Battery Replacement for Beard Trimmer Moser Neo

[singhtel]

hi , I have just removed the rechargeable batteries of my beard trimmer to replace them, I did a search on the net but couldn't find anything similar to this and am attaching a few pics, hoping someone can advise where I can purchase a battery replacements from,
They are two NIMH batteries joined together 1.2V each with tabbed connectors, 1800mAh - see attached photos,
They are joined on one side, and they have hooks to plug into the trimmer (see attached photos 2,3,4)
Note the first photo is that of the beard trimmer to which the batter gets plugged into


Thanks for your help..

They are standard AA sized NiMh batteries, exact ones here if you need a lot:

GP Batteries GP180AAH AA Rechargeable Battery

The GP Batteries GP180AAH is a flat top 1800mAh AA cell. These high capacity batteries are commonly used in battery pack production.

The connections are up to you though, for repair purposes you could remove the existing connections and spot-weld or solder them to the new cells.

The connection across the bottom appears to be a resettable fuse, and again should be swapped over.

thanks, is there anywhere I can get these readily available with the connections fused in

I would imagine possibly as a spare part from the beard trimmer manufacturer?, I wouldn't imagine it's a standard fitting, and is something they custom make. The link I posted above is to a company who assembles custom batteries for manufacturers etc, but obviously they don't do so in small quantities.

is there a site where I can see how to solder these in? also at one end of the batteries is a hook, are they easy to take off and insert into the new batteries?

They are spot welded on, you can gently prise them off, file them flat, and then solder them (or spot weld) back to the new batteries. We used to solder such batteries at work, until I ordered a small spot welding machine - if soldering them, then make sure the ends of the battery are clean, use abrasive paper to clean them up, and then tin the battery ends before soldering the terminals, and fuse, to them. If you've got some liquid or paste flux, applying that to the ends helps as well.

Try and put as little heat in the batteries as you can, use a hot iron (with a decent size bit) for a short time, rather than a cooler iron that needs applying for a lot longer.

Thanks for the feedback, I can't spot weld them and tried to solder them, . and got the bottom plate soldered to each other but unfortunately the tabs with hooks in the 2nd image broke off, these tabs plug into the beard trimmers circuit(first image), any idea where I can purchase such connectors from, searched through a lot of sites but couldn't find these as the spare parts available,
