Hacking EZflash 3-in-1 battery life?

[Searinox]

Does anyone know how long the battery of the EZ 3 in 1 lasts? As you all know the battery backs up SRAM saves, and losing your savegame on a game such as Pokemon can really really hurt after a considerable amount of time. Are there any estimates?

Do you mean how long does the save battery last until you have to charge your DS again, or how long it lasts until it's completely unusable?

Charging your DS has NOTHING to do with the SRAM battery in the EZFlash 3-in-1. I heard that the battery lasts about 2 years on average.

2 years?! Whoooooa waitaminute. I have my old pokemon red cart it's 10 years old by now, it backs up its savegames on SRAM battery just like an EZflash and it's still got my savegame. You're telling me that an EZflash 3 in 1, made with technology 10+ years more advanced, will only last a fifth of that time?!

Pretty much.

Think about it: you're putting far more pressure on the 3-in-1 than on your Pokemon cart, even if you are as big of a nerdy Pokemon fan as I am.

So backup your saves to your HDD or a flash drive from time to time. And replace the battery @ Radioshack or Walmart for a few dollars. And then move on

They should have included a flash chip, not SRAM for saving games. I mean at 32MB permanent memory chip what would have been the cost to throw in another 512KB chip for saves too?

Anyways I replaced the internal CR1220 battery of the cart with a CR1620. It's got double capacity, so I'm hoping it'll last me twice of... whatever it was designed to last. I still can't find clear info on wether it's 2 years or 3-4 like cory said he calculated on the EZV forums.

You are probably talking about the RTC feature of your original GBA pokemon game. This game has a flash memory and a battery to maintain clock time (RTC).
So, it's not a surprise that flash memory keep better data (here, GBA save) than SRAM one.

And concerning battery life of the ez 3in1, got mine since march 2007 and i can always read 3v on my multimeter where it should be 3v, so ...

i have some questions

1 is the battery being consumed when playing nds games and the ez flash is attached?
2 does it save battery life by removing the ez flash when not in use?

i have some questions

1 is the battery being consumed when playing nds games and the ez flash is attached? It is always in continuous use.
2 does it save battery life by removing the ez flash when not in use? No

The battery powers your save file that is stored in the SRAM, where you play or not.


Don't necro old posts, it is bad manners unless your the OP in most cases.

 

[zeroel]

thanks and sorry about that didn't mean to just thought my questions are related thats all. No harm intended.

You must be a magician if you replaced your CR1220 with a CR1620. I'm bumping this thread because the EZFlash 3in1 is still widely considered the best SLOT-2 flashcart solution, but it is shipped with a shitty battery. So, when my battery decided it wanted to be a douche I googled around. After reading this thread I decided to order a couple CR1620 batteries, guess what. THEY DON'T FIT.

It isn't snug, they just DON'T. FIT. I tried EVERYTHING believe me, I'm not an idiot. I cut off bits of the plastic, doesn't work bro. You must be merlin, or you just pre-emptively said you did it.

The only conceivable way it could work is if you cut the top of the plastic of the cart and made a hole that the battery would stick out of, leaving it looking ugly and exposing the electronics inside for dust damage.

Don't use a CR1620, just buy a couple CR1220 and if it craps out then oh well, your saves aren't destroyed because they're saved in the GBA_SAVE folder.

Hum... no.

Pokémon Red.
There's no RTC in that.
And it uses SRAM.
