AFFECTED: 48-11-XXXX Ni-Cd ‘Slide-On’ Battery Pack,
48-11-XXXX V™-technology Li-Ion Battery Pack
SUBJECT: water damage indicators – voided warranty
WARNING! NEVER ALLOW A BATTERY PACK TO BE IMMERSED IN WATER!
Milwaukee’s Limited Warranty does not cover a no-charge warranty adjustment on any battery pack which has been submerged and
exposed to water.
Determining a Water Damaged Battery Pack
• Battery Packs have internal cells and connections that can become
corroded or ‘short-out’ when water enters the case through the battery
packs power connection terminal opening. As with a vehicle that has
been submerged in water and has or had water in the engine cylinders,
causing damage when the engine is turned over;
the same can be said
of a Ni-Cd and V™-technology Li-Ion Battery Packs - a battery pack
that has been submerged in water will exhibit lower power and have
reduced capacity to be charged or become non functional.
• Milwaukee battery packs have no serviceable internal components and
must therefore be replaced under such conditions.
• By and large this condition can occur when a cordless Sawzall
®
is used
to cut pipe that contains water but, is not limited to this application or
tool – coming in contact with a heavy rain and a flooded tool box,
dropped into a puddle, etcetera can allow for water to enter into the
battery pack through the pack’s power terminal opening. To avoid problems, immediately remove a battery pack that has been
exposed to water and turn the battery pack on edge to expel any water present.
• Determining if water in a battery pack is the reason for lower power, a reduced capacity to be charged or it being non-functional
can generally be seen by the tell-tale signs of mud/water stain on the outer shell of the pack, especially in the packs slide-on
connection area
(see photos) . Additionally, when opening a pack a water stain on the paper covering a cell can be seen along
with corrosion to internal terminals. In a few instances a water-line mark on the inside of the case can be found.
