Mini-guide - opening a Li-ion battery and rewiring it.

[MODDEDbyBACTERIA]

Nothing in any of my videos are ever fake. The batteries in the Li-ions are 3.7v each, 4.25v fully charged; AA alkaline cells if people want to recharge them can be recharged up to 1.7v each, however in reality they are likely to fizzle or leak after charging or weeks later so not good. Li-ions are designed for recharging.

thanks for the vid, i'm planning on making a 30 cell battery now which will also work as an airflow stand, but i took apart the battery on the vaio fz31z which was holding about 2 minutes, and found that all the cells show full life! i.e 4v instead of 3.7v on my cheap multimeter, what do you think might be wrong???

best regards,

Hard to tell from the description, but 4v indicates good charge (3.7v cells go up to 4.25v on full charge), assuming they are fairly recently charged (so amperage is strong), and charge not holding, may well be faulty cells that don't hold amperage like others do so the protection circuit is cutting off the power. Fully charge, check each cell, run until stops working, test each cell again; also if any cells are swelled they are dead and dangerous.

Where can you find the battery?

[MODDEDbyBACTERIA]

ebay. look for "Canon BP-915 battery"

I ordered my batteries(the ones you recommended to me) but I only ordered one. Is that enough for the n64?

[MODDEDbyBACTERIA]

One might run it for a short time, but not for long; you need 2 or 3 packs.

cool

[MODDEDbyBACTERIA]

Same principle, yes, however laptop batteries are slimline, so unless there were two cells vertically stacked, and your system could take the equivalent of double width the side of the cell (ie two side by side), may not be a lot of point. I relocated these Li-ion cells as it is far easier to position two individual cells than a pack of two together.

Thanks a bunch, but would this work for laptop batteries too?

[MODDEDbyBACTERIA]

I am pleased it helped. I tend to look all over the net on sites, blogs, forums and YouTube for research and general learning on general modding, and anything I can find on a console I am working on at that time, for any tips that help. Snippits of knowledge picked up from various places sometimes can be invaluable, I find!

Your protection circuit probably cut out because the terminals connected at some point, making a short; maybe something innocent like scissors, screwdriver on your desk?

THANK YOU BACTERIA!!! I thought my protection circuit was broken because my cells were working fine. I gave it a quick charge and it's working fine now. AWESOME!
