I have a courtyard villa and use them weekly - and the batteries need charging maybe every three times I use them. Good value.

Suggestion to all who own rechargeable tools. Read the instructions-most people don't including me. Lithium Ion they claim so many recharge cycles. You will get far longer life out of the battery if you do not run it till the tool stops working. Properly designed you cannot actually run the battery all the way down-the tool shuts off before that. The reason is that the battery is a pile of cells strapped together. One battery in the pile is always going to be weaker than the others. If, you run it all the way down the stronger cells will reverse the polarity of the weakest cell and you will not be likely to be able to recharge the battery pile.
Also, storing them and charging them in a hot garage increases stand by losses and decreases the life of the battery. The batteries often cost as much as the initial purchase with the tool the charger and two batteries.
