I must be getting old! It wasn’t that long a go a decent battery was $ 50. Now a decent battery is $ 100 and higher grade batteries are $ 150-$ 200 When the battery in my 1984K5 Blazer died and I didn’t want to spend a $ 100 on a new one a kind stranger directed me to Funderburks. I don’t know if the batteries are used or reconditioned but for $ 25(Cash Only) with exchange how can you go wrong. I was greeted with«May I help you, sir?» and when I paid«Thank-you sir I appreciate it» Took the battery home and installed it into my K5 Blazer and with a few pumps of the gas pedal, the beast roared to life. With the cost of a new battery, if I get a year or more out of this one, I have more than got my monies worth. If you need a new battery and can’t afford or don’t want to spend a $ 100 or more, then give Funderburks a try.
