Introduzione
Col passare del tempo, il pacco batteria all'interno del tuo aspirapolvere manterrà meno carica e potrebbe smettere di caricarsi del tutto. Puoi risolvere questi problemi sostituendo il pacco batteria.
Cosa ti serve

Svita le sei viti a croce Phillips #0 da 2 mm esterne che tengono insieme le 2 metà della copertura bianca.

Scollega il cavo rosso dal pacco batteria (tiralo, non ruotarlo!) e fai lo stesso per il cavo nero.
This is removing the battery pack, not replacing the battery pack. That would be the interesting part.
Okay then:
Step 7: connect replacement battery pack to the battery terminals, taking note of polarity.
Warning: if battery terminals are accidentally connected incorrectly in reverse polarity (i.e. black to red and vice versa) damage to the battery and device, and user injury may occur.
Step 8: Reassemble device by following disassembly instructions in reverse order.
Hope this helps.

Seems like a pointless excercise, as the original batteries are no good.
I have had two 15.6 DBs, including a warranty replacement, and maybe got 5 uses out of them before the batteries failed.
There are tips on replacing with NmH batteries on line, or get a new one with Lithium ion batteries.
I will second that. NmH batteries and maybe the charger are the problem, so it is pointless to thro more batteries in there.
Hi Peter, thank you for the above comments. Do you have any idea where to buy a NmH replacement battery ?
1. For the disassembly methodology, it would be better to remove the normally removable components first before removing the screws holding the motor/battery case together.
2. The link provided for battery replacement is no longer valid. Since online retailer merchandise web pages change frequently and therefore links soon go out of date, it’s best to search for a battery replacement at the time needed rather than provide a specific link. Be sure to search for your exact vacuum model number since the installed charger has to be compatible with the battery type.
1. Despite understandable reservations as to quality, eBay often has a good selection of replacement batteries. Preferred sellers are US -based as opposed to offshore and those that allow returns. Specification is crucial: type, (e.g., NiCd, Li-on), voltage, dimensions (new battery must obviously fit into vacuum case), battery terminals (type must be compatible with existing wiring - check against seller’s provided photo). If in doubt, send seller a question via eBay.
2. Check manufacturer recommendations for charging. Leaving a device permanently on charge when not in use may not necessarily be the best method for optimum battery life.

Replace the ni-cad pack with a li-ion one. 4 each 18650 cells will give you 14.8vdc. If you use/buy a computer battery you’ll have enough cells for 2 repairs. Get the highest capacity cells you can, i.e. 2.6ahr or higher. Solder them all in series, charge it up and listen to it SCREEM. Works for me. (Reason for computer battery is the quality of the cells and they have tabs to solder to) mikey
There is a resistor there so the higher voltage will cause the resistor to melt. Did you receive your EE tech degree at an ITT school?
Whatever the componentry there is always a reasonable overvoltage margin. Mikes post should be fine.
I would be worried more about the charging aspect. It looks like a simple voltage divider circuit and a NPN transistor in the area of the charging connector. My guess is that it is comparing the pack voltage to supply voltage and gate opens to charge batteries. VERY rudimentary design, and I am an EE. I thought about trying to upgrade this to Li-ION or LiPO, but decided to toss it instead. LiPO are also fire prone while charging. In a perfect world, all these consumer handheld devices would use a common removable battery pack so we could get prices down further due to economy of scale.
FYI, if you use 4 Li-Ion 18650 batteries, the total voltage would be 14.8V. But the charger comes with the vacuum is 24V DC 210 mA. I am not sure if the charging voltage is too high for the battery.
The link for the battery is for an external charging pack on Amazon and I don’t have the tools (or experience) to do what Mike advised above. Is there by chance another way?
Gently separate—are you kidding. Impossible to pry the thing apart!
I bought a 4 socket 18650 batt holder off EBAY, 4 -18650 rechargeable 3.7V batts off EBAY. The holder plus batts fit perfectly in the space previously occupied by the NICAD pack and I’m back in business easy!
PS, 4-18650 batts equal 14.8 volts and the NICAD pack was 15.6 volts. Mike’s “upgrade” will work perfectly well and within spec all day long.
There looks to be a circuit board attached to the battery. NOT like the picture.
Yeah there's a PC board soldered in. Help?!
Link to Amazon for purchase of said battery pack takes you to a headphone jack!! Where can one get the replacement? Or pitch another POS in the landfill. Such a shame.
4 lithium cells have a MAXIMUM charge voltage of 16.8. The charger for my vacuum is rated at 21V and 100mA. While the charging current is well within the limits of the lithium batteries, leaving the cells charging above 16.8Volts will lead to cell degradation and likely a fire. Secondly, lithium batteries have a minimum discharge current below which attempting to recharge the battery is dangerous (fire risk again). The vacuums discharge circuit is not designed for a low voltage cut out, and will drain the lithium cells below their acceptable operating range. In short do not replace with lithium cells.
Actually, I’d like to start by asking exactly what batteries are used in the dust-buster as sold. Or what are the specs?
Since you can’t buy the battery pack as such, it seems like you have to reconstruct it. (No instructions for that part yet.) The photograph makes it look like there’s seven cells in the original. Is that right? I picked up a model number from one of the photographs: hsd-sc1500p. That led me to 2200mAh Sub C NiCd batteries. Is that the correct initial spec?
Mixed messages here on the Li-ions!
Where do I find the spare battery pack?
I just upgraded mine with 4 removable 18650 batts, removed the back plate cover and mounted the battery holder there. Be nice if I could upload a picture.
I count 7 battery there, so how the voltage get to 15.6?
I bought these batteries from Greenforce eBay seller cells 16 x SubC Sub C 2500mAh 1.2V NiCd Rechargeable Battery with Tab Blue US Stock I couldn’t find any 1500 mHa batteries but these should last even longer between recharge. The important thing is the 1.2 V. When I connected the 13 batteries together it came out 16.75 volts. Some problems I had were that I had to fold over one of the tabs so it could be going the opposite way which allows positive to negative from battery to battery. I’m not sure why they have the tabs going the same direction because it just doesn’t work. Note I used the cardboard separator that was with the original batteries to line them up but it caused the batteries to be too high, so they didn’t fit inside the battery compartment right. I had to grind down some plastic with my dremmel on the top battery supports inside the compartment that holds the batteries in place to make room.
Here are some pictures I took https://1drv.ms/u/s!AoTe_z2joSpEg8FVJ9JK...
I have a Black & Decker cordless Dust Buster. The battery is shot. These instructions look like what I need but the battery in it is lithium type 1, 12v Max DC, 18Wh, 1.5 Ah. Can I use this battery as a replacement? If not where can I get the battery I need? I don't want this to end in a landfill.
Where can I take my portable black & decker vacuum for replacement lithium batteries?
