| + | [title] Swap Batteries - The hardest step |
| [* black] Replace the batteries with (2) AAA Ni-MH rechargeable batteries | |
| - | [* icon_caution] Make sure to correctly align the polarity of the batteries, as noted on the housing! |
| - | [* black] Put the metal tabs and connector on the new batteries |
| + | [* icon_note] Philips should have just made this unit with a battery compartment that allows the user to replace the batteries. Or at least used a spring loaded case that allows new batteries to snap in - but the batteries are spot welded onto the wires! This makes this step quite difficult. |
| + | [* icon_caution] Be extremely careful not to damage the red and black wires. If you mess around too much they will break and you will have to find another way to solder them back on. Work out where they connect to now so if you do break them you have a hope of putting them back on. |
| + | [* icon_caution] Make sure to correctly align the polarity of the batteries, as noted on the housing! ***If your batteries get hot all of a sudden, it is because you are shorting them or have wired them wrongly.*** |
| + | [* black] Solder the tabs onto the batteries. You may be able to get away without soldering the link between the two batteries but remember the vibration this unit generates. Soldering these batteries is difficult and if the join is bad it will break with vibration. |
| [* icon_note] The wires/connectors can be held in place by pressure from the batteries (or optionally soldered) | |
| + | [* icon_note] The batteries my body groom were actually flat at the negative end AND flat at the positive end. Therefore 2mm shorter than normal AAA size! This made it impossible to fit the new ones. I got around this by chopping the nobs off the batteries with a pair of side cutters (a rather desperate measure that seems to have worked). |
