Excellent battery, the no spill and no maintenance does the trick. I am not sure if Gill has the same battery or not, but if they do Ill get it next time. Its too much money for a piece of led and plastic.

Our previous RG25 lasted nearly 5 years, which seems good for the Florida heat. This battery arrived charged [OCV 12.9] and cranked well. So far so good. Great service from Spruce also, it only took 4 days from order to delivery.

I needed a new Concorde RG-25 for my Alon A-2 Aircoupe. Aircraft Spruce managed to get one to me over the weekend with free shipping. I live in East Texas, and Spruce had the battery shipped from Dallas. Amazingly fast delivery and this, during the virus pandemic.
