Hohm BASE combines easy 4 button layout with features of capacity estimation and Battery Doctor which discharges down to 2.8V, and back up to a full 4.2V (1.4V spread).  It monitors mAh (capacity) in both discharge and charge stages.


Its primary purpose: put the “giddy up” back in batteries. Some may refer to the Hohm BASE as battery Viagra®. Utilizing both CV & CC (constant voltage & constant current). Works best on older and/or heavily used batteries. Hohm Base emphasizes on precision, efficiency, consistency, and safety. It is a quad-channel independent lithium-ion battery charger with universal algorithm to charge multiple battery chemistry platforms. It has an advanced STN display to make viewing from any angle possible.

  1. from Marietta, MS

    I don’t understand it, I don’t need to neither. All I know is it brought back 3 batteries I thought were dead forever.

  2. from Kailua, HI

    not many options here in Hawaii, so often we have to research on the internet. Tried 2 brands. This is the one I’m keeping. Does everything I hoped. I particularly like there is various fittings built directly into the the plastic slot where the batteries go. Makes it line up perfectly with any battery I put in it.

  3. from Arlington, VA

    Love this charger! I wish it had displays for each slot instead of having to toggle in-between the 4. Especially because the default charge amperage is .5 so everytime I plug my Holm Life batteries I quickly have to switch and change the setting. If I’m too slow I just have to remove the batteries so it recognizes the battery, which isnt a huge concern, but definitely a downside. The real problem I have is this charger has a tendency to tear the wrappings of my Holm Life batteries at each end of the battery. 2 of the slots springs seem to be tighter so it’s more difficult to fit the batteries in.

    • Hi Slipgator, Thank you for your feedback. Sorry to hear about your experience. Please use your finger to support the charger’s slider from snapping back into place to prevent any contact to cell/battery. This will keep labeling intact. Or you can remove battery by lifting positive side out first and hold it so the slider goes back to resting position. IF EVER the label (wrap, skin, sleeve) has any nick, tear, damage of any sort, please send directly to us here at Hohm Tech so we can replace it. Your safety and experience with product reliability is important to us.
