Step 1: Verify What the Problem Is
This Instructable assumes that you identify that the problem is the charger itself. In my case, a 15v power supply to charge 12v batteries was pumping out 3v. Get a simple multimeter and measure the voltage at the terminals of the charger. If the voltage is less than the rated voltage, then this Instructable might be for you!
Step 2: Find a Donor Power Supply
Since my 15v power supply is pumping out 3v, I need something else that has similar power ratings. The original: 15v, 200mA The new supply 15v, 800mA Well, the replacement is a bit overpowered, so there is a little danger here. If possible, find one that is a closer match than this one.
Step 3: Swap Power Supplies
I cut the wires to the original power supply, and tested the performance of using the new power supply before making it more permanent. It worked as it should - actually, much faster than it should. I need to be careful not to overcharge.
Step 4: Make the Wiring More Permanent
I soldered the wires to the original connection points and even made a pull-stop so pulling the cord wouldn't yank the wires out of the circuit board.
Step 6: Results
Oops, it looks like I need to test my batteries with the multimeter every time I charge for more than 5 minutes now, because the new charger is a bit overpowered... Once again finding a more closely matched power supply would have helped.
Step 7: Final Test
There you go, the light comes on and charging commences. It looks like this project is complete. Again, I put more details on my blog post , but the steps are the same.
Introduction
I bought the lead gel battery in an electronic shop for 10 euro or 12 dollar. The specs are: Nominal voltage: 12V, Rated capacity (10h rate): 1.2Ah, Size (L x W x H): 97 x 43 x 52mm, Total height: 58mm, Weight: 0.61kg (approx.).
Step 1 Repairing a Cordless Drill Battery
This battery operation concerns 12Volt, 14.4V and 16,8V cordless drills. First open the pack. Take out the battery cells. and disconnect the connector on the top.
Step 2
Next step is to take a 15cm long speaker cable. To one side you press 2 slide connectors. The other side you solder the top connector of the old battery pack. take care with the polarity. You can see the plus and the minus on top.
Step 3
When the cable is done we can push the top connector back. To hold this in place we have to make a spacer from wood.
Step 4
Now we have to find a way to connect the battery to the old box. The best condition is when the battery fits exact in the old battery box and that this can be closed. When not there is a possibility to use tie wraps to hold all in place. An other way is to saw the box open. On the last photo's you see how a Black and Decker is hacked.
Step 5
Last but not least the question; how to charge the lead gel battery? For a 12Volt drill you can use the usual charger. For drills with a higher voltage you have to use an adaptor with a 12V till 14 V unstabilized DC output. Its easy to connect the adaptor cable to the charger because there is no electronics build in.
How to boost dead battery?
Plug your AC adapter in and using the wires, boost your dead battery.
