10x30is II can you use rechargeable batteries? (1 Viewer)

The Lidl batteries are a bargain, but the shame of traipsing along the Lidl aisle of dreams was almost too hard to bear. But I did and they are superb……and cheap.😆

Got an IKEA near where you live? The Ladda is an excellent NiMH as good as the Eneloops IMO.

There is one about 70 miles away, sadly not further!

I hate Ikea with a passion buying stuff designed by Sven Björn ArschIoken which I never knew we needed until we joined the long trail of the bewildered following the foot outlines on the floor through every department. Hate to be caught up in a real evacuation emergency.

The batteries are great though, it was said that they were Ikea branded Eneloops and I bought some years ago from the Kaarst store. Still hold a charge.

Hermann,
It appears that Amazon sell Ikea Laada 2450mAH in packs of 4 for £12.46 with free delivery if you have Prime.

When I was using speedlights at weddings the flash performance with NiMh batteries was erratic. I learned about the ZTS pulse load battery tester and bought one and used it to test all my NiMh batteries. Often in a set of 4 batteries one would be at 60 and that was enough to pull down the total voltage of the set. Some of the bad batteries were new or only recharged one or two times.

Not all NiMH rechargeables are created equal. Get good quality NiMHs like the Eneloops (or the IKEA Ladda) and you won't have any problems - provided you use a good charger and treat them resonably well. I've been using Eneloops in my flashguns for many years. No problems.

NiMh batteries also self discharge fast enough that I needed to recharge them each time before use. After 30 days there could be a drop of 20% or more. When I switched to power tools that used lithium battery packs it was great to be able to grab a tool that may have been sitting in a drawer for two months and to have enough charge left for use that day.

When did that happen? 20 years ago? Low-discharge NiMH rechargeables are at about 80% minimum after a year. I actually tried that with that very first batch I got when the Eneloops appeared: I charged two Eneloop AAs fully and put them away for a year. 15 months actually. Did a discharge/charge cycle afterwards. They were still at a bit over 80% charge.

Voltage levels are more important than most people appreciate. When the first electronic cash registers and personal computers were introduced they had very large motherboards and the voltage at the far side of the board from the power supply would not be sufficient. Engineers starting using 6 volts DC instead of 5 volts DC from the power supply to compensate for the drop in voltage. Digital devices use voltage levels to differntiate between 0 and 1 and this requires a voltage sufficiently greater than the ground state for the devices to operate properly.

In what way is that relevant to the dicussion here?

BTW, Canon specifies the Canon 10x42 L IS can be used with Lithium batteries, NiMH and alkaline batteries in the manual. The runtimes according to Canon's tests are in continuous use:

Size-AA lithium batteries
Approx. 8 hours (25˚C / 77˚F)
Approx. 3.5 hours (–10˚C / 14˚F)

Size-AA Ni-MH batteries
Approx. 6 hours (25˚C / 77˚F)
Approx. 2.5 hours (–10˚C / 14˚F)

Size-AA alkaline batteries
Approx. 2.5 hours (25˚C / 77˚F)
Approx. 10 minutes (–10˚C / 14˚F)

Also, Canon mentions in their manual what happens when the batteries are low: "When the battery power is low, the Image Stabilizer may generate noise and vibration. The image stabilization is not affected by this."
