Question 1

Are these batteries compatible with my gas stove, water heater, or other continuous-drain devices?**

Accepted Answer

Generally yes—the constant 1.5V output works well with electronic igniters and control boards. However, some Reddit users report that older gas stoves expecting a voltage drop may trigger false “low battery” warnings. If your device has digital displays or sensitive electronics, these are an excellent upgrade. For purely mechanical devices, alkaline batteries may still be more predictable.

Question 2

How long does one full charge last compared to regular D batteries?**

Accepted Answer

In typical use (toys, flashlights, remotes), expect 2-4 hours of continuous runtime per charge. The 9000mWh rating is *total energy*, but its real-world performance varies: for high-drain devices like motorized toys, many TikTok users found they last about 60-70% as long as premium alkaline D cells. For low-drain devices (clocks, thermostats), expect 6-12 months of use. They recharge fully in about 2-3 hours via USB-C.

Question 3

Do these batteries leak or damage devices if left unused for months?**

Accepted Answer

No—this is their biggest advantage over alkalines. Lithium-ion cells don't corrode or leak, even when left in devices for extended periods. Many users leave them in seasonal decorations or emergency flashlights for 6+ months with zero issues. The built-in protection circuit also prevents overcharging, short-circuiting, and overheating.

Question 4

Can I use any USB-C cable to charge them, or only the included one?**

Accepted Answer

You can use any standard USB-C cable, but the included 2-in-1 cable is designed for tight battery compartments—it's shorter and has a low-profile connector. Some users on YouTube noted that thicker phone cables may not fit flush in certain devices. The batteries themselves accept standard USB-C power, but for best results, use the included cable for the first few charges.

Question 5

Will these work in a device that requires 1.5V AA batteries?**

Accepted Answer

These are D-size batteries—they're physically larger and won't fit in AA slots unless your device has an adapter sleeve. However, Artman also makes AA versions of this same lithium technology. If your device *expects* D cells (like a high-power flashlight, gas stove, or large toy), these are perfect. For devices requiring multiple D cells, pair them and they'll last through hundreds of recharge cycles before losing capacity.
