    Watson EN-4 reviews

    EN-4 Ni-MH Battery Pack (7.2V, 2000mAh) is rated 4.0 out of 5 by 16.
    Rated 4 out of 5 by from Better than some I bought this battery for my Nikon D1H camera. The D1H is known for poor battery performance, a reputation well deserved in my opinion. Several of the generic batteries I've tried from one of the auction sites failed miserably, giving me only 20-30 shots before Nikon's battery indicator bar went to low. After receiving this battery I refreshed the battery 3 times prior to use based on recommendations found on the internet. I'm happy to report the first time I used this battery it gave me 185 shots before the battery indicator went to the low position. Still not great, but much better than any of the other generic batteries I've tried. My personal opinion is the real reason for poor battery performance is the D1H (at least MY D1H). In the meantime, this is the best battery I've found.

    Rated 5 out of 5 by from Best Value for the D1 Series The only Nikon camera I ever buy after-market batteries for is my D1x. I've owned 4 of them over the years, and for my use the Nikon batteries just aren't worth the asking price. I had one of these and liked it. Now I have a back-up. Even for the Watson batteries I follow the old full charge, then full discharge breaking in even for these batteries. (Do that 3 times before ever using the batteries-may take a couple of days.) It should prolong their life. Recommended. product.

    Rated 4 out of 5 by from Works but need upper body strength to charge I purchased two of these batteries, and as stated in other reviews, the plug is extremely snug when hooking up to the Nikon OEM charger (MH-16). I had to really force the plug in on both batteries. I have two charging units, and both were very difficult to insert. Once properly conditioned with the three refresh cycles, the batteries work in my D1h's and D1x as they should. Recommended with the reservation that you have good upper arm strength to connect the charger.

    Rated 5 out of 5 by from Watson EN-4 Ni-MH Battery Pack (7.2V, 2000mAh) Fits in Nikon D1 camera perfectly. Charges like original battery using Nikon original equipment charger. Charger cord connection is tight and one needs to be careful in plugging it in the battery but it works just like original Nikon equipment. I did use the battery charger to refresh the battery before I used it.

    Rated 5 out of 5 by from EN-4 battery for Nikon D1x I use my EN-4 on my Nikon D1x for B&W bodybuilding photography. Charges quickly & no downside! I'm ordering another. I've had 3 other batteries since the beginning of the year. All died a quick death except this one! Send me another for backup:) Easy to order, quick to deliver! Thanks ya all.

    Rated 1 out of 5 by from Nikon Charger plug couldn't fit! I had to return this product because my Nikon Charger plug couldn't fit into the battery plug. It looks like it will fit but the charging slot on the battery was to small. I have purchased non-Nikon camera batteries in the past with no problems. Perhaps this was a badly produced factory batch.

    Rated 3 out of 5 by from Good at holding a charge. Charging port is too tight Have bought two of them this year to keep old cameras alive. They hold a good charge (two refresh cycles before first use). The plastic opening for the charging port is too small, making the Nikon MH-15 and MH-16 charging adapters hard to attach.
