Most Helpful Customer Reviews
   Ducati Battery
By on Sep 28, 2011, Ownership: Use regularly, Knowledge Level: Electricity doesn't scare me.. usually
(88 of 170 customers found this review helpful)

Pros: This battery fit fine for my 2005 Ducati Monster 620, the price was excellent and shipping was fast and free.

Cons: There was a damp spot (about a dime size) on the cardboard surrounding the battery. I put thin bubble wrap under it in the bike. I'll check it in a week and see whats going on.

Other Thoughts: We'll see. If it's leaking, I'd like to see good customer service.

**Note from BatteryStuff**
Small damp spots are considered normal, and occur during shipping because of atmospheric pressure changes. See article for more info.

(83 of 159 customers found this review helpful)

Pros: No shipping fees Fast delivery

Cons: Battery didn't work and didn't honor their product. I installed the battery exactly as described in the directions and my motorcycle's technical manual. The bike started fine and ran for two 2-hours trips. I parked the bike for one week and when I tried to start it, the battery was dead and will not charge. When I called, they said I must have done something to the battery and that whatever I did wasn't covered under the warranty.

Other Thoughts: Next time, I'll purchase my battery from a local supplier that has always stood by the products they sell. **NOTE from BatteryStuff: Battery experienced a short circuit, provided by the voltage readings given by customer. This can only be caused when the terminals are bridged, not a manufacture defect, therefore not covered by warranty. A replacement battery was offered at a great price, but customer refused.**

Pros: I have been running these batteries in my Top Fuel Harley for 7 years now with out one failure. The vibration is usually what takes out the batteries we run so if your looking for one that can take a beating and keep working, Highly recommended.

Cons: Haven't found one yet!

(1 of 1 customers found this review helpful)

Pros: 1st time around I choose a cheap battery to save cash. It worked badly, not holding a charge, etc. BatteryStuff coached me through testing the battery and the bike. Battery tested poorly but within specs but BatteryStuff exchanged it at no charge anyway. The 2nd had the same problem and wouldn't work in my bike. I asked them to credit it towards a better (& more expensive) unit but they sent me the MX/Yuasa at no charge. They even paid delivery.

Cons: Only had it for about 6 weeks but so far it's doing it's job perfectly.

Other Thoughts: My lesson: Don't cheat yourself by buying a cheap battery. Spend the money to buy the best one available and buy it from
