| How do you protect your handheld meters from battery leakage? |

Apparently (as reported elsewhere on this forum) the Brymen 235 will not function properly (shows an error) if you use primary lithium cells. So there are at least a few things where this is a problem. I haven't run into any myself. |

Problems with the high initial voltage of primary lithium batteries have also been reported for the 121GW as I wrote before: --- Quote from: alm on September 18, 2022, 02:00:06 pm ---The initial voltage is higher than 1.5V and can cause problems in some devices, like the 121GW ;). --- End quote --- So yes, the higher voltage matters with some meters. |

Hmm, perhaps those that do have an issue are optimized for better use with NiMH? I wonder if the Brymen 726 has the same issue? I have the 726 but I don't have enough of the Lithium batteries to try. In other equipment I have I have never had an issue. |

I can say one thing for sure, NEVER use Duracell alkalines, they WILL leak, positively the worst battery on the market. My preference is Panasonic or Varta, so far, they have never leaked. Intuition would suggest that cheapo batteries that are supplied with devices should be the worst, and although I never trust them I've known them go for 6 and more years, still have life and not leak! In fact, I've just had to borrow a D cell from a big 4 cell torch I bought in 2016 from Aldi. needed it for an Avo 8. Not only have they not leaked but despite having quite a few hours on them, they still have a healthy terminal voltage and short circuit current! The brand is Activ Energy, made in China, which I've seen in a number of Aldi products. So, surprise there! |

Used it only occasionally and forgot what batteries it had. When I looked in a few months ago, found out they expired a decade ago but still worked just fine. Unlike Duracells which leak in unopened package. |
