marconi 2031 battery

(1/1)

radiofanman:
I want to buy a new rtc battery for my marconi 2031 but the manual just says a lithium battery, can any one tell me if its a rechargeable or non rechargeable one ie a 18650 3.7v lithium.Sorry about the basic question but the sig gen is buried under a lot of gear and I only want to get it out once to change the battery. ::)

SeanB:
Generally a non rechargeable one, with diodes or a power management IC to power the SRAM and a RTC if used, and provide the write protect and CE logic needed to put the RAM in a low power state when power is off.

You can use a rechargeable one, but will need to have a method to charge it separately.

radiofanman:
ok thanks I think i will get a non rechargeable as I dont want to keep pulling the unit out,I think they last a couple of years anyway. :-+
