The model number of your Sonicare toothbrush is marked on the lesser of the handle.

For other toothbrush models the battery replacement process is slightly different so please encounter our other guides to toothbrush battery replacement instead.

The basic method is:

• Open and dismantle handle

How-To

To starting time with, remove whatever brush heads from the superlative of the handle. To soften upward the plastic of the handle you can stand the toothbrush in a cup of hot tap water (most 60 degrees C or 140 degrees F) for 5 minutes before starting. This should make opening it up easier as the internal clips should flex more easily.

Tear off a strip of duct record most 15cm (6 inches) long and stick it effectually the circumference of the handle right at the bottom, up to the edge.

Cutting two pieces of paper-thin the same length and width equally the duct tape and wrap both over the elevation of the duct tape. Set them in identify with another piece of record. Together the cardboard and tape will protect the toothbrush handle from impairment by the grips.

Place the grips right up to the bottom border of the handle and clasp the handle firmly across the widest part of the base of operations.

Release the grips, rotate the handle a quarter of a plow then clasp the grips over again.

Continue releasing the grips, rotating the brush by a quarter of a plow and then squeezing with the grips until the base cap pops out a few millimetres. You lot can then lever the cap out with the screwdriver.

At that place are ii black plastic tabs holding the workings of the toothbrush in identify by engaging on the inner wall of the handle casing. These tabs can exist released by poking downwardly inside the casing using the small screwdriver and moving them away from the inner wall of the handle casing (arrowed below). Likewise run across below the sneak preview of the dismantled toothbrush with a plastic tab arrowed then you can encounter what you're releasing. You tin can slide the screwdriver in merely in a higher place the blackness plastic block to release the clip.

Push the handle down hard, shaft get-go, onto a solid surface. This might mark the surface and then use a scrap of woods or something outdoors! The inner workings of the brush should start to slide out.

Fully slide out the innards of the toothbrush.

Remove the protective blackness rubber spacers from both sides. First the circuit board side:

Then the battery side.

You tin can see the original bombardment in-situ. This DiamondClean is fitted with a Sanyo battery. The label shows part number POHC P/N 4235 010 13068, Battery Mfg Sanyo and Blazon Li-Ion on it. Yours might have a dissimilar label showing a different part number such every bit POHC P/N 4235 010 15362 and/or Battery Mfg Sony just it should still be a Li-Ion type (Lithium-Ion.) The Sony and Sanyo batteries are interchangeable then yous tin can fit either to your toothbrush. The Sanyo batteries nosotros supply are higher capacity so they volition run for longer before needing to be recharged.

There are three solder points that we're interested in. The positive bombardment concluding, (arrowed below)

The negative battery terminal, (arrowed below)

And JP1 which disconnects the battery (arrowed below.) This is very important due to the volatile nature of Lithium-Ion batteries. It besides takes away some run a risk of shorting out the battery when we remove it.

Warm upwardly your soldering iron and using a solder sucker, braid or merely by carefully moving the solder blob break the join betwixt the ii pads of JP1.

Using the solder sucker or complect, de-solder the positive battery final and then that the metallic pivot tin be moved inside its pigsty. You might notice that yous need to simultaneously pry the battery out slightly at that end while the solder is molten to brand sure the solder doesn't solidify back onto the solder tag.

In the same way, using the solder sucker or complect, de-solder the negative battery terminal and so that the metal pin can be moved within its hole. Once more, you might find that you need to simultaneously pry the battery out slightly at that stop while the solder is molten.

Remove the one-time bombardment from its holder and make clean upward the holes in the excursion lath to make sure they are clear of solder, ready for the new battery to be fitted.

Compare your original bombardment to its replacement. This is a 49mm long by 14mm diameter 3.7V Lithium-Ion battery. Also available in light-green! Please support us with writing these repair guides by ownership your replacement battery through our secure online store hither at ToothbrushBattery.com. Note the groove around the circumference of each battery – this is at the positive end of the battery.

Positive terminals:

Negative terminals:

Insert the new bombardment into its holder with the pins at an angle so they line upwards with the holes in the excursion board. Brand sure you become the polarity (+/-) right! Remember that the groove around the circumference of the bombardment is at the positive stop.

Push the bombardment right into its holder so the pins become through the circuit lath.

Turn the brush over so you can run into the circuit lath.

Making sure that the battery is still firmly in its holder, solder both battery pins in place.

Using miniature side-cutters cutting the pins off merely to a higher place the solder joints.

Re-bring together the two solder pads of JP1.

You might find that some of the (very vivid!) LEDs light up at this stage. You tin likewise hold the toothbrush over its charger for 10 seconds to verify that it starts to charge up correctly.

Re-fit the protective rubber spacer over the circuit board, ensuring the moulded clips at the sides become over the circuit board.

Re-fit the protective rubber spacer over the battery, ensuring the moulded clips interlock with the plastic frame.

Advisedly but tightly agree the toothbrush around the safe spacers. You lot can now effort switching on the toothbrush to test it by pressing the power switch arrowed below. Be enlightened that it volition vibrate strongly! Switch it off again later on a second or two. The LEDs might stay lit for a while after testing.

If the brush will not switch on go back and bank check your soldering of the battery connections, the soldering of JP1 and that the battery was fitted the correct way around. Also cheque that the charging light comes on when the toothbrush held over the charger.

Slide the inner workings back into the handle casing. Make certain the innards are the right way up and that they slide in easily forth the alignment splines moulded inside the casing. The inner workings should slide all the way in.

Line upwardly the tiny grooves in the base cap (see below) with the splines in the casing (they are at the dorsum of the casing) and push the cap in. It should click into place.

Yous should at present accept a fully repaired and reassembled Sonicare DiamondClean toothbrush! Put the brush on to charge for a full 24 hours and check that the charging light starts to wink. Please recycle your old battery either at a local civic amenity or a supermarket drove point.
