Hey guys.. I was just wondering..

what is the best way to take care of an Ni MH battery? I'm using this type of rechargeable battery for my 360's controller. I've done some readings for my PSP Li-ion battery, and I was suprised to know that for the Li-ion battery (this means our PSP, our handphone, laptop and so forth), it is advisable to NOT DRAINING the battery to empty before recharge, contrary to some beliefs that if we charge our Li-ion battery before it is empty, it would slowly shorten the life span. The explanations were long, but it has something to do with the Li-ion battery having it's own "memory" to actually know how much power it has left and how many powers it needed to charge before it is full. Li ion battery will cut of the supply of power if it detected itself as "full". Hence there is also no such thing as an "overcharged" battery for the Li-ion case.

The only thing that kill our Li-ion (the laptops are the most popular ones here) is the excessive HEAT when we charge our battery.


I was wondering whether the Ni MH battery shares the same traits with the Li-ion.

any experts here in LYN that is willing to share your expertise in this matter?

thanks in advance!

i only know the Li-poly if overcharge or over drain the battery will become expan or blow.

must leave atleast 15% power in it.

Li-poly?

eh? blow? for real? i thought that happens if excessive heat is generated from the battery...

I'm not expert ... but this is what i read ...

Care of New NiMH Rechargeable Batteries

Summary, Li-on battery need to be charge as frequent as possible n to prolong the life, charge before the battery level below 40%. For NiMH, maximum can last 1000 cycles before performance drop, no matter how well it's been taken care of, so charge only when necessary.

BTW, what brand of rechargeable battery u use for ur wireless controller ? How many mAH n how long it last ? If i'm not mistaken, rechargeable battery only 1.2v but normal one 1.5v. Maybe that's explain the battery indicator only show 3 bar eventhough the battery is fully charge.

thanks for the info on Li-ion & NiMH battery guide... good info for laptop/camera/psp/handphone users, coz the battery cost alot to replace...

as for xbox controller batteries... no need to worry so much la, it's user replaceable, no need disassemble or anything.

whether u use rechargeable AA or official microsoft battery pack, i think it's still cheap to replace (less than RM50?) compared to say a handphone or laptop original battery.

u need to add PS3 controller.. hahahaha... battery spoil.. throw away controller.

already implied la, if i write later SDF come hunt me down susah

mAH? it's 3600 mAH..

i dunno how long does it last, but the person who sells it to me told me to charged it for 2 hours..

then I go and play some games for 2 or 2 and a half days before the indicator blinked... (not 2 days STRAIGHT, mmmmm'kay? )

anyone know how to custom made a casing for AA battery for wireless controller that charges through the play & charge kit ?

i'm using a 2100mah only.. lasts for few games.. remembered i played 50cent and COD2 until finish.. battery still not blinking.. and also played few games other than than.

Its actually not advisable to use rechargable AA batteries, coz they come at 1.2V whereas the 360 controller actually needs 1.5V batteries

ehh??

i don't think my battery can last that long.. (then again, i never played 50cent nor COD2 to know how long does it takes to finish both games )

Wow ... that's incredible ... what brand u're using. I just bought GP Powerbank Quick Charger which come with 4 2700mah ... but havent try yet, have to wait for my current battery finish 1st.

You're down dead wrong.

Microsoft advise the opposite -- The controller is actually designed to use rechargeable battery. Specifically the play & charge kit or rechargeable Ni-MH battery.

I do recommened Play & charge kit for accurate battery gauge monitoring & compliancy. Normal battery do show battery gauge. but the gauge will either abesent, inaccurate or static(not moving, always full).

COD2 is longer than COD4 or COD5.

i'm using imedion powerex.

What are you talking about man?

Look at the battery case, it says "Use only alkaline battery".

Dude read properly what i typed, i said rechargeable AA batteries are not recommended, yes Microsoft does encourage the use of their rechargable battery pack.

why u need to do that ? u can buy one for around RM20 including postage ... just do a search in lelong.com.my ... don't know anybody here sell it here or not.

I think I'll leave the "comment" to you all.

Here's the link to validate my claim. Yes, I do said that AA rechargeable is recommended over the Alkaline Cell for a reason~!

Unless you're questioning the validity of wikipedia.....here's the link:-
Play & charge Wiki

Notes taken from the mentioned URL

Battery packs

Battery Pack, Play and Charge Cable and Quick ChargerThe battery pack for the Xbox 360 controller is nickel metal hydride. The pack provides up to 25 hours of continuous gaming for the wireless controller. It is recommended in place of disposable AA batteries (which differ slightly in voltage). It also ships as part of the Play & Charge Kit and as part of the Quick Charge Kit. Third party rechargeable battery pack kits are also available.


Play and charge kit
The Play and Charge kit allows the controller to be recharged while playing a game by plugging the wireless controller into a USB port. The kit also includes the rechargeable battery pack. It should also be noted that the Play and Charge kit allows use of a wireless controller with the battery pack removed, however this can damage the controller [3]. Microsoft currently does not support it to be used as a wired controller, however it does transmit data letting the host know that it is a wireless controller via a Play and Charge kit.[4]; wireless is still used for data communication and the Play and Charge kit therefore need not be plugged into the console itself to function. Any USB port may be used for the player's convenience. The Play and Charge cable also allows automatic pairing of the Wireless controller with the host (i.e. an Xbox 360 or a Windows PC with the wireless receiver).

It should be noted that the play and charge kit batteries are generic 1300mah AA(LR6) nimh cells. Such cells are readily available in 4 packs up to 3,000mah. With 2,000-2,600mah batteries being common.

There have been notable issues regarding this item. Sometimes, after more than six hours, the charge light will still be red, and the controller will not be fully charged. It should also be noted that the black Play and Charge Kits charge faster than the older white ones.
