Ni Cad battery fix ??

I know there are a few clever electrical folk on here
I see a few ads like this on ebay . Does anyone know if it works or is it just a scam .
EZ BATTERY FIX 4 Makita 9.6 12 14.4 18 24 volt v 18v Item number: 200199656944

I have quite a few 12 v makita batteries and they are all getting to the age where they are failing , so if it works could save me hundreds

All the info you need is on the net. usually you find it's just 1 or 2 cells have gone - it's easier to test them and make say 2 good packs out of 3.

I have made a great mod to my 12V drill after all the batteries died - i fixed a lead with a cig lighter plug on the end. Now I can plug it into the car or a battery booster pack and the drill is far lighter!!!

Talking of drills why do they insist on selling them by voltage? The amperage of the battery is far more important. Give me a 12v 100amp than a 24v 2 amp any day!!!

I did think that too but if it is a scammer then i object to helping their cause . i paid a similar fee for phone unlock info and just recieved a link to web site with a crappy download thing that has stuck on my computer for ever and never worked .


Thanks Codders Ill take a look . having heard stories of charging Ni cad wrong and blowing it up so zapping them with a car battery is a bit scary

I can see where you're coming from. Don't blame you.
His feedback isn't bad though.

I have just had qty. 4 13.2 volt ones rebuilt. Not cheap but lower than buying new. $150.00 for 4 bat. packs. Yes, the cooler they are the more charge they accept particularly if they are aged. Just a tip: always discharge ni-cads before recharge to overcome the memory problem, however, never run them dead flat as when you recharge your run the risk of one or more cells recharging in reverse polarity; now your bat. pack is foooked.
Spent 13 years working for Chloride/ Exide so been there.
