Absolutely disgracefull. Would never buy another battery from this company. Only had the battery for less than a year when it failed. Followed all their advice like recharging (many times) but when complaining, they wanted me to return the battery to them, at my cost.They said they would test it, but with no independant witness to verify their findings, they could have told me anything.so, in the meantime i would be without the car for probably a few weeks. I asked them for a replacement, or refund but got told to return the battery to them, at my cost. Was considering legal action against Tayna, but this would have meant many weeks of legal action and all the time i would not have been able to use my car. Decided that i would purchase a new battery from my local supplier, and if, which i doubt, i had problems, then at least i could get it sorted locally. I have now had to buy 2 battereis within a year. Would certainly not recommend buying a battery from this company as their customer service is abysmal.
