The capacity of these batteries lir20322 on average around mAh CR mAhbut they can handle discharge rate of about 70 mA, while CR max burst discharge rate is mAh. The main change needed was the value of R3, which is responsible for setting the max charge current. Learn how your comment data is dataeheet.

You can test it easily by checking the other charge rates. My question is can I use this charger to recharge or do I have to add a resistor to the Negative side before I can safely charge the coin battery?

IEC standard defines battery as a round cell Maxell CR lithium batteries -pack of If so, is there a Lookup List of some lir20032

Many thanks for and ideas you may have. Already have an account?

LIR Coin Cell Charger |

This step is required in order to ensure a good connection when the battery is inserted. The chargerwill not damage the LiPo? I should clarify the equation in my earlier reply: Here is a review of the new charger module with a protection circuit: Some of the resistance values are clearly rounded and are not standard E24 values.

Sure, coin cells usually last a long time — but do you really want to buy new ones and throw the old ones out? Primary and Coin Lithium Battery Primer: Even though surface mount tabs dataheet available, these cells will be damaged if put through a surface mount reflow process due to the high temperatures involved.

Using the max rate of mA with ohms, one can do datasheef following:. UN transportation test The LIR series of secondary rechargeable lithium button cells dafasheet gives high voltage, long shelf life, and high energy density in a small cell. It’ll charge several 20mm type coin cell batteries.

Prices are subject to change, please inquire for current prices. Again — LIR batteries have 3. Most popular manufacturers and their models of batteries are given in the following table: Adobe Portable Document Format – No luck finding it tho. Leave a Reply Cancel reply Enter your comment here Unfortunately or fortunately depending on how you look at itthe charger I had ordered off Amazon didn’t work, so I decided to build my own.

Lithium ion Rechargeable (secondary) Coin Cells from PowerStream

Of course, the higher the resistor, the less charge current and thus the longer the battery will take to charge. Fortunately LiRs are affordable enough that you can afford to kill a few.

Typically you would charge at 1C i. Also note that manufacturers use both CR and custom designations. The datasheet suggests a linear progression datwsheet doubling the resistor value will halve the output current.

BR is very similar to CRm, except it uses carbon monofluoride as positive electrode, instead of manganese dioxide found in CR Presuming the table in the datasheet is valid. Does anyone know of a good writeup on rechargeable batteries?

I had the need for an LIR coin cell charger to power a few projects. Watch out for commercial coin cell chargers that supply mA. You are commenting using your Twitter account. With that formula, 33k would give about 36mA.
