Battery Type/life

[Jaz]

I just got my Blu+ and having tested a few diffrerent brands of batteries I was just wondering whitch one's are the best.

I relise after just a few days that the gp32 takes alot of juice, so for the more experianced gp users, could you tell me which you belive to be the best batteries and what is the average time you get with them?

Cheers!

I use rechargeables, Uniross 1300 and they last pretty well...

 

[jonjandran]

I use Rayovac 15 minute rechargeables. 2300mA .
They seem to last forever. The last much longer than regular Duracell or Energizer. I even bought some other 2300mA rechargeables and they last only half as long.

Ive got some Durecel 2050mah 15 minute recharge, they last long, but I think they only put out 1.2 volt, and the norm is 1.5 right?

No, 1.5 V is for batteries, rechargebles all have only 1.2 V.

15 minute to recharge?!! Wow, mine take 8 hours. :blink:

Ocatvious > Every rechargeable battery is 1.2v, 1.5v is for unrechargeable one.

I quess it's a quick-charger Octavious uses, my Energizers take some 8 hours too... Don't know if there are any drawbacks with quicker charging, like dimished life-expectancy for the battery...

 

[jonjandran]

These are the ones I use. The best I've found...

I use Uniross NiMH 2100 mAh batteries and they seem to last very long indeed. As a general rule of thumb the higher the mAh number the longer the batteries last. Also it depends on what clock speed you're running the GP32 at and if you have the light on or not. At a rough guess I'd say I get between 7 to 10 hours (mostly unlit) with two batteries.

Also as it's my first post here (Been lurking for about a month getting info and got my GP32 FLU for Xmas) I'd like to say hi to everyone here!

Don't worry, I'm not gonna start asking where to get TeH RoMZ for emulators

I got 6 1300 mah battries plus charger (6 hours) for 13 quid.

Aint used em for more than 3 hours yet though and that was only at 66mhz playing music.

 

[wildo2ne]

Got myself some 15 minute rayovac 2000mah batteries, they last anywhere from 7-10 hours in my 166 modded blu+, enough to keep me occupied while at work

an important note though is that you have to have the rayovac charger for them to charge in 15 minutes

its worth the price though, I have 6 batteries and takes me 45 minutes to charge them all from completely dead

btw spent about 30 bucks american for the charger and batteries

I got 4 2400 and 4 2300 mAh rechargables from ebay, for around £3. They seem to last for ages.

 

[Goity]

800 mahs, bout 5 hour with backlight at 133-180 mhz

​

I thought the highest that the Rayovac 15 min ones went to was 2000. That is what I have. Where did you get 2300mA ones from?

Ooops , you're right. They're 2000mA.

My crappy Energizers are 2300mA.

8 uniross 2300mah rechargables, I get 6 hours continuous with two batteries on DrMD at 166mhz with light and sound on. Good enough for me.

Ive always wondered why rechargeables are only 1.2V instead of 1.5V for normall batteries. This is fine for most things but in for example the hand controller unit for my petrol radio controlled car, that takes 8 AA batteries. So instead of being 12V its only 9.6V if you use rechargeable which im sure effects the range etc so I stick to normal batteries in it.

Infact on that note, can you generally overclock more if you use normal batteries due to the voltage difference or is it irrelevant as its all changed further down the line by resistors/regulators?

 

[Drumaster]

I want those.

The GamePark batteries.

I already saw them in 2 600 mah but can't find them again.

 

[Goity]

it's irrelevent for oiverclocking. things convert the voltage

3.2v Kodak 1700mAh RCRV3 lithium rechargables here. They're good for around 5 hours of 166MHz usage with the sound cranked, with a 3-hour recharge cycle. Had to strip the battery apart, tape some aluminum foil to the positive end contact, and remove the coils linking the two battery terminals to make it all work, though. (I can pop the coil back in at will so that AA cells will work, too.)

There's a guide for doing the Li-Ion mod here: http://gp32games.com/modules.php?name=Cont...showpage&pid=26

Now, if drilling through the battery compartment is off-putting, you might just be better off with Uniross AAs.

(Wonder if there'll be rechargable Li-Ion AA cells in the near future...they'll have to shrink the voltage-regulating microchip in the RCRV3 to fit in it first, though...)
