Query on Uniross battery charger

[hacket]

Finally, got my self a basic P n S digicam few weeks back, its a Canon Powershot A470. Cam was bundled with 2 pairs of batteries(both rechargable ones). A pair Panasonic 2100mah batteries and a pair of Uniross 2100mah batteries which bundled with the Uniross Battery charger RC104423.

Problem started when I tried to charge the panasonic pair for about 12 hours, its was a mess, both batteries outer cover opened up and started to leak!
The charger had water like liquid all over it, even after 5 days am still finding traces of liquid coming out. Now, how do I get rid of it? I don't have the right tools to open up the charger nor am a electronics punter to fix it.


But, luckily the charger still works!am able to charge the other pair of batteries.

Now,few thing I want to know:

• What is the average time to charge a pair of 2100mah batteries? The manual on the charger says 16 hours for 2100mah.
• What liquid is it am I finding on the charger?(pic attached)
• Has anyone faced similar problems?
• Suggest me a pair of batteries.

I had faced a similar problem with the Uniross charger overheating and the plastic getting deformed due to the heat. The batteries did not leak though. It was a set of 4 batteries and a Uniross sprint charger. I promptly took it back to the store where I had purchased it from and got a replacement. Mine is the Sprint quick charger and charges a pair of 2100 Mah batteries in 2 hours. The charging time differs depending on the charger you are using. Go by the manual.

Did you by any chance happen to use the charger on backup power from a non sine wave inverter? That's how the problem happened in my case. Suggest you take it back and get it replaced.

AFAIK, Canon provides one pair of rechargable Uniross batteries and another pair of Normal Panasonic Alkaline Batteries (non-rechargable).

Did you say you charged the Panasonic ones? Make sure they are really rechargeable and not the normal alkaline.

• What is the average time to charge a pair of 2100mah batteries? The manual on the charger says 16 hours for 2100mah.
  The battery has a rating (probably something which reads x hours at y mVA) printed on it, and the charger has the output rating (probably simply mVA).. some simple math should get you there.
• What liquid is it am I finding on the charger?(pic attached)
  Probably out from the alkaline battery
• Has anyone faced similar problems?
  hmmm.... me not really
• Suggest me a pair of batteries.
  Uniross is good. Recently bought a pair of Sanyo due to unavailabiity of Uniross at my place.. i think they are equally good

Thanks for clearing my doubts guys.

@Salil,there was no power cuts when the batteries were charged. Anyhow, I'll take it back to service guys and get it fixed/replace/cleaned.

@Rx3, yes Panasonic ones and it appears am wrong about them, nowhere on the battery says it is rechargeable and I put them up for charging damn!

Time to buy a new pair.

Lol, Uniross battries and chargers are quite good though the one that you have now takes too long i.e. any where from 16-36hours (depending the battery capacity). You can easily get a Uniross 4-8 hour charger + 2 pairs of 2100/2300/2500mah rechargeable batteries for around 1k (they come in a package).

Has anyone used/compared the 2100 and 2500 mAH batteries? Is there a significant difference?

[Yogesh Sarkar]

Have compared the 2100 with 2300 and it seems 2300s take around 20-25 pics more.

Yup, i had both. And i prefer the 2100. 2500 does take few more pics. but has a lower life and poor low temperature performance compared to the 2100. When it comes to performace in freezing temperatures, my 2500 Sanyo was the worst.

Thanks, Salil. I sort of feel suspicious of some of the 'new' products.
Think I'll stay with my Panasonic & Sony 2100 mAH batteries for now!
