Dead Bosch 18V ProCore 8.0ah Fix by Jump Start

It seems they don't tell you everything - the videos that show you how to jump start a dead battery. Most suggest you only need to jump start for a few seconds to a minute. Mine needed much longer!
Battery management might differ between brands I guess and so, folk only speak to what they have experience of. That's why I put this video together. Not just for Bosch battery users but, for anyone else who tried this technique and maybe thought they'd failed but just needed more time.
It appears to be my Bosch GAA 18V 24 USB charger that over-discharged the 8ah Procore. A little bit my fault too perhaps. In a case of needs must, I put the Procore onto the GAA with just one bar left on it's 5 bar level indicator to charge my camera. It could be the old GAA's like mine (11 years old now) don't have as sophisticated battery management as the power tools, so it ran the battery dry.
Anyway, the Big Procore was rescued in the end. Really didn't want to fork out £100 on a new one!

I have always been a bit suspicious of these battery videos in the past. However, coming from someone whose opinions I trust, has set me straight. Thanks for the info 😇

That's kind of you to say mate. Thanks. I was suspicious of it myself tbh but, as it would've cost around £100 to replace that battery, thought it worth a try and sharing the experience 👍

Thanks for sharing your experience.

Cheers. Wasn't convinced it'd work tbh, but here we are.👍

Awesome video, both 12 & 18V USB chargers are junk. Bosch should redesign both. Thanks for the video.

Cheers. They are a bit rubbish. Mine just lives on the tripod feeding juice to the camera. Useful for that. Not much else.👋

I have two old "cordless" drills with power cords attached to battery cases and AC -> DC transformers inside (instead of battery cells). Not very convenient, but manageable, and you don't need to worry about battery health.

An old colleague of mine had an old Hitachi drill a bit like that. Had batteries, but also a pack that would slot in with attached power cord for when the batteries were dead. Early 90's model I think. When I worked onsite, anything cordless was a godsend. Now I work out of a workshop, I'm not as bothered. In fairness though, battery packs have usually lasted me extremely well over the decades.

@@BischBaschBosch a have an idea of having batteries on your work suit, and gloves with electrical contacts, and tools with electrical contacts on its handles. So when you pick up a tool, you power it up. Just an idea. That should be super convenient.

Can you use a bosch battery to jump a dewalt one? Always enjoy your informative videos

@BischBaschBosch Ай бұрын

Cheers. I would say a cautious yes but, if you have a volt meter, I'd check the +/- terminals with that first. If they both read 19-20 volt and very low amps, it'd probably work. Not sure if it's a flexvolt dewalt battery though.

Thats really interesting. Think ive thrown five out in last year, wish id have known about this move. Mind they didnt owe me anything some being 15 yrs old or so. I have a 5ah battery thats not had a lot of use but only will charge up to one of the three lights. Any thoughts ?

@BischBaschBosch Ай бұрын

Cheers. Yeah, i think when a battery is over 10 years old, it's safe to say it's done it's service and recycle it. If you've one that won't charge fully, it's usually down to one or two of the cells becoming unbalanced - dropped voltage or some such. This can be sorted to some degree but you need a fancy bit if kit to top the individual cells back up to match the good ones. For most of us, this means it's headed to the recycle centre at some point 🤷‍♂️

@BischBaschBosch brill thanks for the reply.

Think I may have recycled one of my batteries too early. I’ll know better next time, thank you!

@BischBaschBosch Ай бұрын

Always worth trying before recycling I think. Especially as it's so easy. 👍

I’m a Milwaukee user and the give you a warning like a tool stop to let you know its time to charge but good to know thanks

@BischBaschBosch Ай бұрын

Cheers. Like Milwaukee, just about every power tool lithium battery manufacturer has a cut out on their batteries to prevent over discharge. They just stop when needing a charge. On a rare occasion though, a piece of kit - older or more basic accessories - can lead to slight over discharge, shutting the battery down (like mine). Same can happen if a battery has a bad (unbalanced) cell too.
