    Rechargeable Energizer Batteries - Nikon L840??

    Hi All,

    I am new to Nikon and just picked up a Nikon L840. I bought it to get more into photography (landscapes, outdoors and storms). At the same time I picked up the camera, I also purchased the batteries in the link below. Guy that I dealt with purchasing the camera advised his wife has the same camera and uses these batteries and switches the two sets of these batteries. I was going to purchase lithium batteries but according to the instructions and what is on Nikon's site, it says Ni-MH batteries only. I am assuming that this means not to use lithium.

    So after I got home and just opened the camera box this morning, pulled out the instruction books and it says to only use Nikon branded accessories. I then googled and most people on the Nikon forum site that answered questions concerning this said any "AA" type battery (either alkaline or rechargeable works). I have them charging now but before I put them in, I wanna see if anyone on here uses these types of batteries or knows what to use. According to batteries plus and several other battery sites there are pretty much any battery you could buy that is used with this camera.

    The spec's on these batteries (AA - 1.2v - HR6 w/1300mAh).

    Will these work and be alright without any issues??

    Thanks in advance for the advise.

    Those batteries will be fine.

    I'm sure Nikon would be thrilled if we only bought Nikon-branded acce$$ories.

    Welcome to our Nikonites family! I just recommend not using alkaline for any camera products, simply to avoid leaks and corrosion! My favorite AA or AAA rechargeable batteries are eneloop Pro batteries 1.2v min2450 mAh, but yours should work good too!

    Welcome to the forum.

    The batteries should be OK. Rechargeable lithium AA do not actually exist, because lithium can only be about double voltage. There are non rechargable AA lithiums which can work, but you have to keep buying them (and NiMH recycles faster in a flash). NiMH is the best choice for AA, at least in camera or flash.

    NiMH is good for camera or flash, they handle the high currents much better than alkaline. There are two types of NiMH, the regular type that self discharges while sitting on the shelf a month or two, and have to recharged frequently, used or not. Or there is the low discharge type, which yours says it is, and yours should say still good after a year on the shelf. So you're good to go.

    Re: Rechargeable Energizer Batteries - Nikon L840??

    Thank you Guys,

    I have one more question, the package states that batteries charge in 5 hours. However, the manual that come with it says 8-10 hours and the charger shuts off at 11 hours. I have had them plugged in for approx 8.5-9 hours and the light is still red? Is that normal for the initial charge?

    I went out tonight and while I was out, I picked up the same brand batteries but the power plus, which are 2300 mAh, with that being said they are supposedly pre-charged, but according the Energizer site, it states they can take 13-16 hours for a full charge but the charger, only runs for 11 hours before it has a protection feature that shuts it off, so how exactly does that work?

    Sorry for the newbie questions, the last time I did anything with rechargeable batteries was the old Radio Shack style battery powered RC Cars.

    Is there anything you don't know Wayne? Good grief.

    I do know there are different kinds of chargers.
    Speaking frankly, the link you posted said $15 for four batteries and a charger. So that's a pretty cheap charger. A smart charger costs maybe $30 to $60, less batteries. Maha is a good charger brand.

    The cheap chargers are of a few types. Some just always charge at a low slow rate and never shut off. Some shut off after a constant time period, regardless of the battery size or the previous charge state. Not smart, but if the charge rate is slow enough, this doesn't really hurt the batteries if not overdone too often. Other faster chargers shut off when the batteries get too hot, which implies they are charged and have had enough.

    The good smart chargers have computer circuits to monitor individual battery voltage and state, and shut off individually when the battery is actually full. These will have a status LED for each cell, monitored and controlled individually, what the battery actually needs. This could be up to a couple of hours for a really low AA cell, or less if the battery is not empty.

    Wayne,

    Thank you so much for your help. This is just the batteries, so I am sure when it comes to actually using the camera, the questions are just gonna keep growing!!

    At any rate, I found this charger, same brand you were speaking of, is this one acceptable and will it work with the energizer batteries?

    Maha is a good brand, well valued. That one is $15, 3-4 hours (for a dead battery) is sort of a minimum, fairly slow, but it should do a good job.
    It does say:
    Rechargeable Batteries with full -deltaV Computer Control

    Delta-V is Delta Voltage, which is good - it watches for a specific little voltage peak that indicates full charge, and more would not be helpful. Then it shuts off (to a trickle charge).

    It is a good value for $15, and should run circles around the first one. But a downside is that it only has two status LEDS, meaning it cannot charge just one battery, they have to be in pairs, and the pair is monitored instead of each individual battery. If one is near fully charged and one is very low charge, the pair gets the treatment of the low charged one. This two battery system is common in lesser chargers.

    What I was speaking of sort of starts here:

    Amazon.com: Maha MH-C401FS-DCW INTERNATIONAL Version Smart Charger with Car Adapter: Computers & Accessories

    It has four LEDs, and effectively four chargers which monitors and controls each cell individually, and does just what that one needs. It has a switch to select fast or slow charge, 100 minutes or 4 or 5 hours, assuming near dead batteries that need charge. That one cell will stop fast if the battery doesn't need much.

    Two hours (for a dead battery) is a very reasonable rate for NiMH, called 0.5C. C is the capacity of the battery, and if charged at 1C milliamp rate (2.3 amps for a 2300 mah capacity), it will charge in one hour. Or 0.5C charges in 2 hours. And less time if already partially charged.
    0.5C and 2 hours is a very normal rate for NiMH, if the charger is smart and knows when to quit.

    Wayne, I am going to grab that charger off of Amazon and I am also going to pick up 2 packs of the 2700 mAh batteries.
