Dear all,

 

Does any of you still using NiMH rechargeable batteries?

 

Apparently I find that their charging takes very long and the batteries doesn't really hold charges well.

 

Any good ones to recommend?

U can try those lithium rechargeable...but i think its quite rare coz its very ex [knife] But be sure to avoid NiCD rechargeable...those are really hopeless [shakehead]

 

As for NiMH batteries...be sure to get those 2600 mAh or above, else they're another bunch of hopeless case [shakehead]

Am using the Sanyo Enerloops for all my remotes and Xbox360 wireless controllers.

 

Charging for the Enerloops are around 2hrs and they hold charge pretty well.

I am using GP.

 

GP charger comes many types. 15min full charge, 30 min.... NiMH batteries comes with different capacity. The larger the capacity the more charge they hold, longer to charge.

I brought the 30min full charge a few year back for $100.

 

There are many reason why NiMH cannot hold charge

 

1) Batt faulty

2) Capacity too little and not suitable for digital device (Camera devices especially surge your battery)

3) Temperature, exposure to sunlight

4) improper discharge of batteries (This is the least concern to me)

5) All rechargeable batteries will lose it capacity to hold charge eventually

 

Currently they have a new technology call recyko that promise 85% retention over a year. You may want to consider this. I am not working for GP, just a consumer. hope this helps!

Actually depending on what device(s) you are using, NiMH is quite good and economical. Sanyo Eneloops are hybrids and not your normal good old NiMH batteries. The charge retention is very good so it is good for the devices that you use less frequent. e.g. I have digital camera that uses AA batteries and I have a set of Eneloop batteries inside. In the past, with the normal NiMH, I will often find that when I want to use the camera, the batteries are flat. With Eneloop, it can retain 80% of the charge even after one year so there is less chance of having flat batteries when I need them. For external flash, the NiMH battery has a faster recycle time so you can continue to fire your flash a lot sooner. Alkaline battery take a lot longer to recharge.

 

As for the time it takes to charge these batteries, there are quick chargers that use higher current to speed up the charging time (< 30 min. for 2000 mAh) but with that you will shorten the battery's useful life since the extra current that passes through the battery will generate much higher heat and this is bad for the batteries. The normal charger should take around 6-8 hours to charge a 2000 mAh battery.

NiMH commonly referred to Metal Hydride is old school liao bro. It has got "memory effect", ie you must discharge it fully before charging if not battery life will be shorten.

 

These days, most cellphone, Notebook, and camera batteries are either Lithium Ion based or even better with Lithium Polymer. They don't have "memory effect" and can recharge them as and when you like, and the tendency for self discharge is lower when compared toe Metal Hydride.

I've used GP, Sony and Sanyo. Sanyo seems to last longer than the rest. I use them for my hotshoe flash (photography)

 

Hmm ... how about AAA size?

For standard AA and AAA rechargeable batteries, NiMH is still the mainstream although the hybrids are now getting more popular with its better charge retention characteristic. With the current charger technology, you can find the better ones that can recondition old batteries and can also provide individual trickle charge to ensure the full charge can be maintain.

I got the current charger for Sanyo batteries .... can I use them?

 

Also ... how much are this Sanyo Enerloops? Get from where?

For AA size, yes. But the charge is 3.6V nominal so cannot be used as replacement for your normal 1.5v.

 

But is this thread about normal AA / AAA size batt or we talking in general? [:|]
