Tagged: BT Connection Battery Leak

1. Still having problems connecting via BT to one of my Android devices, I have found that all I have to do is toggle or turn the BT off on the Adroid device and then the Moosimeter will typically connect without a problem. So if you are having Android BT connection issues, try to power the BT off and on and see what happens.
2. Unfortunately I drop tested my Mooshimeter from about 4 feet to my brick steps. The fall may have been partially slowed by a set of test leads I was holding on to, but I do not think I was able to help much. Walked out my front door with the Mooshimeter, Tablet, Test Leads and an interface for the car. I have 2 steps down. The Moosimeter rolled out of my hand and BOOM on the brick step one below where I was standing. Well the outcome was GOOD. The poly-carbonate case had on a few VERY small dimples, I had to look 3-4 times to even find any damage to the housing. Overall the case is really tough!! A rubberized holster would be a welcomed accessory with some way to hang the meter.
3. Batteries may not like the “pulsed” behavior of the meter?? I replaced the factory shipped batteries when I was having problems with the firmware update and endless loop. This was in mid Dec as I recall. I usually put my meter in Shipping Mode when I am not using it. After my above drop test I was looking carefully at the case looking for cracks or damage. I noticed the base of one of my batteries had appeared to have leaked with crystallized electrolyte around the negative end of one battery. I removed the batteries and only one had leaked. No damage to the meter. Checked the Voltage on both batteries, both has slightly over 1.3 Volts.
Just thought I would put this out there for others to look closely for battery leakage. Maybe this was a one off problem, maybe the pulsed nature of the meter is stressing some batteries in a strange way. For the record these happened to be Rayovac Alkaline batteries from a larger pack and this is the first one that I had any problems with. The build date on the batteries was May 29, 2013. So not quite 4 years old, not the newest batteries, but I have many still in the pack.

#2: Take a look at another post titled Rubber Protector Case. Some ideas there. I just added a comment there so I won’t duplicate here.
#3: Well, I recently happened to do some investigation into alkaline battery leakage after one of my AA flashlights was trashed from a leak, so I thought I would provide my opinion. Turns out all alkaline batteries are prone to leaks and the popular one, Duracell, is no exception.
NiMh rechargeable batteries are not very prone to leaking. It is very rare. And most recent NiMhs have a long charged shelf-life (ie slow discharge rate). I am in the process of moving most of my AA devices to eneloop NiMh batteries. The mooshimeter works well with eneloops, but the app battery display is 75% or lower through most of its useful runtime since NiMh starts with a lower voltage (1.2V) compared to alkaline (1.5V). I can’t speak to a comparison of mooshimeter total run time with NiMh vs alkaline.
However, if I wanted the absolute longest runtime, the best AA on the market, and price was no concern, I would investigate Energizer Lithium (non-rechargeable) AA batteries. Warning: The initial no-load voltage is 1.8V so two of these are right at the upper limit for the mooshimeter. Before I would try it in my meter, I would ask James if he had any experience using these.

#1: I can’t comment much on this except to say I sometimes do the same thing myself. Android BLE is just kind of flaky, and I’m afraid it’s flaky on layers below the application layer. The good news is that it’s been improving with every new Android version. 4.4 was a mess…
On the other items: I agree with Duane on all counts. And I’ve run a Mooshimeter on 1.8V lithium AA batteries without a problem before.
