18500 3.2V (3-pack)

These are serving their purpose in solar path lights. They are more powerful and much cheaper than the brand that I was purchasing before. Prior to buying these, I was paying this much for only two batteries.

Out of three batteries, one is faulty. It doesn't charge Hope other two runs for a while

These are the perfect replacement for several of my solar lights that the batteries have died in. They are perfect fit and worked right out of the package. As we had some sunnier days, they are fully charged, and the lights are nice and bright now. They are good value. They have been in our lights for about two months now and still work perfectly and the lights are still nice and bright.

The lights I bought three years ago have finally bit the proverbial DUST. I looked at them the other day and noticed the exact same type of batteries were in them as these. Luckily, I had not yet tossed them out. These work awesome in them and gave them a new lease on life! Bravo!FYI there is a number of times a battery can be discharged, then recharged before that battery starts to lose its capacity to hold energy. I don't want to get too in-the-weeds here but you can google it and see for yourself. Some of these battery types are Lithium Ion, Lithium Iron Phosphate, and the MUCH cheaper Ni-Cd (Nickle Cadmium batteries).The lights I replaced the old batteries in were $7.50 or so at a big box store so this makes reviving them a lot cheaper and why waste them by buying new ones when I can easily replace the batteries. Most consumers don't even know these store bought lights have replaceable batteries (some don't) but if you examine them closely you might be pleasantly surprised. On my lights the sliding, plastic doors the batteries reside in were fairly well hidden and blended into the body of the housing along the manufacturing seam. This is , I believe, deliberate. So you don't buy replacement batteries such as these but, instead, replace the entire housing.Yeah, pretty crappy, I agree.Give your old lights a look and see if they have replaceable batteries, you may save a few bucks and reduce waste a the same time. I highly recommend this route rather than sending them to the landfill.

When you build battery packs you needeach battery to have the correct voltage and the same voltage. These were all 3.36 Volts unloaded. That is a quality product.I am a cheap farmer so the price was great.Even LiFePO4 die after about ten years.I have a ten year old 60 Watt solar fence light. The battery pack finally died. They do not make that pack anymore so I get to build one.

These are good rechargeable solar batteries to replace old ones that have gotten very weak or don't work at all. I really like that they come in a 3-pack for my solar lighting needs. They perform as expected at a good price.

We have solar lights around our home. Having noticed a couple weren't working the batteries were replaced with these. They are now working bright and providing the outdoor look we enjoy.

A bit on the expensive side. The electrodes are all made of iron, which feels somewhat cheap. There aren't many options for 18500 batteries on the market, making this a decent alternative to three AAA batteries. However, it's only worth it if you plan to buy around 100 AAA batteries at this price. So, I wouldn't recommend it.
