Nikon EN-EL20a Rechargeable Lithium-Ion Battery Pack (7.2V, 1110mAh)

Nikon EN-EL20a Rechargeable Lithium-Ion Battery Pack (7.2V, 1110mAh)

Reliable, Genuine OEM Power for Nikon Superzooms and Mirrorless Cameras

When you are deep in the wilderness tracking elusive wildlife or waiting for the perfect moment to capture a lunar eclipse, the last thing you want to see is a flashing low-battery warning. The Nikon EN-EL20a is the genuine, Original Equipment Manufacturer (OEM) rechargeable lithium-ion battery designed to provide safe, consistent, and reliable power for select Nikon digital cameras, most notably the legendary COOLPIX P1000 and P950 superzoom bridge cameras.

Built to Nikon’s exacting factory specifications, this 1110 mAh battery ensures your camera can sustain the heavy power draw required to drive massive motorized zoom lenses and high-resolution electronic viewfinders. Keeping a spare EN-EL20a in your camera bag guarantees you can confidently shoot extended bursts, record 4K video, and use built-in Wi-Fi functions without constantly worrying about finding a wall outlet.

Why You'll Love This Battery

• Genuine OEM Reliability: Built explicitly by Nikon for Nikon cameras, this authentic battery features smart internal circuitry that protects your expensive camera from overcharging, short-circuiting, and thermal swelling—risks frequently associated with cheap, third-party knockoff batteries.

• Memory-Free Lithium-Ion Chemistry: The advanced lithium-ion cells can be charged or discharged continuously without developing the frustrating "memory effect" found in older battery technologies. You can safely "top off" the battery whenever you have access to a charger, regardless of its current charge level.

• The Superzoom Workhorse: This battery is the dedicated power source for Nikon's most extreme zoom cameras: the COOLPIX P950 and the colossal COOLPIX P1000. These cameras require significant power to drive their massive internal lens elements, making a reliable battery absolutely essential.

• Upgraded Capacity: The "a" designation indicates this is the higher-capacity successor to the original Nikon EN-EL20. Providing 1110 mAh (compared to the older model's 1020 mAh), it delivers a noticeable bump of roughly 8% more shots per charge while maintaining the exact same physical footprint.

• Featherlight and Portable: Weighing approximately 1.4 ounces (40g) and measuring roughly two inches wide, this battery adds virtually zero weight or bulk to your kit, making it incredibly easy to carry multiple spares in a small pocket during long hikes.

Technical Specifications

Things to Note

First and foremost, please note that Nikon does not include a wall charger when purchasing this battery individually. It is designed to be recharged using the standard Nikon MH-29 battery charger that was likely included in the box when you originally purchased your camera. If you do not own an MH-29 charger, you will need to purchase it separately.

Secondly, regarding backwards compatibility: Because the EN-EL20a shares the exact same physical dimensions and output voltage as the older, discontinued EN-EL20 battery, they are fully interchangeable. If you own an older legacy camera that natively shipped with the EN-EL20 (such as the original Nikon Coolpix A, Nikon 1 J1, J2, J3, or S1), this newer EN-EL20a will fit and function perfectly, providing slightly longer battery life.

Finally, while inexpensive third-party batteries exist, using genuine Nikon batteries is strongly advised. The massive motorized zoom lenses on the COOLPIX P1000 and P950 draw significant current; many generic batteries fail to deliver consistent voltage under these heavy loads, leading to rapid power drainage or unexpected camera shutdowns mid-zoom.
