long island jack Posted January 19, 2022 Share Posted January 19, 2022 Need help, getting error code 97, which is internal battery needs replacement, the battery needed seem to be rare as rocking horse droppings. I've tried a reset which hasn't cleared the error code, any suggestion or a fix for my problem. Link to post Share on other sites More sharing options...
Nigelcliffe Posted January 19, 2022 Share Posted January 19, 2022 I suspect you're being too specific in your search. Soldered in coin cells are readily available. However, several people I'd trust suggest replacing the soldered in battery with a holder to take a CR3032. The battery won't last quite as long (so you'll get seven years rather than ten?), but will be a doddle to replace next time with a standard battery.

ryan1 Posted January 20, 2022 Share Posted January 20, 2022 I had this problem recently and phoned A and H for advice. The gentleman recommended leaving the Lenz unit (LZV100 in my case) plugged in for 4 to 5 hrs to give the internal battery a good charge. This certainly worked for me so perhaps worth a try before doing anything else. 1 Link to post Share on other sites More sharing options...
Jeremy Davison Posted January 20, 2022 Share Posted January 20, 2022 Hi, I had this problem with my LZV100 unit. I found that you can get the proper replacement from Farnell and I took a photo so that I could help others in the Preston club. My unit has worked properly ever since. I hope that this helps you and others Cheers Jeremy Link to post Share on other sites More sharing options...
long island jack Posted January 20, 2022 Author Share Posted January 20, 2022 Sent A & H an email got the same advice, didn't work for me still have error 97, looks like i've two choices, A & H fit new battery or i fit a CR2032 battery holder, will take it to bits, to see how big a job it's going to be and if i'm able to do it.

Crosland Posted January 21, 2022 Share Posted January 21, 2022 I am a bit concerned by the conflict between leaving it plugged in to charge the battery and fitting a bog standard coin cell, let alone a lithium cell to replace a rechargeable battery. 1 Link to post Share on other sites More sharing options...

According to a source I trust, the original battery inside is a Varta CR2450PCB3, which is a 3v lithium with PCB legs. I've no idea why A&H are advising that leaving the LZV100 plugged in could charge such a battery ( just maybe there's another battery which is rechargeable, but that would be an unusual design...). Nearest LZV100 I have access to is 50 miles away, so I can't easily look. The fault code might indicate battery. Or it might be something else. - Nigel Link to post Share on other sites More sharing options...

I had that problem last year. The battery you need is a CR2450-1GU. I managed to find one here without too much difficulty, although they are not exactly common. https://akkushop-b2b.de/de/cr2450-1gu-lithium-knopfzelle-liegend-printausfuehrung-3er-print/ The battery is soldered to the circuit board by three integrated 'pins', making it awkward to remove. I just cut through the pins and then removed the remains individually with a soldering iron. It's then an easy job to solder on the new battery. HTH and good luck with finding a replacement, David Edited January 21, 2022 by Kylestrome Link to post Share on other sites More sharing options...

What's your concern, the unit is on for 6-7 hours at an exhibition and the CR2450 is a non rechargeable battery, there must be something in the circuity of the Lenz lzv100, to stop the battery getting a charge and blowing up, now thinking about the advice given, the 5 hour charge and reset seems a waste of time, if in deed the battery is dead.

Smaller capacity (600mAh vs 950mAh), so will last approx 60% as long as the (no stock) Farnell item. However other (no legs) CR2450's are circa 600mAh, so possibly the no-stock item details are incorrect ? It is almost 3x the capacity of a typical CR2032, with a Varta coming in at 230mAh (Farnell for data). There are holders for normal (no pins) CR2450's, such as this one. But its a lot more expensive at £5 for the holder, then a battery on top of that. https://uk.farnell.com/keystone/105/holder-battery-1-cell-24mm/dp/676470?MER=sy-me-pd-mi-acce - Nigel Link to post Share on other sites More sharing options...
long island jack Posted January 24, 2022 Author Share Posted January 24, 2022 Had a look inside the LZV100 yesterday, looks like there's hole already for a battery holder, (wonder why they didn't add one), instead of a battery, it looks like a straight forward job, once you get the battery out, has any body gone down the battery holder replacement, was it as straight forward as it looks.

The service agent for Lenz was implying that he battery was rechargeable. If that were the case, replacing it with a non-rechargeable would be a bad idea. It now seems A&H are just plain wrong.

Melly Posted March 16, 2022 Share Posted March 16, 2022 Hi, just trying to resolve similar issue and have ordered batteries; A&H don't have any. Is the battery in the handset or the LZV 100 unit ? Thanks. M Link to post Share on other sites More sharing options...

Is the battery in the handset or the LZV 100 unit ? Inside the LZV100. It's a soldering job on the main circuit board, either to replace the existing soldered-in battery with another, or to fit a holder for a clip-in equivalent battery. Fairly simple stuff for those comfortable with such electronics work, but potentially quite scary for others. Link to post Share on other sites More sharing options...
Melly Posted March 16, 2022 Share Posted March 16, 2022 Thanks Nigel. The 5 hour 'recharge' didn't work and I've got a new battery arriving tomorrow. The handset touch pad needs a clean as well, so I'll have them both open I'll guess. I think I forget I bought this system back in 2004 - so it's done really well to survive all these years. Thanks for the reply. Ian Link to post Share on other sites More sharing options...
RMweb Premium melmerby Posted April 1, 2022 RMweb Premium Share Posted April 1, 2022 (edited) The CR2450 with 3 pins is available from RS (in stock) at £1.38 each + VAT (3v 600mA) EDIT Spotted it's already been mentioned!

DaveCurrie Posted July 12, 2022 Share Posted July 12, 2022 The battery in the Lenz is not a rechargable type, the CR 2450 Li-Mn 3v is a higher capacity CR 2032 battery. A suitable replacement can be obtained form "The Small Battery Company" Link to post Share on other sites More sharing options...
