Unfortunately, the batteries of Bulle break for no reason, I must say that the cells of the battery are of pure second-rate Chinese manufacturing. Conclusion: the tools are great, but not the batteries. The best batteries are made by Makita and Metabo.

In all battery-powered tools, you should know that batteries die after a certain number of charge-discharge cycles. Lithium batteries are not eternal and should not be left in the hot sun or in extreme cold (-10) as they will deteriorate. This specific tool is quite good for every use.

After two years of very mild and occasional use, the batteries broke (both of them) as if they had an expiration date.
