JLCPCB Prototype for $2(Any Color): https://jlcpcb.com
Stripdown of some cheap Lidl Parkside 12V power tool batteries (with 30% off the marked price). The 2Ah contains three 2,000mAh cells and the 4Ah has 6 cells. These batteries are fully protected against over temperature, over charge and over discharge, but there's something important missing.

    Thanks, I hope you have answered my problem.
    I connect with a cable to my boat 12v lead acid battery, runs for ages.
    So far been using a very old 12v drill.
    Recently got. Parkside mini angle grinder, what a useful tool. It was marked + and – .
    Just got a multi tool annoyingly not marked, but I can see from you video which way round.
    The angle grinder I could just push a spade type connector over the contact. The multi tool connector is bent over at the end, probably needs soldering.

    They're junk I have several and they keep changing the fitting so they can't be used on different items.

    Hello! My question is how long do they keep their charge, that is, how long will it stay charged?

    Just noticed: on the battery it says PAPK 12V A1 Which means they are old type non-balancing. Although the package says PAPK 12V B1 which ARE balanced type! This is probably why they give them away on such action price. Manufacturing error.

    Hi Julien.

The parkside has plus/minus and and a 3rd connector. the Hitachi batteries has plus/minus and the following.C+, T, LS, T. V, LD How do I go about it? Thanks

    Good video Julian. Quick question, and perhaps you may not have the answer. But I have some older (2017/18) Parkside tools which use the 12V batteries however, when compared to the latest batteries, the terminals are swapped around. i.e. my battery has + on the left, whereas the new batteries have + on the right. Do you know, if I were to strip down a new battery and swap the + and – spade terminals with each other, so the terminals would then match my current, older battery configuration, would that enable them to work in my tools? Thanks
