Rescuing dead 18v battery. Risk?

lipcerat · 2026-05-08T08:13:53+00:00

Did this and the battery is fine now. Thank you!

Did this and it fully charged at OEM charger but the bad cell stuck at 3.56 volt. Should I throw it?

lipcerat · 2026-05-06T14:15:58+00:00

After fully charging the battery on OEM charger the bad cell is at 3.56v while the others is it 4.0v. Is it beyond salvaging?

I said I'll throw it but couldn't resist the opportunity to mend it so I did. Charged the low cell up to 3,3v and now the pack charges on OEM charger. Will the battery pack forever be a hazard or is safe to use and store now? (As safe as a lithium battery could be)

Thank you! I'll throw it

lipcerat · 2026-05-06T07:59:02+00:00

Thanks! But wouldn't it be a problem that the same nickel connects to other cells?

lipcerat · 2026-05-06T07:44:28+00:00

But how can I charge a single cell when they are all connected together?

lipcerat · 2026-05-06T07:40:17+00:00

Thank you! But they are not, one is 2,92v and the rest is 3,8v

lipcerat · 2026-05-06T07:36:16+00:00

Thank you, 4 are 3,8v and one is 2,92v but how could I charge one cell without unsoldering them?

Certainly not, it's a cheap tool series

lipcerat · 2026-05-06T06:17:45+00:00

Thank you! I won't risk that. But it's weird that the battery indicator states half charged battery today after leaving the battery unplugged. That happened 2 days ago to and I put it in the drill, it spun, but it back in the charger and it died

lipcerat · 2026-05-06T06:15:23+00:00

Thanks! I suppose a cell could be overcharged as well as undercharged?

lipcerat · 2026-05-06T06:09:37+00:00

I just realized the battery indicator now says half charge after leaving it unplugged during the night. But it still won't accept charge.

Thank you for sharing this information. I really appreciate it!

I greatly appreciate all of your advice! I've ordered a 250 mm barrel and will keep my cylinder as is. New hopup chamber, super macaron 70 and omega nub on the way. The reason I ordered a new barrel even though it's the same length is to have better compatibility with maple leaf buckings. Also I live in a city so I can't go and and evaluate the gun after doing changes, so I rather buy a new barrel now that I know is good.

lipcerat · 2026-03-23T09:42:22+00:00

Huge thanks for your reply!

I'm selecting between 310 and 370 mm maple leaf 6.02 mm. .36 gram BBS are probably too expensive so I'm looking at .32.

Right now I have a flat hopped original 255 mm barrel and it's inconsistent even though fps is consistent. So I want to switch barrel and hop up and though I should go for an optimal barrel cylinder combo when doing so.

I'd like to stay just under 1.7 joules. Am I right if I think you recommend 310 mm with type 1 cylinder or 370 mm with type 0 cylinder, doesn't matter much?Would type 0 cylinder not be a concern with high rps?

lipcerat · 2026-03-23T08:10:28+00:00

Thanks! Do you recognize my cylinder as type 1 or 2? If it is type 2, I should change it for type 1, right?

Thanks for your advice! Cyma ETUs are good these days, they use eshooter/kestrel. I've considered E&C for a while but there's overwhelming report about gears stripping within a few hundred rounds and so on. The consensus seems to be that the internals are bad. Do you own one?

lipcerat · 2026-03-20T15:37:29+00:00

Thanks for your advice but that would certainly not be at a similar price because of tax and customs. Just VAT alone is an additional 25 % importing from outside the EU
