Frequently Asked Questions

What does “12000 mWh” capacity mean compared to standard mAh?

Milliwatt-hours (mWh) is a more accurate measure of total energy than milliamp-hours (mAh) because it accounts for voltage. These batteries have a 12000 mWh capacity at 1.5V. For comparison, a standard 10000 mAh NiMH D cell at 1.2V equals 12000 mWh. So, they offer similar total energy to high-capacity NiMH cells, but deliver it at a higher, constant voltage for better performance in high-drain devices.

Can I charge these batteries with a standard NiMH battery charger?

No, you cannot. These batteries charge exclusively via their integrated USB-C ports using the included 4-in-1 cable or another USB-C cable. They are not compatible with traditional NiMH or alkaline battery chargers that make contact with the positive and negative terminals. The charging circuitry is built into the battery itself and requires the USB-C interface.

Are these truly “1.5V” from full to empty like alkaline batteries?

Yes, that’s the key innovation. Unlike NiMH rechargeables that start at 1.4V and drop, these lithium batteries use internal circuitry to maintain a steady 1.5V output throughout their entire discharge cycle. This means devices like gas stoves and bright flashlights will perform at full power until the battery is nearly depleted, then shut off abruptly.

How long does it take to fully charge a depleted battery?

Exact charging time isn’t specified, but it depends on your USB power source. Using a standard 5V/2A (10W) phone charger, a full charge from empty for a 12000 mWh battery would take several hours. For faster charging, use a higher-output USB-C PD wall adapter. The LED indicator will turn green when charging is complete.

Can I use these in devices that require multiple D batteries, like a large radio?

Absolutely. They are ideal for such devices. You can mix and match them with other YUEBVIWIE batteries. Their constant 1.5V output ensures all batteries in the series discharge evenly, which is crucial for multi-battery devices. This prevents the weak-battery effect that can occur with mismatched alkaline or NiMH cells.

What makes them “eco-friendly” compared to other rechargeables?

The eco-friendly claim stems from the 1500-cycle lifespan, which can replace hundreds of single-use alkaline batteries, drastically reducing hazardous waste. Additionally, lithium-ion chemistry generally contains fewer toxic heavy metals like cadmium or mercury found in some older battery types. Their reusability is the primary environmental benefit.
