Rechargeable Alkaline Battery Charger

[1x 9 V] For the price of two brand name alkaline 9V batteries you can buy one rechargeable one. The math is clear. I also find it handy to use a fully charged 9V battery for an electronics project or a device that requires 9V. The electronics (but not attached servos) of an Arduino project can be powered with this type of battery. The Watson 9V charger charges two batteries simultaneously.

[4x AAA] I love Eneloop rechargeable batteries, because they seem to last forever and they never damage the devices in which I use them, even if they have gone dead, as often happens with spent alkaline batteries. They also hold a charge longer than even the most powerful alkaline batteries. I use them in every device that I own which is designed to use flashlight batteries, including flash guns, LED flood lights, flash lights, head lamps, image stabilized binoculars, mice, keyboards, portable telephones, and cameras.

[3.7 VDC] The rechargeable battery charges with a usb - cord you already have - genius! No unique separate charger required. Way better than replacing AAA batteries periodically.

[16.8 VDC] This compact battery charger is dependable and gets the job done in a timely manner. It and the rechargeable Nikon battery is the workhorse for photographic success.

[0.185 lb] Great light but getting the rechargeable battery will make you use it so much more often.

[Yes] I love the fact that the battery is rechargeable!

[1.2 V] Best rechargeable battery for flash light.

[LED] Typical for Pelican this light is extremely well made and Bright. I already own several other rechargeable units so I switched to a Rechargeable Pelican Battery as soon as I opened it (Through the two included Duracell 123 in my bag).

[Lithium-Ion] I recently purchased the Energizer LR44 Alkaline Button Cell Battery for a digital thermometer and a few other small devices, and I’m thoroughly impressed. These batteries have exceeded my expectations in terms of longevity—they’ve powered my devices for much longer than expected, especially compared to other brands. The power delivery is stable and reliable, ensuring consistent performance without any unexpected power drops. Additionally, the LR44 size fits a wide range of devices, making it a versatile option. I’m very satisfied with this purchase and will continue to use Energizer for my battery needs!

[0.15 lb] The Exell A32PX 6 volt alkaline battery is a direct fit replacement for the old mercury battery used in the Yashica Electro35 rangefinder 35mm camera. This batteries resuscitated the camera! The voltage is a bit higher than with the mercury, so you may need to tweak your exposure for critical work. With the Electro35 this is easily accomplished by changing the ISO (ASA) on the original Electro35. Frankly, shooting regular negative film didn’t require any change.
