Sealed Lead batteries
Hi folks
I plan to use two Yuasa NPO.8-12 12v 0.8Ah gelcells for portable radio amateur rig.. I will use them in France where power is 50 Hz. I see that chargers available here in Canada always specify 60 Hz. So, do I have to expect some problems? Thanks Pierre |
Better find a charger that works on both because on 50 cps you need more
iron in conventional charger but a switcher will probably be OK since the first thing it'll do is conver the ac to dc. -- 73 Hank WD5JFR "Pierre Desjardins" wrote in message ...

He didn't mention how fast he wanted to charge the batteries. Many older
camcorder chargers were 12 volt and have universal inputs. Would be easy to modify and most thrift stores have them. Al WB7NXB "Henry Kolesnik" wrote in message . com...

Puisque que ce n'est pas de la puissance mais le cycle de phase du courant dans les lignes d'alimentation. Ce qui est important c'est la tension en entré du chargeur!!! - habituellement en France tu as une alimentation en 220V biphasé - ICI au Quebec on a une alimentation domestique en 120V monophasé et une alimentation de puissance pour les chauffages ou certain appareils comme la secheuse a linge en 240V biphasé Alors avec un petit peu d'imagination, un tournevis et deux ou trois morceaux tu peu brancher ton chargeur ICI sans risque pour tes batterie juste surveille le chargeur pour qu'il ne chauffe pas trop. !!!! 73 VA2SCH Daniel |

Various articles on the web for converting a PC power supply to a 12V voltage source. It may have more ripple than is tolerable for a direct circuit, no problem as a battery charger.

not the best way to get the maximum life and longterm charge out of many SLAs, which is why many specialized chips and charging systems have been built, and articles available in QST and online. I picked up a surplus UPS last weekend, with SLA specialty charger, 300 watt sine wave inverter, and battery in the case (for $3 - guys were tired of hefting them around ;-). Even if you had to pay $20 for a surplus unit at a computer recycling shop somewhere, you would still be ahead on the battery, SLA specialty charger, and 12 vdc to 110 AC sine wave inverter You just have to look at a used UPS for what it really is, subsystem wise! One nice feature is you can route out the charging connections to other batteries, making it easy to use the setup in an emergency with other (larger) batteries. Last month's local sale (http://people.smu.edu/arc/sidewalk.html) turned up a 12v 33 amp (400 watt/hr) battery ($5 IIRC). We previously picked up some 12vdc SLA gel cells with 7.8 AH capacity, which are handy for handitalkies, QRP rigs, ATV video cameras, and the like (again, prices were in $3 to $5 range). I'm now looking for some buys in used generators for our club (any hints? ;-) for field day. To my surprise, Sunday's paper had a 3.5 kw AC/DC OVH generator at Pep Boys for under $300, but I'd like something in the 1.5 Kw or less range for easier portability for field day and on-campus emergency power demos. hth bobm -- ************************************************** ********************* * Robert Monaghan POB 752182 Southern Methodist Univ.
