Wilderness Systems Lithium Battery for Small Devices

So damn good I bought a second one for different uses. The first I bought for my fish finder. It lasts over 10 hours with continuous use.

i bought this battery as a backup because the first battery worked quite well. this battery dies as as soon as a load is placed on it. when i purchased the battery it said it had a 5 year warranty but now shows up on this site as 1 year. the company says contact Amazon and Amazon says contact the company. piece of crap company

Works great in a small package.

I don't believe I recieved a new product but rather a referb. The area where a part number typically goes was sanded off and a sticker put over it. I thought I would give it a try anyway. The unit lasted a few weeks before it wouldn't hold a charge anymore. I had to go through the manufacturer for warranty service and they sent out the same type of unit. This leads me to believe it's a manufacturer issue and not Amazon

This is the second battery that lasted less than a year. A week ago it worked great. Today it died in two hours and will not take a charge

If you're going to use this, buy 2.
