Question about Bosch Home & Garden UniversalVac 18

Hello, just got the products. I assume it would be good one and as expected it comes in with no chargers and batteries. I thought it was compatible with one other product I buy from another shop but actually not. So I need to check out what is the charger or batteries that go with. Could you please let me know the charger model and batterie that I should buy from your website? If not available or too expensive I have to return it to you. The reommended accessories linked with the products might be an improvement you may make on the online shopping experience. Thanks
