I was recommended these batteries from a friend of mine, so I thought I’d try them for my e-cig and see if they were as good as he claimed them to be. I bought them and received them fairly quick — like within a couple days. Upon using them, I can say these were some of the best batteries I’ve ever bought. The battery life on these surprised me and convinced me that you don’t always have to spend a lot of money to get good quality products. Would definitely recommend to anyone considering buying IMR batteries, Ecogear knows what they’re doing!

This company is reliable and never fails to be attentive to customer service needs. The batteries are of great quality and offer far more than your average vaping battery typically would. What I love most is how quickly I received them in the mail after ordering them! I ordered these thinking that I was receiving something moderate and nothing of higher tier quality. I sure was wrong. In fact these batteries offer a longer battery life, strong durability and better overall than some of the others on the market. I totally recommend these batteries for anyone who wants a longer hold battery life for their vaping pens.

The 18650 IMR battery 2-pack is one of the best purchases I’ve made and I trust IMR batteries in a lot of my vaping products. The batteries were received in 3 days and honestly, I couldn’t have been happier. These batteries are some of the best I’ve ever used with my vape mod. The quality and charging is great, these are a battery you can’t pass up for vaping. If you’re searching for a battery that offers quality and adequate amounts of usage per charge, well then, these batteries are for you.

Battery life was good but wasn’t spectacular upon arrival, although it does perform well. Upon testing the batteries initial life, when I received them, showed to have only a 20% life. This is my first time buying a battery replacement so maybe they are shipped with a partial charge. When I fully charged the batteries, I saw an enormous difference in battery life but I still feel they should be shipped with a full charge.

Bought three of the IMR 2-packs and one battery inside of the 2 packs failed. It was not doing anything, not powering my device, not charging on my charger…nothing. I hope no other customers had this problem but I was disappointed to see the defect in the one pack, even though the other two worked perfectly. I contacted Ecogear for a product replacement and the new batteries are working great.

The batteries are packaged with a good and durable wrap. I use these batteries for my vape mods and the battery life is good but It could use a little more juice in my opinion. I would recommend to use these batteries for small vape box mods or pens. Overall great batteries for their value and offer a moderate amount of power for their charges hold.

The main reasons I buy my IMR vape batteries from ecogearfx are due in part that the reviews for them are good and they are reliable. On the downside, the shipping bothered me. My batteries weren’t shipped until about 2 days after I paid for them. Maybe this was due to the holidays. For most purchases, I wouldn’t be so bothered about this but I was in a rush for a replacement batch. In the end though, I’m happy with my purchase.

I have used different kinds of IMR 18650s and these are definitely the ones I go to for high wattage. They’re shown to be safe and also consistent from batch to batch which, in my opinion, is of great importance to me. If you’re familiarizing yourself with high wattage batteries then this should be your first go to IMR battery. I will personally buy several more boxes to keep for extras.

A decent battery and good quality. The charge hold it is far worth the amount you pay for it compared to more expensive competitors. Aside from the cost, I would say the IMR 18650 at the top 5 list for batteries to consider. I noticed that the previous battery I used lasted slightly longer but it is almost of no significance due to peek power being higher output. The IMR 18650, for its cost, is a better value than other batteries I have used.

The IMR batteries I purchased have always been great and that’s why I continue to buy these 18650 batteries from Ecogear. I was able to get a couple of 2 packs of 18650 batteries for about $26 with free shipping, that’s a good price. The charge on each battery lasts a long time and if its only being used moderately to lower amounts for usage, it could last you for weeks without a charge too! I received the batteries 2 days after ordering and I’m very satisfied with this purchase.

Fantastic!

I think I bought this batteries about one and a half – two years ago. Now I’m buying again and just to let you know, I can put these against any name brand batteries and it will perform close to it or even better.
