New life

Our old battery is working like new again. My husband is glad to not have to buy a new radio for the boat.

Pleasant Experience

My CNB250 battery was rebuilt and returned just 4 days after I shipped it VIA USPS to MTO Battery. The craftsmanship is impeccable and I can hardly notice where they opened and resealed it. Thus far, performance has been wonderful and I have yet to run out of battery prior to charging.
