JPAC Posted May 11, 2009 Share Posted May 11, 2009 Not sure how long it would take me to use 30 batteries but something to bear in mind, thanks. I'll check out the pound shop, I know the manager of our local one, I'll check what they've got. That makes sense about the voltage drop, I wonder if the lithium ones would be OK, they are 9.6V, 0.6V higher than normal. I have a feeling I'll forget to unplug the cord and drain the battery.

You can get the top brands for around £6 each or pretty good ones from Aldi for £1.99 when they are in stock. It's a no-brainer - and you'll be looking after the planet.

Do you keep your bass plugged in all the time?[/quote] yes - I don't know about Stingray but generally an alkaline PP3 should last months at least. I would have to say that NiMH rechargeables do tend to drop their voltage / power more rapidly than alkalines and more so as they get older. It depends on lots of things though - pattern of use / temperature etc. and is a whole topic in its own right. btw they also tend to lose charge more quickly when 'in the drawer' so don't bank on those ones that you charged up the other week still being okay. Various brands tested but I can't see big differences between them. Views welcome. I use mains power unless it's not feasible ( or phantom for BDDI going into desk ). Takes away the 'left it plugged in' scenario. Quote Link to comment Share on other sites More sharing options...

However, it is true as you say that they 'self-discharge' over a period of between 3 and 6 months. You should therefore top them up just before you use them and remember that you will need to fully recharge them in 6 months at the latest whether you use them or not. There is no point in using them in things like clocks (or basses for that matter), where an alkaline normally lasts for years. Having said that, alkalines usually last a year in some of my meters, but I have a habit of forgetting to switch them off. That's where rechargeables really come into their own.

alexclaber Posted May 12, 2009 Share Posted May 12, 2009 Conventional NiMH rechargeables self-discharge far too quickly to be a good idea in basses. However the newer 'Hybrio' ones that are fully charged when new are very good and have almost zero self-discharge (about 10%/yr) - I gather they are now available in a PP3 size. I've been using the AAs for a while and am very impressed. Alex Quote Link to comment Share on other sites More sharing options...

I have a Pentax Optio S30 that I use infrequently, and it seems to be really sensitive to voltage, because I only need to leave a pair of NiMH batteries (AA) in there for about two weeks before it gives me a "Battery discharged" error when I try to turn it on.

Zoe_BillySheehan Posted May 13, 2009 Share Posted May 13, 2009 Morrisons have been selling the energizer 9V for Buy one get one free, or Asda 2 for £3 or something. but yeah.. definatly worth buying the quality ones rather than the cheap rubbish when it comes to batteries.

JPAC Posted May 14, 2009 Share Posted May 14, 2009 (edited) Had a look round today and the worst prices for Duracell are about £6.50 for ultra, £5.50 for Plus and most ask £3-£4.50 each. In Maplins they told me Uniross have gone bust and any batteries for sale will be clearance, had a look on the net and there's still plenty for sale. [i] news today "Eveready is looking to acquire a minimum of an 80% stake in Uniross for $13.65 million." [/i] Pound shop had three Procells for £1. Looked different than the ones I've seen before. I think I'll go for the Uniross Hybrio PP3 with charger for £11.99 inc Vat delivered, unless anyone knows a better deal. If I don't use the bass for a while it should have a little juice for an hour or so, if I leave the plug in and the battery dies, just charge it up again. Not sure if they are anti-leak. Thanks for your help, John. Edit: plug not jack Edited May 14, 2009 by JPAC Quote Link to comment Share on other sites More sharing options...
