Hi All,

I have couple of years old Fuji Charger model BK-NH20 and i am using the following NiMh AA rechargeables.

pair of Lenmar - 2400 mAH
pair of Pana - 1600 mAH
pair of Ultra AA - 2300 mAH (from Fry's)

I have been using these batteries with the Fuji charger for the past 3 years. I think this charger came with my Fuji Camera E550 3 yrs back.

Recently i got A570 IS and these batteries doesn't even stay for 60 shots.

Is there a problem with the batteries ? Does eneloop batteries work on this charger ? If i get 2600/2700 mAH batteries, will this charger charge it upto its full capacity ? Does anybody know about this charger spec ?

Greatly Appreciate for your answers, so that i can decide whether i need to get new charger or not.

Thanks

There could be a couple issues here:

1. The cells are simply old and can't hold their rated capacity.
2. The cells need to be put through a refresh mode. Many NiMH chargers on the market today have a refresh mode. Even better is a break in mode which applies a low current charge for a fixed amount of time. This evenly re-distributes the electrolytes within the cell.

Eneloops should work fine in your camera. They have a very low self-discharge rate but the capacity is only 2000 mAh. I have replaced most of my standard NiMH cells with eneloops. You just may want to have an extra set or 2 on hand as their capacity is lower.

If you're looking for a good NiMH charger that has all the functions listed above and then some, consider the Maha Powerex MH-C9000 (http://www.newegg.com/Product/Product.aspx?Item=N82E16817355012&Tpk=C9000)

I am traveling the same road.
I had a Fuji E550 also. I had it for almost 2 years and never worked very well.
I heard it was rated good my Consumer Reports, so maybe I just had a defected one.
I was lucky Sam's Club took it back after so long!
I used the refund of to buy yet another camera from Sam's Club.
Canon A710 IS
This is a great camera, unlike the Fugi. The problem I have is the batteries die on me so fast! I am still learning to use it so maybe if I can turn off the flash when not needed it will help.
Unlike you, I do not have the charger anymore that came with the Fuji, but it looked like a cheap unit. I have a collection of chargers and I just bought a 15 min charger that comes with a car adapter. CH15MNCP-4 so I can recharge the batteries quick while away taking pictures with my new camera.

Does anyone know where I can get info on types of chargers?

The 15 minute charger I have received 7 good reviews, but buyer beware!
6 of the reviews were 5 out of 5 stars
1 of the reviews is 4 out of 5 stars

If you consider the 15 minute charger I have please read the review on newegg titled
“Seriously fast, but cell cycle life won't be as long, though...”

I believe I will only use the older batteries on this charger when I need to charge fast!
I believe two things about chargers.

1) It is better if a charger monitors what it is charging rather than blindly charging it for a specific time.
2) It is better for the battery to charge it slowly overnight, rather than using the 15 min to 2 hour chargers.

I am trying to find a tech forum that tells about the different chargers.
