Petzel Tikka XP + Rechargeable AAA?

[marxs]

Im getting confused...on the one hand the website says its a no-no, others have used it ok, and my manual says i can use rechargeables...what gives?:huh2:

Does the manual really say it's OK? The official line from Petzl seems to be it's a no-no, due to the fact it is unregulated and so relies on the internal resistance of the cells. In reality I suspect a Tikka XP may be OK provided you don't use boost mode as the normal current is so low, but personally I wouldn't risk it.

Cut and pasted from the Tikka XP manual on the Petzl website:

Batteries
Use alkaline batteries or NiMH rechargeables.
Do not use the lamp with Lithium batteries; due to recent advances
in their performance characteristics (especially their higher output
during discharge), they can cause the lamp to overheat and possibly
damage the LEDs.

my manual says the same thing. i rest my case then...rechargeables it is...unless someone can tell me they have had problems with them before.

Using Ni-MH rechargeables is no problem at all.

Checked back, and the warning I remember was actually about lithiums, so I completely and happily retract my previous post!

btw, hows the runtimes using alkalines vs nimh? ive heard the output is really poor using nimh

 

[AndreasB]

As far as I can gather the duracell AA is about 1500-1600 mAh.
My Sanyo Ni-MH's is about 2700 mAh, which should give a far better runtime using Ni-MH.

I haven't seen any change in light output when swithing to Ni-MH's.

I've been using SANYO 1000 mAh for about a year...very satisfactory runtimes (sorry, no charts or beamshots).
