CR1220 is a battery cell, also known as a lithium coin battery that comes with a high voltage of around 3V and encompasses an ultra-compact design, helping you get rid of the difficulty of buying two or three extra traditional batteries, saving both the cost and the space needed to adjust these cells in the relevant devices.

CR1220 is a lithium coin battery that is mainly used in high-powered devices such as keyless input devices, glucose monitors, heart rate monitors, and toys & games.

It comes in a cylindrical shape and may retain power for a maximum period of time. If it is spared alone for one year, only 1% of the total battery capacity will be discharged.

This battery is slightly different from CR2032 in terms of battery capacity, weight and lithium content, since it comes with a capacity of 35mAh with a weight of 0.8g and a lithium content of 0.006 grams, followed by a capacity of 285mAh, a weight of 3 grams and a lithium content of 0.109 grams.

It is important to note that there is no need for coatings or other foreign objects on the surface of terminals that could have a serious impact on the actual use or performance of this coin cell.

They can be designed using two methods: an extra mechanical tool, such as a screwdriver, is required to unlock the battery compartment, or two independent movements of the securing mechanism can be applied by a single hand.

These battery compartments come with the ability to hold different cells where the capacity varies depending on the size.

When do you need to replace your cr1220 battery in your canon power shot sx100 IS?

My Canon SX10 was instantly displaying a message to "replace the batteries" the first time I tried to take a picture, even after replacing the AA's with new adn verified strong AAs. I was almost ready to give up when I heard that it might have to do with the coin backup battery and not because of the AA's. I replaced with new CR1220 and that solved my problem.

How do you open the key fob to replace battery for Renault Clio 2004?

== == Description The key fob splits into 2 parts with a sliding action There may be an arrow embossed on one side of the key fob pointing towards the metal part of the key - this shows the direction this side of key will travel when you split the 2 parts. The metal part of the key will stay with theside of the plastic fob which has the arrow on it. The thicker part of the fob (which contains the battery - this was a CR1220, 3V in our case) will move backwards away from the side attached to the metal part. Method Put key fob in-between finger and thumb and push backwards it will split in two. No tool is necessary.


Can you replace a CR2032 with a CR1220?

Most likely not (No). They are the same voltage, but not the same size. The following specs are from Duracell's web site: http://www.duracell.com/en-US/series/electronic-batteries.jspx?utm_source=Google&utm_medium=cpc&utm_term=%2BCR1220%20%2Bbatteries&utm_campaign=Duracell_Search_Desktop_Category+Interest|Electronics+Batteries&utm_content=s95QccF16_20317950700_b_%2BCR1220%20%2Bbatteries:IEC: CR12203.0 Volt35 mAhSize (mm): 2 x 13 x 13LithiumNow compare that to:IEC: CR20323.0 Volt220 mAhSize (mm): 3 x 20 x 20LithiumThe mAh is milli Amp hours, which measures the strength of the battery against a load (how long it can last). The CR2032 is a bigger, stronger battery. I didn't know that before today.

Batteries for key remote for 1997 960 Volvo?

$10 WATCH BATTERIES! (Wow, I actually have an Answer to a car question.) Volvo remote requires CR1220 3V lithium batteries found in any jewelry store (If Brit go to the jewellery store). After checking EVERY auto parts chain I found...go figure...at the local WAL*Mart. Had to ask the sweet lady, who had just completed mixing a gallon of "St. Croix accent base" house paint, answering the public address announcement alerting to the need of assistance in the "fine jewelry department." Bless her heart...with a smile, she eased behind the glass case, unlocked a hidden safe containing the secret stash of timepiece batteries. (Apparently lithium batteries are worth more than the dazzling jewels Made In China.)
