If the batteries
in your cordless power tools just aren't what they were try putting
them in the fridge before charging them.
If you have two batteries to charge, put them both in the fridge for an
hour or
two. Then charge one battery, when it says it is charged, swap it for
the one still
in the fridge. By keeping the batteries cold you can trick the charger
into
thinking the batteries are flat and the output will be considerably
higher. Repeat
until they just can't take anymore charge.
You will notice a big difference in the battery's performance.
