[quote name='John-E-Retro' post='102035' date='Dec 10 2007, 09:57 AM']I have a 9V /18V battery low indicator, you can see a post about it in the retro forum [url="http://basschat.co.uk/index.php?showtopic=4862"]low battery indicator thread[/url] It's a circuit board about 1" square, currently. The way it works is very simple: * It sits there taking a tiny amount of current, a few millionths of an amp when the battery is good. * When the battery system (9V or 18V) starts to decline, but there is still some life, a high brigthness LED starts to flash around once per second. But again the power consumption for the LED is very tiny since the LED is on for just a few millionths of a second. The eye sees that and image retention of the human eye makes it seem to be lit for longer and can easily see the flashing. So unlike some systems, where a low battery LED is turned on full, which drains the battery much faster and may even take more current than the electronics, my unit takes on average, a few 10s of millionths of amps, still an insignificant drain to indicate the battery is low. Have them in stock £25.00, with black or chrome LED surround. John[/quote] Sounds good, will have to take the electronic cavity lid off to see if the unit will fit, there's certainly no room in the battery compartment.

Can anyone tell me how to edit a post title for example when an item has been sold how do you change the title to reflect this? Thanks John

Thanks for your posts, I'll check later to see what jack I have, momo or stereo. I can print this off and let the local technical bod have a look. Will let you know what happens, as I can't be the only one that gets this problem

Thanks for all your help, you can't beat a good education! lol

Hi Dave, Can you help me please, I have a Shuker bass with 18v electronics/pickups and my main nighmare situation is for the batteries to fail in front of a theatre full of people. To that end I change batteries way more often than I need just to be on the safe side which is getting a little expensive. Is there any way of fitting anything to the bass, maybe an LED to the rear of the battery cover which would identify when the batteries are getting low? I know that a 9v system is available at [color="#0000FF"][url="http://www.guitarelectronics.com/product/PMTLBAT/9_Volt_Low_Battery_Indicator_for_Active_Pickups_Electronics.html"]http://www.guitarelectronics.com/product/P...lectronics.html[/url][/color] unfortunately they do not do an 18v version. Help would be much appreciated. John

I am a late fourties musician who has been a member here for a while but probably due to my age find it hard to understand the abreviations. For instanace PM'd, presumably means private mail???? What the hell does BUMP mean, I really can't work that one out! Any other abreviations that someone can explain would be really helfull and would make an old man very happy instead of a happy man very old!! Ta John
