One of our cusotmers did test for our Koyosonic 6V225AH deep cycle batteries in comparison with 6V225Ah batteries of some well-known brand. He is very surprised with the test result. Under the same test condition, our Koyosonic can last for 1H25M, however, T105 can only last for 46M. This customer imported from us 5 years ago and this is the first time for them to do such a test. And now they know why the users are very happy with our NPC batteries.

A piece of good comment from one of our old customers who has specially supplied military batteries to his country army. After the batteries were in service for more than 2 years, they wrote an email as below.

Dear Katherine, Thank you for email .Yes we took delivery of the batteries and deliver them to the Ministry of Defence .So far the feedback is good and the customer is pleased with the purchase. We will keep you informed of any news. Regds Dimitri
