    • Perfect for our moped
Perfect for our Moped. Was fully charged. Easy to install. No leakage and fit perfectly. Works perfect and no issues with battery life.

This is my second one. The first one was subjected to abuse from being completely drained and left with the key on for several months. The battery had been recharged several times and bounced back. There is only so much abuse a battery can take and after the third or fourth full drain, it gave up. A true warrior. ... show more

    • Perfect TTR50 Battery
Was charged and fits perfectly. I have no issues with the battery holding a charge. Standard battery care seems to work perfectly to keep this one in use. Great price and great product.

Review Image by Paying Customer Paying Customer
Many things. I've used these on their side before and I've noticed small leakage. Be careful what you buy it for because it's only good for small electronics, etc. I've bought about 4 of these now. Last time was the one the had the small leakage and after just two days running only a small USB powered device it lost charge. I tried to charge it and it is now at 0.01v and will not accept a charge. Strange that they can ship you batteries but you cannot ship them back. Knowing in a SLA battery (S stands for SEALED) and it still leaks it obviously has a defect. I had to send photos. I know the response will be that it looks OK. Just be careful what you're planning to use it for since it's only 2.3ah and know that the success rate for me has been 3 out of 4 and in the 1st and only, and now final failure, it can't be returned, even if defective. ... show more

Worked well to revive a TTR50 I had sitting in the garage. Inexpensive and functioned well without a wake-up charge. I was able to charge it using a 2amp charger setting. Hard to attach jumper cables to the small battery plugs. Used a smaller alligator clamps to make it work. Had to charge as my wake up efforts and carb tuning required a good amount of cranking. This worked great. ... show more
