Review

First of all, I would like to mention that, both flat top and button top batteries of same features are available. Know your device and be sure before ordering AKT batteries. These are superb in terms of quality, but people often order the wrong one mistakenly and leaves negative review.

ATK batteries are one of the most recommended batteries and compatible to flashlights of leading brands. Its capacity is proven to be 3400mAH as advertised. Besides, its high voltage makes it perfect to use in demanding applications. 

Its safety mechanism is a state of the art. It disconnects automatically in case of high voltage, high current, over charge or discharge and overheating. Batteries have 5 years of storage life and more than 500 charge cycles. Once you install this battery, you will not need another one for at least a couple of years.

FLAT TOP 18650 BATTERIES

2. V Force - IMR 18650 3000MAH batteries

Features:

  • Type: Flat Top;
  • Capacity: 3000MAH;
  • Voltage: 3.7V;
  • Packaging includes: Two - IMR 18650 3000mAH 35A rechargeable batteries.

Review

This pair of batteries from VFORCE come with impressive 3000mAH capacity to deliver tremendous power to the host device. Despite of the high capacity, it gets charged comparatively quicker than expected. It is available in a reasonable price too. 

The downside is, the manufacturer did not put any protective insulation in it for some obvious reasons. Due to the  lack of protective circuit, there is risk of overheating. But I did not get any complain about overheating so far. Some users have complained over the cover peeling off within a couple of months use. That is not a big issue, nor it will affect its performance. But this is somewhat disappointing for a rechargeable battery.

However, I will recommend this battery only in devices with built in protection circuit. Besides, it can only be used in 2.5 v devices. To power up expensive and more demanding gadgets, it will be wise to look for safer options.

Things We Liked

  • High capacity;
  • Holds charge for long time;
  • Long lasting. 

Things We Didn’t Like

  • No protective circuit;
  • Coating may peel off quickly.

Features

  • Type: Flat Top;
  • Capacity: 3400MAH;
  • Voltage: 3.7V;
  • Packaging includes: Six PCs -Panasonic 18650 3400mAH rechargeable batteries.

Review

You get six high quality batteries for the price of 4. This economic deal is somewhat risky due to China made dupes of these excellent Japanese batteries. So, be sure before buying. The China dupes shows 2914 mAh to 2990 mAh capacity in tester whereas the real batteries are 3400mAh capacity. 

These batteries are bare, free of any protective units. Hence, only can be used in devices and flashlights which has built-in protection system. This is the only drawback of these beauties. Besides, these comes right out of industry without any decent cover ups.

The brand name Panasonic represents authenticity and reliability. These items are no different; for reliable use for years for your flashlight or vapes, this unit can be a good choice.

Things We Liked

  • High quality;
  • Compatible to any device that runs on 18650;

  • Packaging includes: Two PCs -GMT INR18650-25R Flat Top Batteries and storage case.

Review

From the title you know, these are flat top batteries, hence, suitable for vaping. Its specs suffice the requirements you need to fire up your vapes. The matter I liked about this pair is, it comes in hard storage case. Personally I prefer purchasing tools which comes in cases for protection and storage purpose.

Besides, very few manufacturers mention in their advertisement about the lacking performance of their devices. According to the advertisement, these batteries form GMT are more likely to drop its capacity to 60% after 250 charge cycles. So, you will know what performance to expect when.

Like other lithium-ion 18650 batteries of this list this pair also comes without any protection unit. The budget friendly price may seem more appealing to some who does not need this pair for long term demanding applications.

Things We Liked

  • Suitable for vaping;
  • Mid range capacity;
  • Comes with storage case;
  • Budget friendly price. 

Things We Didn’t Like

  • Packaging includes: Two PCs -Imren INR 18650-High Drain Flat Top Batteries and storage case.

Review

The benefit of high drain batteries are, these are less likely overheat while charging and discharging and are suitable for demanding applications where high amperage is required.

These batteries from Imren are great to use in vapes and other high drain devices. These are available in an affordable price range. As these are high drain batteries, they charge faster. 

To fit this pair in an affordable range, quality is compromised a little. Its capacity will be reducing over each charge; will be half after 250 charge cycles. Its charge holding capacity will be reducing simultaneously. Some users complained about overheating when it ages, but overall this unit is just fine when this is new.

Things We Liked

  • Affordable;

  • Comes with plastic case.

Things We Didn’t Like

  • Performance degrades over time;

Review

Once you use this battery, you will never buy any other brand again for your vape mods. This flat top high drain batteries are sold in single piece, comes in a plastic container. It is less popular brand but the users are quite certain about its performance. 

The benefit of using a less popular brand is, you get pro quality performance in a less price. With these batteries from MXJOR, you will get every battery is authenticated separately with code. Hence, there is less risk of purchasing low quality product or replicas.

These batteries are solid, holds charge for impressively long time. Sufficient for your day long vaping. You get only one in the packaging; for non stop service you can purchase two, so that you never get out of battery when it needed most.

Review

Unlike conventional 18650 button top batteries, this pair from Panasonic comes with highly protected circuit. Hence, the size is different from the normal 18650 batteries. The diameter is 18.8 mm and length is 69 mm. A little 4 mm difference reduces the compatibility of this power houses to a great extend.

When I tested this battery, it exceeded all my expectations. It is advertised as 3400mAh capacity but delivers more than 3430mAh. Besides, its three layer protective circuits keeps the battery and the devices in use safe from overheating, over charging and over discharging.
