Maintaining the O-Ring

The battery pack for DS125, DS160 and DS161 strobes is designed with the most reliable, user friendly sealing method possible. If maintained, it is virtually impossible to flood a battery pack.

The o-ring is a compression seal. It does not need to be lubricated and requires virtually no maintenance. In fact, we recommend that you do not remove the o-ring from the battery pack unless you are replacing it.

If sand, dirt, or debris is on the o-ring, wipe it off without removing the o-ring from the battery pack. Unless the o-ring has fallen off, it is not likely that any debris got underneath it. Use your finger or a clean, lint-free cloth. Use the tiniest amount of Ikelite silicone lubricant only if there is stubborn lint or dust that won't come off of the o-ring.

Flooded Battery Packs

If you have flooded the battery pack, discontinue its use immediately. Using a water damaged battery pack can be hazardous and may short circuit your strobe front. DO NOT ship a flooded battery pack. Please dispose of the battery pack at a local facility capable of properly recycling batteries. Purchase a new NiMH battery pack from your local Authorized Ikelite Dealer.

NiMH Battery Packs

  • Manufactured 2005 - Present
Ikelite NIMH Battery PacksLabeling changed from dark gray (left) to white (right) in 2016; No change in battery specifications

Nickel metal hydride (NiMH) battery packs are the most prolific and most reliable battery packs for reliability of use in a variety of conditions with high or low temperature conditions. They age gracefully and hold up well to both frequent and infrequent use.

Storage Recommendations

Always store your packs in a dry location at a temperature of less than 30°C (86°F). Approximately 20-40% of the packs capacity will drain when left idle for a month. The lost capacity will be recovered after two or three charger/discharge cycles. Cycle the pack every 6 months during long-term storage.

In a pinch, NiMH battery packs can be charged with li-ion chargers but we do not recommend it because charge termination protocols are different between the two chemistries. NiMH battery packs should never be charged with our original NiCd charger (see below) which can overheat and permanently destroy the cells.

Li-Ion Battery Packs
  • Product numbers 4067 (1st Gen) - 4067.2 (2nd Gen)
  • Manufactured 2012 - 2016
  • No longer available due to a long-term shortage of cells

Lithium ion (li-ion) battery packs are the highly desirable because of their high energy density. However, li-ion chemistry naturally degrades over time and is more sensitive to use in extreme temperatures—particularly heat.

There is no practical difference in capacity or use of 1st and 2nd Gen Li-Ion battery packs. 2nd Gen battery pack features updated circuitry which supports newer safety and charging protocols.

Storage Recommendations

Always store your packs in a dry location at a temperature of less than 20°C (68°F). Lithium ion batteries by nature lose a small percentage of their capacity per year, whether they are used or not. This loss is non-recoverable. For best results, we recommend cycling (discharge/charge) at least once every 6-12 months and storing at around 50% charge.

End of Life

Li-ion battery packs do not degrade as gracefully as NiMH batteries. Once one or more of the cells inside of the pack drop below a certain cut-off voltage, the pack will stop working completely or only provide 10-20 flashes per charge. This is a required safety feature for high powered li-ion packs.

We are no longer able to offer replacement li-ion battery packs due to a long-term shortage of available cells. For a limited time, we are running a special exchange program for customers needing to transition from li-ion to NiMH cells.

Within North America, the exchange can be arranged by sending the packs to us via UPS or FedEx ground service. Since transportation of dead lithium ion batteries via air service is prohibited, we ask that customers outside of North America contact their nearest Ikelite distributor to arrange for the exchange.

For safety reasons, li-ion battery packs cannot be charged by NiMH or NiCd chargers. 1st Gen and 2nd Gen chargers can be interchanged in a pinch, but this may reduce the lifespan of the battery pack.

NiCd Battery Packs
  • Product number 4066
  • Manufactured 2000 - 2005
Ikelite NiCd Battery PacksNiCd battery packs had no labeling or date codes

Nickel cadmium (NiCd) battery packs were beloved at the time for their durability in a wide range of temperatures, but were ultimately discontinued because of environmental regulations.

Storage Recommendations

Ni-cad batteries will loose approximately 2% of their charge per day. Recharging after thirty days will assure a full charge before use. The pack should be charged at least every three to six months if not used. Do not leave a pack completely discharged.

End of Life

We do not re-cell or exchange NiCd battery packs. Please dispose of your dead battery pack at a local facility which is capable of properly recycling batteries. Newer NiMH battery packs and chargers can be used with your existing DS125, DS160, or DS161 strobe front without modification.

  • Product numbers 9457.63 (black) - 9457.64 (gray)
Ikelite Toggle Replacement LocksBlack toggle (left) for NiCd and NiMH batteries; Gray toggle (right) for Li-ion batteries

Toggles bear the brunt of the force required to waterproof your strobe and may wear out after several years of opening and closing. To reduce this strain, we recommend detaching your battery pack from the strobe front prior to storing the strobe for extended periods of time.

A 1/4" nut driver is required for the replacement of a battery pack toggle (not included). Alternatively, you are always welcome to return the battery pack for necessary service and testing.

The black toggle is featured on NiMH and NiCd battery packs. The gray toggle is featured on Lithium Ion battery packs.

Problems with Intermittent Power

We call the gold contacts on the battery pack "receptacles." These can loosen over time as the battery pack is removed and replaced over and and over. If you're experiencing intermittent loss of power at depth (evidenced by the ready light going out when the pack is good and fully charged), then loose receptacles may be to blame.

To tighten, use a very thin flat screwdriver to gently bend the 4 four prongs of the receptacle very slightly towards the center. Repeat on all 5 receptacles.
