so, how is battery life on the rechargeables versus alkalines?

I run the Beyer MV100 with KM140's and can get 5 hours out of a pair of alkalines, before there is gain loss.

That Amazon link is to the Powerex non-LSD version of the 9.6V (white case with yellow lettering).
The Imedion LSD version of the 9.6V has a black case with grey lettering. 



Both are manufactured by Maha.

Here's the specifics on the Imedion version at Thompson Distributing- http://www.thomasdistributing.com/Maha-Imedion-9V-96V-230-mAh-Low-Discharge-NIMH-Rechargeable-Battery_p_2455.html

Here's their package of charger + 3 Imedions, otherwise same as the Amazon deal- http://www.thomasdistributing.com/MAHA-MH-C490F-9-Volt-9V-Battery-Charger-with-Three-Maha-Imedion-96V-230-mAh-Batteries-with-World-Adapter-and-12V-Cord_p_851.html

Thanks Lee!  I ordered the Maha charger + 3 Imedions!

These Maha  rechargeable 9v's have saved me thousands of $$ in the years I've been using them.

They are not as reliable or last as long as Duracell Copper Top's but they also don't cost me $3-$6 per show which is what I pay at Costco or Target for Duracell's.

How about this one?
http://www.amazon.com/EBL%C2%AE-Battery-Charger-Rechargeable-Batteries/dp/B00HV4KFSA/tag=metaefficient-20
Anybody tried this Li battery, probably one ore 2 cell electronically raised to 9v (guessing)
Unfortunately they do not ship to europe.

Not sure how everyone stores their 9vs. This is the first time ive messed with them since i first started taping. I found this on amazon and i love it. Batts are secure in the holder. Low enough nothing will touch the terminals while in the case

Nice.  Put them in there the other way (upside down) and a terminal short is even less likely.
[edit- oh wait, maybe they won't snap in that way, the case ending up taller by the height of the terminals, and the plastic latch no longer at the right height.]

Beats sticking a small piece of gaff tape across the top, which is what I do.

I know this isn't 9v related, but I have had this Maha Powerex MHC-9000 charger for over 5 years now, and it does an AMAZING JOB of charging and maintaining my AA/AAA batteries! My old Energizer 2300mah NIMH AA's lasted over 5 years because of this charger! And never use another bad battery again! This will tell you within 10 minutes if the battery is bad or not! But most importantly, it has a "Break In" function, that charges/discharges the batteries VERY SLOWLY, so that they can reach their maximum capacity after that :)

I wanted to get some 9v NIMH batts back in the day when I had my Lemosax and LB, but never took the bite! I looked high and low for a charger similar to the Maha MHC-9000, but for 9v batts, and I never found that similar 9v charger, if it even exists :) Something with that "Break In" mode would be awesome for getting the max capacity from your 9v batteries! Sure, you could just cycle the hell out of them, but that "Break In" mode is equal to probably 10 cycles at least IMO!

I've been using standard 9v energizer or duracell's in my littlebox v1 (the 2015 edidtion).  They read about 9.25-9.3 new.  Any reason the powerex 9.6v wouldn't be a good option?

Which 9v rechargeable would you all recommend for the LB 1.0 2015 edition (fast or slow discharge)?

I like the idea of moving to rechargeable for my batteries so I am not recycling as many + saving some $$$$$.

Thanks,

LSD (low self discharge) versions of NiMH batteries have a bit less total capacity, but hold their charge for much longer.   A regular NiMH will have less capacity remaining than an LSD about a week after re-charge and be effectively dead in about a month, whereas LSD NiMH supposedly holds usable charge for about a year.  That makes LSD batteries more reliable in the short term, and I believe also gives them a longer usable life-span making them more reliable in the long-term as well.  However, I've no evidence for the improved life-span and long-term reliability claim other than my own anecdotal use.

For me that minor reduction in total capacity reduction is totally offset by these other advantages of the low self discharge versions.

NiMH "9V" batteries have a slightly different voltage than standard alkaline or carbon-cell 9V batteries.  Standard NiMH "9V"s measure closer to 8V when fully charged.  The 9.6V measures around 11v fresh out of the charger, and drops to about 10V by the time of use.  They' measure around 9V or a bit less after use.  For devices designed for alkaline 9V batteries, where performance may suffer if not supplied with sufficient voltage, the 9.6V NiMH may be a better choice than a nominal 9V NiMH.

MAHA offers their 9.6V NiMH in both regular and LSD versions.  The non-LSD version is branded Powerex and has a white case.  The LSD version is branded Imedion and has a black case (see the photos posted above).

Thank you GutBucket, I will investigate the 9v LSD for my LittleBox..........
