Review of Uniross Rechargeable Batteries
I have been using Uniross Rechargeable Batteries for almost four years now; in fact I first bought Uniross Rechargeable Batteries and Uniross Globe Trotter Pocket Charger when I got my first real digital camera.
During this time, I have owned a total of 4 pairs of Uniross nimh batteries, ranging from 2100mah to 2300mah. Out of which, only the first two pairs are now not functioning, because of the numerous amounts of recharges they had to go through to keep up with the number of photographs I take.
Uniross Rechargeable Batteries have provided me top notch performance and even though I have used Eveready and Fuji Rechargeable batteries along with them, I felt Uniross performance was better than the other two.
They have been dependable and have not only provided decent battery backup, they have also managed to retain their charge for weeks, even when left inside the camera.
Overall I have been quite satisfied with them and I am planning to get two more pairs of Uniross 2500mah batteries next month for my upcoming trip.

Nice REview but some numbers would help. Like how many shots per charge for this and how many for competition?
Also you can take this opportunity to review various technologies in rechargeable batteries. How it were Alkaline now they are NiMh and now moving to NiCd.
Am I demanding? Yes! of course, if I do not expect good and deep reviews from you who would I expect it from? Ugesh Sarkar’s fans?
Shots per charge depend on various things, however with the old Kodak CX7430, I was easily getting around ~250 shots from the 2300mah Uniross battery.
Haven’t had the chance to test the capabilities of my new cam (A720IS), but based on the kind of backup I got from the 2100mah Uniross batteries (charged for the first time), I am guessing that number would easily climb to 300-400+, since I must have taken 200+ photos and videos (around half of them with flash) and used the LCD a lot to review photographs and other features, before the low battery sign finally came up.
With regards to others, well 2700mah Fuji rechargeable batteries had a similar performance to the 2300mah Uniross that is when they would work properly.
Eveready 2100mah performed quite well, in fact its performance was similar to that of 2100mah Uniross, but its life got over before the Uniross ones, even though all three pairs were purchased at the similar time. Not really sure if I used it more than the Uniross ones, but overall I did like it a lot.
I don’t really use Alkaline batteries that much, since in the long run they turn out to be expensive (can’t be recharged), never used Nicad since it was old tech and they are known for memory effect.
hey. i am doing a survey on rechargeable batteries used in digital cameras for which i have a questionnaire designed..il be really thankful if you can post it in your blog so that it could be filled in by the anyone interested..thanks
did you use Uniross charger for all batteries or they need to be charged on their specific chargers? have read that chargers make all the difference as far as extending the life of the battery is concerned.
Vikas I use Uniross charger for all the batteries, there is no need for brand specific charger for each battery. Just that the charger ought to be of good quality.
I have one question….how much a pair of uniross rechargeable batteries would cost at present? I had been using one since last year but now I am asked by the camera to change the batteries.
That would depend on the model, but anywhere from Rs. 240-350.
i have purchesed uniross charger with two number of rechargable batterys 2700 MAh from D D Laloo & CO G S road shillong on 21/09/09 with cannon digital camera. But after one month the batterys are not giving satisfied peformence. When it is insert in camera,which show change batters .whereas when put on charge it becomes very hot and not storing charge. Kindly let me know if these two batteries can be replaced as purchased within a very short period.
If you bought them with bill, then you can certainly get them replaced as the legally imported Uniross batteries come with one year warranty.
I don’t agree with your conclusions about Uniross.
I bought AA 2700 mAh Ni-mh and 1000 mAh Ni-mh Uniross batteries with a Uniross charger two years ago. They worked well for a year but when I put them is storage during a training course (cool and dry conditions – inside a tool box)after taking them out they are dead and will not charge (the uniross charger goes Red after a few minutes – which indicates they are not suitable for recharging).
I have tried contacting Uniross but they have not bothered to get in contact with me regarding a solution. Until the company redeem themselves I am very sceptical of their customer service/after sales and am cautious about the lifespan and quality of their products.
How do other brands compare? I’m not in the habit of endorsing a brand until I get evidence of them performing. This hasn’t happened with Uniross i’m afraid
Updated – I have managed to get the Uniross batteries to charge again. This was only possible by using a Sony charger which came with my camera. Now the Uniross charger will charge the Uniross batteries. The Uniross batteries seem to hold their charge as well as they did before they stopped working. So, all-in-all I have some updated conclusions:
Uniross Batteries – 8/10
Uniross Charger – 4/10
Uniross customer service – 0/10
Maybe Uniross could learn how other companies provide a jumper charge in their battery chargers to regain the voltage lost in Ni-MH batteries over time. They would also benefit from answering emails from their customers!
