Don't toss battery powered tools when power pac dies
If you haven't noticed replacing a dead or weak power tool battery can ofter cost about the same as buying a new tool with battery. When this happens I solder some 18ga extension/lamp cord to the tools battery contacts. A 5AH 12v AGM battery can be had for less than $20 even at the lower voltage the battery supplies enough amps to almost equal a 18 volt tool battery. If you put 2 of these batteries in series they will be the most powerful 24 volts you have used. Recall 12 volt AGM are just lead/acid batteries with a glass mat between the battery plates so fully charged the output is 12.6 volts. I install battery clips on the 18ga extension cord and have the batteries in a small basket. I agree it's not as light as the self contained battery but you can still use the tool far away from any AC outlet and the battery pack will work with all your battery powered tools tools.
If the tools is variable speed never use more voltage than the original power pak because it may destroy the trigger speed control, less will work fine.
Say No to replacing disposal battery powered tools while saving $$.

Or you can just buy another tool that uses the same batteries and get 2 new batteries and another charger with it.
