MZ-NH1 battery

[sebastianbf]

hello guys.

i'm wondering if the lithium battery of the mz-nh1 has that memory effect thing. I mean: What happens if i charge the battery when there's still some charge on it (let's say half charge). I'm asking this because i'm probably going to buy a mznh1, but i don't think i could buy a spare battery for it. So there are gonna be days that I'll have to charge it when it stills have charge on it. Does this kind of charge ends with a battery with the problem of memory effect , like a NMH battery? or is it true that you can charge lithium batteries while they still have charge? .

Thanks everybody

Lithium batteries do not suffer from memory effect, but when new, are best conditioned by fully draining and charging the battery a few times. The memory effect is something that was common with old Ni-Cad batteries.

For more information regarding types of batteries and the memory effect, see here

No memory effect - but they 'age' relatively fast and become useless after a few years whether you use them regularly or not. Spare batteries might be hard to find in a few years.

I'd disagree, a battery lasts longer with regular use. It deteriorates faster when it sits unused for long times (Months).

You shouldn't have too many issues with the Lip-4WM, but I never let them drain fully too often and I always charge them completely.

The NH1 will charge about 85% of the battey in 60 mins or so, but the last 15% takes another two hours. I read somewhere that it is better in the long term if it also completes the trickle charge phase as well.

I've always had good battery life from my NH-1's, sometimes 2 to 3 days of lots of listening. Would recommend a second battery though if you plan to do recording.

Take care,

If you are going to use it every day then it is best to put it on charge overnight & then take it to use the next day.

Li-ion batteries like to be recharge frequently if they are used regularly. The lower the discharge gets the more damage that happens to the battery, you should get a few years out of it if you chanrge from 30% upto full each time. Constant 0% recharges will give you about 0.5 - 1 year.

interesting. thank you guys.

I've read somewhere (but can't find the source right now) that these batteries do have a fixed lifetime (I believe in the region of 3 or 4 years)and that the amount of use they have has little effect on the length of life.

I wonder if this is why my cell phone manual tells me to keep the battery in the fridge if it's not going to be used for a while (suspended animation?!)

[akijikan]

the science behind that is that chemical reactions are slowed at lower temperature (ie lower engery).

They age slower at low temperatures and 40% charge state. If you constantly top them and store them at high temperatures (common notebook battery situation), they'll die way faster.
