Did this video help you?

Spooner Baumann: An explosion would have made for a much more interesting video

MrMac5150: stick those leads in your ass

ElectroAfrican: Nice work. Are you aware that your lighting gives your eyes a very eerie appearance, just saying, bro.

aussadroid: But how do you tell the negative and positive terminals? 

Robin Adams: Thanks, Spooner...I like home fixes. I have old battery packs still in good condition. They will only partially charge. (individual 'bricks' :: < like this, of 4 (1.2V) NiMH >>or 4.8V total/per brick. I want to fly my 'million dollar' ;) Harbor Freight Yellow Bee. I have a variable charger that came w/my Blade 350QX. Is 'CPR' (jump volting) even an option/safe option for my situation? I don't want to drive 25 miles for a battery pack. Thanks...Spooner or anyone interested. 

Lee Wee Ken: Fantastic, Good sharing on Jump Start.Happen when you left the battery without charging for a long time.

Mike Lonergan: On ac adapter does it matter which wire(solid black or black with white stripe) when connecting to positive and negative on battery?

rfn944: If you worked with batteries before you should know polarity is important, yet you never mentioned it. Could cause charger and batteries to burn up or explode if you get it wrong.

Stellar148: Thank you for spending time to share your knowledge. God bless you. Let the good you release into the world be returned to you 1000 times

aminuk23: you forgot 2 things, 1st voltage is not what it counts to jump start it's the amp, 2nd to keep battery for long you don't drain it completely but you reserve some otherwise you have to jump start to recharge again after non long use.

Skunkpu: You have black eyes like Satan. Not sure I like that. I'm intrigued but wary. Regardless, good vid. Thanks for the help. My battery now works. Hoping I can still get into heaven; though I may have received help from the devil. Peace.

earth: Darn, three months. Did you drown?

guily6669: Yeah, F**** it. Hate batteries so badly. My Duracell 8 AA cost almost 40€ and had only a few cycles, but I stopped flying, so they just stay for 4 years, and don't charge anymore. Imax B6 says it charges only like 34 mah god damn it. But i Put the 8 all together, and don't know why, but the charger is charging at around 20V and I was using 1A.

Kai Chinn: good job, glad you got it workin bud! ;) A lot of people do not know about the "Jump-Start" theory and glad you posted this for everyone! ;)

sailingsolar: So what happened? Did you do it yet?

Ansul Joshi: dude i have a 12.6v battery and it was broken [the solders came out] so i soldered it again and then i took a ac to dc adapter which converted the current to 9v and i am not able to charge it so can you help me with that

Blackbird8023: Not a bad video at all. Might i suggest instead of doing such an elaborate set up use a decent size capacitor to condition your battery.

Josh Nuno: like the guys from the x-files movie

sailingsolar: Did you not pay attention to polarity or not? Does that matter?

emerald640: A friend who is an engineer used a homemade charger similar to this and left the charger on overnight. The next morning the batteries had blown up and blew one of the batteries through the wall. These batteries have a high internal pressure and if you leave an unregulated charger on them you may raise the temperature enough for them to blow apart.

YouStubid: I have tried zapping NiCd batteries but even if I got them to charge and voltage went up they didn't hold charge for long and started discharging rapidly. So I'd say this trick doesn't make them very usable and it's time for new battery, sadly...

Pomi Jan: @Sam and Dean, there's a demon in the house

Deja xoxoscruff: Your eyes look scary

Lapidj0: HE SAID IT WILL BE BACK TO LIFE HE SIAD Why in the hell you didn't tell me it Explodes!!?? LI-ION

Ahmed Adly: I have issues with nimh battery packs for under water scooters. They cost $700 each and I will try this on them :) I will post the results.

wombatthing: WOOT! TEAM LOSI! Also this works great! Helped me fix my roomba

Richard Porter: NEVER try this for any Lithium based battery, that includes Li-po and Li-ion!!! You will burn yourself or you house to the ground. It Will bust in to flames and EXPLODE!!! Good tip for NiCad and NiMH, Thanks!

Detroitblue: Black Pupils EEK!

4thGloryMonday: right on man

wasfi hfaidhia: looooooooooooool sorry !!

watlingfen: BE VERY CAREFUL overcharged or boosted nicads can explode . UK, Eire, Australia and New Zealand with 230/240v AC mains supply please remember USA/Canada has 117/120v AC Mains.

joe joe Mama: lil tip.you could of yoused a 9v battery clip and reverst it insted of the clips and wirer

Ufuk KILIÇ: Does this solution work for Li-ion batter too?

tinoushgtr: for micro t you can use a peper clip to jumpstart the battery. just plug the battery then connact the red wire using a paper clip to the + side of battery case very short. light wil come on. a paper clip is too short to reach the both sides so just use a wire fasten to the clip.

liquidspherez1: Thank you!!!!!! Great teaching;-) Very helpful.
