Chop saw bosch 18 v

[Piechur]

Hi. I have problem with chop saw. Its working only with 2 ah battery, if I use 5ah or 12 ah the saw started but wery slowly and after few seconds stopping. What you think the electronic its broken? I uploaded moves on YouTube

I assume that the 5ah and 12ah batteries are fully charged and work correctly on other Bosch tools?

Suggest you contact your local Bosch service agent for advice.

working only with 2 ah battery

Sort of points to the other two being knackered.

Yes the battery 5 ah and 12 ah is full charged and wery good condition. Sometimes when I use 2 ah and after few minutes use 5 ah everything working good. I checked the solder connections looks great same like wires. I don't know how check electronic module.
