How long does the Deli 1710 calculator battery last and what model of battery is it? 10

Deli this calculator uses 2pcs, ag13Coin cell batteries(or L1154, LR44 type coin cell batteries) power supply, and the replacement battery needs to be smallScrewdriver.

There is no problem with one year, Deli This model is 1710 multi-function function calculator is a calculator that can directly calculate functions, including basic operations, statistical calculations, function operations, fractional operations, ANS functions, etc., with a large screen double-line display.

240 functions with multi-step retry to solve various computing problems. Sliding protective cover, which can be split by itself, sliding up and down, front and back cover; The thin and light body uses a button battery, which is more portable and durable.

The calculator power supply uses an AC converter.

or battery, the battery can be recharged with an AC converter or solar converter. In order to save electricity, the calculators are LSI made using CMOS technology.

I don't know anything else, I'm not good at all. The new battery, used once (I'm sure I turned it off), put it for half a year, and then used it and it ran out. If I change the battery again, I used it again, and it ran out of power if I used it again.

It is used during the final exam of the university, and the frequency of use is once every six months, and the rest of the time is calculated with a mobile phone) Solar panels are the same as decoration, useless. The calculator bought 50. Every time I change the electronics, I have to find a master who repairs the watch to change, 10 yuan at a time, it's too worthless, I just threw it away.

The Casio I bought in junior high school also has no solar power, and it is used very frequently, and it still has electricity after nine years. In comparison, Deli 1710 is really bad!

3. Generally speaking, there are two common types of button batteries: rechargeable and non-rechargeable, including rechargeable lithium-ion button batteries (LIR series) and 3V rechargeable lithium-ion button batteries (ML or VL series); Non-charging includes 3V lithium-manganese button batteries (CR series) and alkaline zinc-manganese button batteries (LR and SR series).

4. The more common button batteries are AG3, AG10, AG13 batteries used for toys and gifts, batteries on computer motherboards, model CR2032 is used for CR2025 in electronic dictionaries, CR2016 or SR44, SR626 on electronic watches, etc.;
