Excellent customer service!! Very helpful and thorough. We bought 2 batteries here for our RV back in April, and have been having trouble getting a full charge this summer because of the lack of sun for our solar panels. I stopped in today to get some advice. The two gentleman that were working today spent over half an hour with me; tested the batteries, checked the hookups, explained about battery charging, and were very determined to help me solve my problem. They offered to charge the batteries for me, but I decided to purchase a charger so I know they are always getting a full charge. I highly recommend this location!

Great people work here! Go above and beyond to get you the right battery!

Had everything I was looking for

Always helpful and knowledgeable. Fantastic service! Best batteries around!

This is a shout-out to Scott from the Merrimack NH Interstate All Battery Center who went above and beyond to help me out while I was swapping my battery in my sedan. I was expecting a simple swap, but I accidentally dropped a piece of the battery terminal clamp down into the engine bay (weve all been there). I spent probably 30 minutes looking around for it, and Scott spent about 15 right along with me. Thankfully the part was eventually found. The battery is working great, and I will be back next time I need an automotive battery. Thanks again for your help, Scott!

Great service and prices. Love that they do watch battery replacement! Friendly and helpful staff. Convenient location. Nice clean, well lit, well stocked store.

These people are the best! Excellent products. Purchase all batteries here. They even replace batteries, key remotes, watches. Very helpful and knowledgeable. Have maintainers to keep batteries charged in off season. They know and stock a huge array of batteries. Highly recommend!!!

Bought a couple of batteries for a truck Im working on. Great customer service and friendly staff members helped me out right away. They have a great assortment of battery accessories and jump packs, flashlights, and hard to find batteries.

They have just about everything you need

Great place to get my batteries for almost any device. Great customer service and awesome people. Worked with a young lad named Jared and he was fantastic!!

Five stars for customer service! I will return for any/all of my battery needs. The gentleman who helped me was very nice and considered my best interests instead of his own when suggesting a solution.

Very helpful.

Great customer service.. Everyone is always eager to help. Best battery shop in town!!!

These guys are good, abs their batteries are top rate

Great service

John at the counter is great guy to deal with along with everyone else. Good prices also

I have gotten a few batteries here in the past. I mainly buy the refurbished ones as they tend to be cheaper. Noticed they do charge more than the interstate battery dealership in Tyngsborough. Their flashlights are pricey but good when the buttons work but when they break you are out of luck.

Great service every time, thank you Jon!

I purchased a dog collar battery and met John Cyr. He was Extremely helpful. Offered to test my old battery and confirmed what I was purchasing was the correct item. We began to discuss flashlights and he took the time to explain the differences between Watts, Lumens and lux. I will purchase all my batteries here in the future. Historically I find Interstate car batteries unsurpassed.

The person behind the counter was rather rude. I needed the battery, otherwise I would have left. I won’t go back. Edit- I needed a new battery for my 4RUNNER, I didn’t go to Interstate.

My go to place for ALL my battery needs. John is very helpful and has the odd batteries no one else has.

Great service and the best batteries

Total crooks- took my battery in after it failed, and they said they have the right to jack up the price of a new battery so there waranty is fubar!! You end up paying full price!! What a joke!!

TRUCK DRIVERS Be sure you have a hammer when delivery batterys.

Fast, professional service!

Quick visit

Excellent service

Batterys I have say 30-month warranty right on them. Its 11/21 bought new 2/20 well within the warranty period. And they refused to warranty the batterys. That will be the last time I use interstate batterys
