The way you recharge your battery impacts the life of the battery.

How frequently should I recharge my 21700? We specifically recommend 21700's because they have the ability to be recharged 300 to as many as 2000 times. You want to select rechargeable batteries that can be recharged many times. They can only be recharged a limited number of times. This happens to any rechargeable battery such as an 18650, 21700, 26650, 14500, AA, AAA or even a car battery. As the battery is reused (recharged), the battery degrades due to oxidation and electro-chemical degradation. The trick is that the bucket also gets filled with other junk over time, so there is less room. How many times can you recharge an 21700 or other battery? But 74 21700 are smaller than three car batteries. In comparison you would need three 12v 40 amp car batteries. So it would take more than 74 of these 21700 batteries to run the air conditioner for 1 hour. A small air conditioning unit that can cool about 9000 BTU uses about 1100 watts per hour. How much power does an 21700 have?Ī 3.7v a 5100mAh 21700 stores about 3 aH to max of 5 aH.

See “ Battery Recycling – How to Recycle Different Battery Types and Corroded Batteries Safely”. If a battery is damaged or looks corroded or appears to be leaking, get rid of it at a battery recycling center. The protected batteries normally have a “button top”, but check the specs to make sure. Unprotected batteries should only be used where the load/draw and charging is externally monitored and controlled. Unprotected 21700 batteries are cheaper, but we do not recommend their use. A 21700 protected battery is safer than an 21700 unprotected battery (less likely to overheat, burst or start on fire). The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. Protected vs Unprotected 21700 Batteries?Ģ1700 protected batteries have an electronic circuit.

Protected Mode: is optional but we recommend ONLY protected mode 21700 batteries.

LiPo – we are not aware of any lithium-poly 21700 batteries.

Max Continuous Discharge: Varies by battery.

Amperage (mAh): varies by battery – 3000mAh to 5100mAh.

Charge time can vary with amperage and voltage of the charger and the battery type. The average 21700 battery charge time is about 4 hours. Unprotected 21700s typically have a flat top. Protected 21700 batteries generally have a button top. We absolutely recommend protected 21700 batteries. There are two types protected and unprotected. The 21700 is physically larger than an 18650 battery, and AA/AAA batteries.Ģ170s may have a voltage range between 2.5 volts and 4.2 volts, or a charging voltage of 4.2 volts, but the nominal voltage of a standard 21700 is 3.7 volts, just like the 18650s batteries. The 21700 cell has voltage of 3.7v and has between 3000 mAh and 5100 mAh (mili-amp-hours).

How can I measure the quality of an 21700 if I am unsure of the age of a battery?Ī 21700 battery is a high capacity lithium ion rechargeable battery.

How frequently should I recharge my 21700?.

How many times can you recharge an 21700 or other battery?.

Protected vs Unprotected 21700 Batteries?.

Like almost everything at OOD, Pricing is very competitive even after shipping costs and the shipping itself was smooth and swift. TLDR my review mirrors that of Captain Xaviers and justajolt’s youtube review of these.Ĭharging these usually take less than 10 minutes with the Coolook IMR charger usually less than 5 minutes was enough for me. The worker Hurricane and other blasters wired for 14500 IMR-style batteries should work flawlessly with these batteries.

However as expected the stock blaster’s flywheels did shut off if revved for too long and shut off especially quick in my rapidstrike (which is full auto) when fired, except for my worker Hurricane. They bump rate of fire and FPS by about 5-30% with 2 of these and 10-40% with 3 of these in a stock 6V blaster. Sizing of these is pretty much identical to off-the-shelf standard AAs. These work great in my worker hurricane and all of my stock DZ / Nerf blasters.

And do not mix these with standard AAs (alkaline or NiMH) or any other chemistry aside from dummy batteries and LiFePo4 batteries in the same blaster. Do not use on stock blasters that you can’t run the risk of breaking These batteries are safe for YOU, but isn’t guaranteed safe for the longevity of your blaster. Fully charged they are around 4.2V/each, as I have found out from OOD. Shipping price is also pretty competitiveīefore the rest of this review I wanna disclose this first: these batteries are 3.2 volts / each PRE-charged. Shipping was smooth and fast as per usual OOD packaging was good and it comes in the plastic packaging seen in youtube videos.
