Battery zappers that truly make a difference are hand made by matching companies usually. These types will make a large difference in the performance of the cell. The ones for sale to the public(i.e. Integy) usually have little to no effect on the cell.

Nothing compares to the intitial zap... If it is done properly, it should never need to be done again... a maintinance zapper, can help only if the weld from the initial zap has been broken, or didnt work properly the first time...

A few years back i had a discussion at a hobby show with someone from a battery maker.. not matcher.. this is how he explained to me that zapping works...

inside of the battery is the chemicals, then on top is a plate, then a spring and then another plate.... as the cell charges this spring compresses and when fully compressed, the cell should be about peaked... now

what zapping does is weld the spring solid to the two plates.. creating a solid top rather then spring.. it allows the pack to peak faster, and that is supose to help bring up the voltage, and drop internal resistance... If the zapper worked well the first time this weld should not break.. if you zap a cell that is already welded, you can possibly damage it.. one you can cause the weld to break by a second zap, or you will see no change in performance... a maintinance zapper is not as powerfull. so it may help for a while, but not having enough juice the weld will break.. which is why it gives the apearance of working when you use it...

ive had packs re zapped and matched in the past.. ive seen no improvement in them... the rematching help, because you can place the better cells with the better cells,, but thats it...

There are no springs inside the batteries we use for the r/c application.

Jason, you are one crazy mofo, lol. Which cell did you take apart?

burbs - I don't know if it makes a diffence, but Sanyo only made up to 3000mah cells, which were not made specifically for r/c, the new GP and IB cells are made specifically for r/c purposes, not for medical tools or what not.

actually sanyo made up to 3600 mah cells.. They were not rc specific either.. They did not get the numbers as the GP's so they didnt cell as hot..



this is off the GP site.. It lists what there aplications are for.. also has a diagram of one of there batteries..Batteries manufacturers could not suport there business by only making rc specific batteries.. The batteries are still used in other aplications.. They just have someone in the rc industry helping them tweak cells to try to make them a bit bettter..
