WARNING WARING WARING OMS Lithium-ion could put your life at risk.
After my 10w Phantom HID hight seemed to have an issue with holding a charge I did some research in Lithium-ion bats. See http.//en.wikipedia.org/wiki/lithium_ion_battery.
The battery at full charge will irreversibly loose approx 20% capacity per year...and much more if not stored in 40% to 60% of charged and in your refrigerator! My light is 3 years old and based on the info I could find lost 60% of capacity. Did it come on, nice and bright, yes. But did NOT come back on in just 40 minutes of use. (Specs say 270 minutes) I have and read the OMS owner's manual and maintained the light.
Called to order new battery. OMS price over $200.00 I requested the date of manufacture and got run around, requested information on the stated 13.2v capacity stated in OMS Specs because the charger only charges up to 12.5v, got run around. Called dive shop to order light IF they could get the manufactured date. They were told that someone would call back, OMS sent it any way. It came in, IT was 2 years old. So they want to sell a battery which the capacity could be 40% to 80% less depending on how OMS stored the battery as new. PROBLEM, you plan your dive accounting for half of the stated Burn time of 270 minutes, your light is 3 years old and 60 minutes into your dive your $1,000 lights fails. Or you buy a "NEW" battery from OMS not knowing they are selling old batteries. Your back up floods and your 3rd, well you just did not bring it. Have a nice dive.
I could not get info from OMS and OMS told the dive shop was told I was wrong. OMS denied any issues with the Lithium-ion batteries with capacity because of age.
Now what can I do with a $1,000 light when OMS will only sell old batteries which can fail deep inside a 200 foot 60 year old mangled wreck?
The thing is OMS just did not care and SEEMS to want to put profit above safety
