Bought these batteries for our exit signs. They work great and saved us a bunch of money, as the alternative is to buy new exit sign with lights. Very happy with the service from Battery Clerk.

Bought two of these batteries for out EXIT signs in retail store. I was unaware of battery backup until fire inspection. I was hesitant to purchase these because the price seemed too good to be true. But decided to take a chance. Batteries arrived and we popped them into the signs and they work perfectly ( so far for 2 weeks). Even the guy that services our fire extinguishers was amazed by the price and asked me for the website. I would gladly purchase these again.

We were very pleased with our order. The batteries worked great with all the exit signs we have at church. Saved us a lot of money in not having to replace the signs.
