Replacement batteries ( NP-400 )

Well , they don't seem to make things like they used too .
It seems that my Minolta NP-400 for my Dynax 7d , DiMage A1 and A2 don't seem to be holding there charge as well as they used too . I'm not sure why , it's not like there even 20 years old yet !

So I think it's time to get a couple of fresh ones .

Minolta only want's to sell me a photocopier , Pentax also used this battery ( D-LI50 ) in their K10d and K20d , but don't list it anymore ....

So third party it is .
I've had a look on Hahnels website , who I know supply decent batteries , they don't seem to do it anymore , so off to the unknown Chinese offerings .


Most of what I see either doesn't even state a brand or I have never heard of them before . they are quite possibly all from the same factory anyway .

So does anyone have a suggestion of any make that better than another ?

I've seen one brand (DSTE ) on Amazon with a charger , who seem to advertise quite a few .
never heard of them , but at least they use a brand name !


DSTE 2 pack batter and charger

Any thoughts ?

Cheers Addy .
I did a search for Jupio branded ones on ebay , U.K , EU and worldwide , but nothing came up .
I guess it is pretty much pot luck these days , I doubt they'll last as long as the original Minolta's though .

I have a Jupio battery for my Canons, it is a fine battery. The Minolta original battery is 1500 mAh, the Jupio is 1450 mAh. So, comparable.

Some places selling the Jupio:

No experience with Jupioshop, the others are reputable shops.

Came as a 2 battery + charger kit much like that DSTE kit, even the same kind of USB charger that caught me out a tad. So I've added an old Iphone charging block to the kit so I can plug it into the wall.

It's the USB charger that caught my eye .
I have plenty of the mains chargers , but I fancy a usb charger for when I'm away in my campervan to charge them up via a powerbank or the vans 12v system.

Saves setting the mains inverter up .
