Complete Battery Source in
Okemos (MI)

Nick was absolutely fantastic! The knowledge he has regarding automotive batteries is far superior to the four other stores I went to. Do not waste your time going anywhere else(not trying to sound "sales-e)." GO HERE!!!

Very good service and help with our mobility scooter

Nick helped me out a ton. My car died at the meridian mall and I called about 10 minutes before close. He said he’d wait for me and stayed open late. After i bought the battery, he was nice enough to offer me a ride so I didn’t have to walk a whole mile with a car battery. He totally went out of his way to help me get home.

The customer service was excellent! I got exactly what I needed at a great price.

Super helpful, they were able to recycle my old lithium batteries without any hassle.

They charge three dollars a pound to recycle and bad attitude.

Nick was very helpful. He took his time working with me to find a solution to issues I had with a battery. Thank you !

Very knowledgeable and helpful! Will be returning with other battery questions!

Great place for batteries and replacement. Staff is friendly & helpful, with great inventory and quick service.

I've been in a few times recently to replace a sump pump battery & have a power tool battery pack rebuild, at Nick's suggestion. Nick has provided excellent customer service each time I've been in, and he really seems to know his stuff! I will make this my go-to battery store!

Purchased a battery for lawn mower and a rechargeable flashlight. The gentleman that assisted me was very helpful and efficient. Reasonable prices also!

Nick was knowledgeable, friendly, professional, and quite helpful. He answered all of my questions without causing me to feel like an idiot for asking. In addition, he has great taste in music. As well as the best vinyl collection I've seen in years. This location is the ultimate go-to for me.

Nick was excellent. His desire to be helpful and serve the customer was refreshing. I have no regrets spending a great deal of money for golf cart batteries here.

Very helpful and knowledgeable. Ordered batteries for our lawn mower that we couldn’t find anywhere else, then helped with replacement and recycling the old batteries. Running like new again! Thank you!

Nick was friendly and knowledgable, and replaced my watch battery quickly. You don't find this kind of customer service any more. 5/5 Would recommend

Nick was great. Super knowledgeable. Didn't have the exact battery we needed, but got us one that worked for a lower cost.

They didn't have what I needed, but it wasn't their fault and they were super friendly and willing to help me out!

great, knowledgeable service, they know their stuff about batteries!

This place has everything you need. Great customer service! I have been a customer for over 10yrs.

Tried to buy battery today, but had to leave as the worker had no mask (wearing a Trump hat if course). Took my business to the shop in East Lansing where they bother to protect public health during a pandemic.

Provided my wife with the wrong product. Won't accept returns without receipt, even for store credit. Refuses to admit own mistakes. Rude behavior. Poor customer service. Doesn't wear a mask. It was more about the rude behavior, inappropriate language to my wife, and disregard for my safety by not wearing a mask than the 14 dollars.

Complete battery source is the best place for my battery needs. They have good priced aaa and aa batteries for all the kids gadgets, and they are very knowledgeable about all my other battery needs (example... Which battery to get for my popup camper, and how to take care of it). Keep it up!

Helpful staff. Needed a marine/RV deep cycle battery for a sump pump. They checked the old battery and drilled a hole in the cap off the new one for the water sensor

These guys are the battery geeks everyone needs from time to time. They pride themselves in finding any battery you need. Prices are hard to beat as well. Highly recommend these guys if you are having trouble finding a battery OR if you are looking for a much better battery pricing.

The man I spoke with at Complete Battery Source was extremely helpful and installed my battery as well. I was in and out with a new battery installed in probably under 10 minutes. I would definitely recommend this store.

Complete Battery Source is THE place for whatever kind of battery you need! Not only did they have all the special batteries I needed but the young man installed all of them in our devices. I was impressed with the knowledge, professionalism, and courtesy of the staff. I highly recommend this store!

Honestly, I ordered this product on July 25 and received the battery for my scooter on August 15th. Do the math, I waited 19 days for it to arrive!! Thankfully I had another ride. Very disappointed in delivery time, with no excuses provided. I think its the "middle man" syndrome. Best of luck all. Jeff in San Francisco...........
