Is 4.25v end charge too high for Imr hd batteries?

[lithiumdaze]

my tf tr 001 takes my all my batts to 4.25v at end of charge. Is this too high for high drains? any li-ons?

no, 100% normal. That means it is fully charged. Any 3.7v batt that is fully charged, reads 4.2x volts on a multimeter. Do not worry about this at all.

I believe most manufacturers recommend 4.20V max.
Also, the higher the charge voltage, the shorter the lifespan of the battery.

is that worse for high drains and regular li-ions alike? if i put my meter in with the +/- terminals and sit there and wait till the batt hits 4.2v dead on will that help or do i have to remove the battery and then check the voltage. are pila chargers worth the extra coin in your opinion? thanx for the help!

Pila's are very reliable. I do not own one. I have an Ultrafire WF188 that reliably terminates at 4.16V. Undercharging is much better for cell life.
Pulling the cell off the charger at 4.20V should be fine. I do not know if metering a battery while charging is accurate. I pull them off.
