Battery needed??


13 Feb 2018 6:12PM
Hi,

I have this praktica super tl1000 but the battery is flat so I was wondering if a battery is need to take pictures because I read it's only for the flash and light meter.

The automatic exposure control system is powered by a mercury oxide battery type PX 625 or another type meeting the same specification, of a rated voltage of 1.35 V.

Does that mean I can still take pictures even though the battery is flat

Yes, The camera works mechanically. The battery only operates the meter. This will help you http://www.butkus.org/chinon/praktica/praktica_super_1000/praktica_super_1000.pdf

You need a Wein Cell MRB 625.

Most of the other newer mercury equivalent replacements batteries are rated at 1.5v and can throw the metering out.

The 1.5v batteries can be worked around but without practice its an extra hassle.

Not a very nice remark to nikonphotographer, who is trying to be helpful to the OP.

Battery voltage doesn't always affect the meter reading.

Some cameras, like the Pentax Spotmatics, use a null method where the needle is centred for correct exposure: a Wheatstone Bridge circuit for the techies. In such cameras, the battery voltage is irrelevant, provided it isn't high enough to cause damage, so any battery of the appropriate size can be used.

Does the OP's camera also use the null method?.

Lol who knows, its a better to be safe than sorry if your unsure, or use without battery and use your head or a separate light meter.

Good god man, whatever (as in what ever source) that was all.

If you really do want to nit pick then maybe you should check out ebay, they might be even cheaper from there and then post some links Smile
