NiMH battery+Charger with refresh feature
I was told that NiMH battery has no memory effect.. or something like this and it can be recharged from 500 to 1000 times as claimed by the manufacturers.
I was at the PC show recently and one young gentleman recommended a charger with refresh feature. Is such feature important to HiMH battery? If you don't have, can we improvise or is there a another way to refresh the batteries.
I have 4pcs NiMH 2300mah, size 'AA'. I have recharged them for less than 100 times but recently I noticed that the performamce had deteriorated to about 50% as compare to when they were new. What can go wrong?
They are 'branded' batteries.

I have owned different type of NiMH batteries ranging fr GP to Sanyo. I am currently using a Sony Charger with Refresh function. It is advisable for you to deplete the batteries before recharging it. Ensure that the batteries are fully charged before they are used, if not you will shorten the life span of the batteries.

Personally i was confused by the refresh function too, not knowing what it would do. I thought that it would be better for my batteries thus bought one with Refresh function.
My experience is that you shld take good care of ur charger too. My charger spoilt within half a year ><, kept changing. This is my third charger, hope it would last.
Ya, shld use discharger to make ur battery last longer~ i always discharge my batteries b4 recharging them.

so far for wat i know, the refresh is meant to discharge the battery before a fresh charge. so it shouldn't damage ur battries. this was wat the shop keeper told me when i brought 4 2300mAh Sanyo AA batt last year. i have been using the refresh function until now its still working like new.

yes, one shld always fully discharged the batteries before recharging to optimize. try to drain it rather than using the Refresh function. My GP batteries have lasted for 2 years.

actually batts are so cheap nowadays and technology is so advanced, is there actually a need to go thru the whole hassle of discharging and monitoring the batt capacity etc?
