Was pleasantly surprised getting the battery replaced for free, as bought it here nearly 3yrs ago and luckily enough it was still under warranty (as shown on the original receipt that I kept).
Thought it might of been a hassle or maybe some hidden clause in getting it replaced, but they just checked/tested the old one - that was showing up as faulty and at the end of its life, and dropped in a new one. 3mins job, done.
Didn't try to sell or cost for anything else, which is a pleasant surprise when using a garage/mechanic type service. read more
