    I've heard of guys using battery keepers too. A tool like a simple leak detector which needs to be looked after on a daily basis that doesn't get used on a daily basis is not for me.

    I've also wondered if the battery is fine it just needs to be cycled more. It could be fooling me with the green charged light.

    We had a similar thing with the kids RC car. I got used maybe ten times than sat on a shelf for a long time. We went to use it after the long period of inactivity, charged up the batteries and the car fizzeled after a very short run. Took to Google and was recommended to run the battery through several charge and discharge cycles and it would probably come back to life which it did. Every cycle got better and better.

    Just this last time here with me checking voltage and when the lights change it is holding charge longer. Before I would plug it in and it would show green... good after a minute or so. Take it off the charger and it would show red... low after a minute or so. When I left it the charging cycle had extended several minutes.

    This is a $500 leak detector with a crappy $10 battery. Seems like it was designed to be a bench tester and not something for the field. Luckily the battery design issue looks like something easy to redo until a better handheld comes out.

    Different types of batteries have different charging and 'memory' cycles...

    The battery in my H-10 (not PRO) is a sealed lead acid... they prefer to NOT be deeply discharged, they loose capacity when they are.
    A NiCad or NiMHd battery (cordless tools before LiOn) were the opposite... keep them charged... and they lost their memory of depth of charge (fizzled quickly). Cycle them repeatedly and they get their memory back.
    LiOn batteries do not seem to have much memory issues... however NEVER discharge them below 20-25%... as it damages the internals of the battery. Little known fact: taking a LiOn battery too low... is the main cause of battery fires. The internal damage from repeatedly taking the battery below 20-25
    % is what causes the battery to heat up and start on fire.

    I can't understand why they went through a redesign and didn't use a Li-Ion battery pack.

    Makes no sense. Smaller, lighter, longer shelf life, etc.

    Crazy. It's the only reason I don't own one.
