Default Integy Battery Xapper 3300DX

Any guys use this item with success and what settings do you use if so? I know this will mostly be a thread of opinions of what works for so-and-so... so noone is held liable to being a battery scientist for the answer they give here.

I have the previous version 3000.....analog display. It is a maintenance zapper. I use as high as 70 volts to wake up "tired" cells and to "top" off before the mains......i have seen some improvements on old cells but they "fade" after awhile.

Jeep: Thanks for the reply! Im assuming the 70 volt setting is something you use on cool cells? Discharged? After cycling? I havent gotten into battery maintenance since RC2000 cells were the hot ticket. I just basically charge and run them with little, if any other maintenance. I just want to be sure i dont damage the cells i have. Thanks for any help!

I just picked up one of those zappers! Ever since my learning experience: http://rctech.net/forum/showthread.p...threadid=37107

I've zapped a bunch more cells no problem. The NiMH have REALLY improved, Voltage has gone up and AIR has gone waaay down according to my GFX. My Nicads though are odd. Voltage seems to have went DOWN and AIR has gone up I haven't cycled them yet, so that may be why.

Oh, I zapped all my cells after they were put on a tray and dead shorted for a couple of days. I used the two voltages that gearless recommended and the adice that everybody else gave me and it's been great so far.

Good info Gutter! Thanks for the reply. I do have a few questions. I was of the impression dead shorting the GP's was a bad thing? I have heard alot of talk about it, but never tried it on NIMH. Are you using a GFX to bring down the cells to .90 individually? Or a tray after you disassembled them? If i am repeating questions, dont mind me, i was up all night building another computer.

Hi DaveW,

I have not yet enough experience with dead shorting so I can't answer you, but some matchers swear by it, and others tell to dead don't do it !! So,...

Regarding how to prepare the packs to zap, here's how I do it:

1. discharge to 0,9/cell at 30A on my GFX
2. put them on a tray (rayspeed, eagle, or similar) equalizing to 0,9/cell
3. then bring them near 0V on tray
4. zap with 70V on new cells, or 50V on older cells
5. let them rest (more or less 72h)
6. cycle to see how they perform
7. if not performing better I repeat the process with 70V
8. if they stay the same, buy new packs

I never disassembled my packs.

Be careful, and good luck.
