Replacement battery packs

[GB]

I need a replacement spare battery for my drill and I found this at Amazon surprisingly cheaply. (£26.) I thought they tend to be a lot more than that - about double?

Oops!

Might not be original quality/spec - no telltale yellow bits in the photo. A good clue as to cell capacity might be if the weight of the packs are similar. I've heard stories about smaller cells being fitted in low cost replacement packs.

Good Luck

The reviews are good. I agree that the cell capacity might be lower, but this is often due to cell characteristics not size. Just replaced a couple of Dell battery packs (both different suppliers) with units from Amazon. Works adequately with a couple of hours life. Same as the originals.

I recently bought 2 x Makita replacement (i.e not genuine) 3.0Ah batteries from ebay for less than half the price of genuine ones. The seller had decent reviews, and for the price thought it would be worth a punt. Seem OK so far after a few cycles.

I bought one when one of my originals started to fail. It almost matched the originals for performance when new, but by the time the other two were past it, so was the "new" compatible battery. In the end I had to shell out £150 for a 3 pack of original Mak batteries.

Did you consider getting the originals re-celled? I have a Ryobi drill with two 18V batteries that are past their prime, was thinking about trying one of the re-celling services or re-celling them myself. They are held together with screws, so it shouldn't be too hard to do.

Big problem is finding decent quality cells at a reasonable price. These things vary in quality perhaps more than anything else.

Sanyo used to be the one to go for - although they might cost more than a genuine replacement maker's battery pack. But I'm not well up on the current market.

[John Rumm]

I did look at it. Alas the price of decent cells was more than the OEM battery price.

I have 4 of those Ryobi One+ batteries that are all dead, if you find somewhere to get yours done at reasonable cost would you mind posting here. I had a look inside but the cells seemed far too securely attached to each other to simply remove and solder in new ones.

[Dave Plowman (News)]

They are normally connected by welded tags. Soldering direct isn't reckoned to be a good idea as it heats the cell too much. Spot welding less so.

You can buy 'tagged' cells which have welded tags which you then solder to.

Yes, the ones I have are One+.

Had a good hunt around ebay and Amazon. Ignoring the obvious poor quality Chinese knockoffs, the lowest going price seems to be in the region of 50 quid each. More than I want to pay, really.

They went in, so they must be able to come out :-) Not looked in mine yet. 18v suggests 12 cells, presumably C size?

[John Rumm]

Usually the so called "sub C" tagged cells.

[Capitol]

Worth looking out for 18V(or higher) NiCd ) battery packs on the clearance shelves (AIUI these store happily at 0V). They all use sub C cells IME and can normally be reconfigured/persuaded to fit into other cases. One of mine uses an 11 cell bottom with a 12th cell on top. I find soldering these cells with a very hot iron and acid flux seems to work satisfactorily.

[Capitol]

Also forgot to add that Parkside(Lidl) 18V batteries are available for a very nominal sum from DES UK ltd who have good service.

[newshound]

I re-celled one of my Ryobi's without too much difficulty.

[Mike Faithfull]

If you don't wish to do it yourself, you might try Multicell International Ltd

I have used them several times over the years, most recently for re-celling (if there is such a word!) two battery packs for my Hitachi drill. I don't know how they get the case apart without breaking it and then resealing it without leaving any evidence, but the end result seems "good as new".

[PeterC]

1.2V each, so 15 cells.

Ta. I'd thought 12 x 1.5v, forgot they're rechargeable.

[D.M.Chapman]

Interesting - any clue as to price?

I've 3 12v Makita bats that are pretty knackered - still kicking myself for not picking up one of the site sets that screwfix were flogging off cheap a couple of years ago just for the batteries :-(
