Just one more opinion about polarcell..

In the last years i think i bought more than 15 polarcell batteries.
Every battery respected the declared capacity and behaved very well even after hundreds charge/discarge cycles.

In the worst situation, the batteries that had the hardest life (high temperatures in my car, 2 charges a day or always in charge) becomed inflated after one year and some month.

As soon as i wrote to polarcell about the problem, they asked some photo of the defect and sent me a replacement battery IN WARRANTY - completely for free - that i received in 5 days.
In my opinion, for 16 euro, these are great products, with a great service support.
