH rechargeable cells are commonly marked around 1.2V, so they are not the same as 1.5V alkaline batteries. Check your device’s requirements if alkaline voltage is important.
How do the LED indicators work?
The charger uses LED status colors to show charging state, with red indicating charging and green indicating fully charged batteries.
Is AAA charging reliable in this kit?
Some buyers report AAA batteries may need readjustment for proper contact, so if AAA reliability is critical for your setup, it is worth considering that potential fit issue.
Do the batteries get hot while charging?
Some buyers mention heat during charging. If you are sensitive to warmth or have limited ventilation, monitor charging and avoid enclosing the charger in heat-retaining spaces.
