Uniross battery charger question
royston
25-11-2006
Hi, sorry if I posted this in the wrong place.

I've got a UniRoss Globe Trotter pocket charger rc103719 and I use it to recharge my camera batteries(2300 mAh,came with the charger). I've got a few questions to ask:
1) Will the charger charge batteries of higher mAh and possibly of another company??
2)I've got a mp3 player that uses an AAA battery. Can I use rechargeable batteries?
3) Is a Ni-MH or Ni-Cd battery better and which is cheaper?

Cheers

1. Probably if they are the same physical size and the same voltage. The higher mAh means they will need a bit longer to charge though.
2. Very Probably.
3. Ni-MH are much better don't bother with Ni-Cd's they may seem a little cheaper but the Ni-MH offer much better performance.

Check out http://www.maplin.co.uk to compare prices and specifications.

Ni-Cd's are very slowly being done away with also the higher the mAh also means the longer they are ment to last but take longer to charge as martytoo posted.
Most mp3 players can take rechargeable batteries.
I use this Energizer battery charger http://www.argos.co.uk/webapp/wcs/st...o.x=17&go.y=17 and it can take most makes of rechargeable Ni-MH or Ni-Cd AA/AAA batteries but I mostly use Ni-MH batteries now. Most rechargeable batteries are ment to last up to almost 1000 times before they start to go done and not hold there charge. My sister uses this battery charger http://www.argos.co.uk/webapp/wcs/st...hTerms=9804829
You also cant charge Ni-MH or Ni-Cd at the same time you have to charge one type at a time but you may already know that.

Ni-Cd's suffer from memory problems, that is if you don't fully cycle the battery (discharge then recharge fully) you will probably lose some or all capacity of the battery.

Ni-MH batteries don't, and are therefore much better. I've just started buying lots of rechargeable batteries for everything in the house; as batteries run out and cash permitting will buy a rechargeable set. Even for remote controls. I'm sick of disposable batteries and am concerned long term on the disposal of them in landfill.

When I was a child (I'm only 37) I could probably count on my hands how many devices in the house used batteries, inc. toys. Nowadays, everything seems to have a battery in it!

I now use Ni-MH rechargeable batteries in my digital camara, MP3 player, personal DAB radio and my philips shaver. I still use disposable batteries at times in my remote controls. I got an old Ni-Cd rechargeable battery in the clock in living room that I got when I was in Canada for 8 days last year. Some rechargeable batteries take 5- 6 hours or longer to charge though but are good in the long run.
