Good company

It arrived quickly

It arrived quickly, although I haven't used it yet, the voltage is fine, I was able to charge it. I don't know exactly what secondhand means, but it looks new from the outside. I have previously bought 2pcs 24v/100Ah batteries from them and have been using them with satisfaction for my solar system for about a year. That's why I dared to buy a battery for my small boat here.

Great service

Son perfectos y de buena

Son perfectos y de buena calidad

Hyvä laatu

Hyvä laatu, palvelu ja viestintä, nopea toimitus
Kuten odotettua, tämä on tehokas akku asennettavaksi asuntovaunuun tai veneeseen.

Hyvän DC/AC-muuntimen kanssa se todellakin riittää sähkötyökalujen käyttöön kohtuullisen pitkään.

Sen käyttöikää ei ole mahdollista testata, mutta itse akku on helppo asentaa ja huippulaatuinen.

Odotan sen kestävän vähintään 10 vuotta.

Hyvä palvelu ja viestintä, nopea toimitus
