Hey everyone, how do you protect you handheld meters and other devices from battery leakage? I've recenetly experienced another set of energizer AAA cells wet themselves. Putting batteries into my meters before and removing them after each use is kinda impractical. Most of my meters require at least one screw to be remove to access the battery and most of them only have plastic screw threads which would probably wear out quickly, even if you are careful and try to reuse the old thread every time you put the screw back in. For the better meters it is even more of a hassle because you have to remove the silicone sleeve first. I wonder if there are Li-Ion packs available, that fit into a standard 2/3/4 AA or AAA battery compartment. How do you protect your stuff? |

There are AA li-ion batteries with usb charger and 1.5V switcher mounted inside the battery body (with up to 1600mAh, but I would be a bit skeptical about that). |

I use low self discharge (e.g. Eneloop) NiMH batteries in all my equipment that takes AA/AAA/9V batteries. No problems with leakage, and battery life is fine. If I wanted more battery life or low temperature performance, I'd look at primary lithium batteries, but they are expensive and you need to check if your equipment can take the slightly higher voltage. |

I use LSD Ni-MH or Ni-Zn for AAA and AA, and Li-ion PP3's. Even in stuff like remote controls. If I could use rechargeable AG13's I would. |

Unfortunately we don't seem to have the Fenix brand here in Europe. What is available here seems to bei either no name or brands I haven't heard of. Does anyone have experience with one of those Brand (e.g. Hixon, Hakadi, Kratax ...)? --- Quote from: alm on September 18, 2022, 10:04:48 am ---I use low self discharge (e.g. Eneloop) NiMH batteries in all my equipment that takes AA/AAA/9V batteries.

They died pretty quickly within a year or so. They didn't leak but also didn't charge any more. I guess that was due to the memory effect and the way DECT phones are used (discharge only a fraction of the capacity during a call and put the device back into the charging station). In handheld meters this will probably be less of a problem. However I'd expect the lower voltage to be a problem - For instance I have a meter that runs on 3V (2 AAA in series) with NiMH I'd only get 2.4 V at best which I expect to be trouble. Do you have any experience how battery powered test equipment deals with those lower voltages? Also looking at the amazon reviews Eneloops (Or NiMH batteries in general) don't seem to be 100% leak-proof either. --- Quote from: AVGresponding on September 18, 2022, 10:13:14 am ---I use LSD Ni-MH or Ni-Zn for AAA and AA, and Li-ion PP3's.

Can you recommend any brand and good charger for the Ni-ZN cells? I guess your regular Ni-MH charger won't work for those. |
