3.6V Nimh Replacement Rechargeable Battery Pack 2.1

Great light and you can use the rechargeable battery pack.

-Superb battery life (At 100mw, I get over 8 hours with a pair of rechargeable 2400mh NiMh AA. It will go 14 hours if using lithium AA!) -Excellent sound quality. -Unrivaled reliability. -Smartphone App lets you change settings via dweedle tone. I love the newer, darker finish on them.

This charger can charge up to eight rechargeable batteries. It can also discharge them first, if you want, but I don't think that's at all necessary with NiMH batteries. A small display panel below each battery shows the discharge/charge state of the battery in that slot.

This was exactly what I was looking for. The battery pack is rechargeable and fits in the flashlight. very easy to use.

Very nice headlamp, and it comes with a rechargeable battery pack.

I am very please on this Watson NP-E3 NiMH Battery Pack so far. It't holding up compare to the Higher mAh models I tried in the past also the price was excellent too.

Have 2 of these out, I purchased the rechargeable battery pack and made a big difference

I have had this light for a few weeks at this point and so far I love it. I got the rechargeable battery pack with it and the battery pack lightens the light up significantly. Battery lasts a long time and the light is BRIGHT! Haven’t had to use it in the weather yet but so far I am super happy with this light.

I purchased the MB-D18 Multi-Power Battery Pack after I purchased my D500. Initially I found that I was consuming rechargeable battery packs on the camera at a rapid rate when out shooting, particularly when downloading images via SnapBridge as I was shooting. The MB-D18 Battery pack gave me the flexibility of utilizing different rechargeable batteries that fit the type of photography I was involved with on different days. Utilizing the larger En-El 18c rechargeable battery packs allowed me to go longer without changing batteries at times when battery changes were not feasible. I would highly recommend the MB-D18 battery pack for any photography enthusiast who wants to be able to have greater flexibility in choosing power sources and the ability to shoot significantly longer without changing batteries!

I use this battery as a back-up to my Nikon battery EN-EL4a rechargeable Lithium-ion Battery Pack. I always use my original Nikon battery but if I am out in the field and my Nikon battery goes down after many shots, I then switch to the the Watson EN-EL4A Lithium-Ion Battery Pack as my back-up until I can re-charge the Nikon battery again at home. I find it's more economical using it that way since there is such a big price difference between the Nikon Battery and the Watson Battery. However the Watson battery is a very good battery and reliable in every way.
