The DG813 works over a distance of 150m (500ft) providing full operation in a single set-up between manholes. The DG813 has a grade range from -12% to +40% and is fully self-leveling over the entire grade range. The length of the DG813 has been reduced to make it easier to set up the lasers into tight inverts in the manhole. One thing I do is remove the batteries in the laser and receiver when not in use for the winter.Benefitting from the latest technology developed by Spectra Precision, the DG813 delivers an unprecedented performance when laying pipes. It has the visible red light, maybe newer model don't use as much power as the older ones do. It seem to last a long time on 4 Dell cell batteries. Now, I have a laser for my part time business, think it's a Spectra 1242. Note: The model we had was a 12Volt one and was an older unit. We just used a very good set of D cells and kept spares in box. Too costly first of all, and won't hold charge. When I worked for a excavating company, we kind of gave up on rechargeable batteries.

It's a safety switch to protect the unit from charging regular batteries. There is a little microswitch down in the battery well and a knob on that cage that pushes the switch letting the unit charge. If you are replacing the originaly batteries with new rechargable ones you will have to put them in the little plastic cage for it to work. It says right in the manual not to use the charger with regular D cell batteries. Posted 07:18 (#5679223 - in reply to #5678637) Subject: RE: Spectra laser battery charger, 6 volt? The regular d cells are generally quite predictable and if you keep track of hours used, you know when to grab (4 ) spares. ) had lots of Spectra Lasers and eventually the batteries would not hold for a days work, our work around was to buy regular d cells and to carry spares. Likely that the original rechargeable batteries are going bad, as suggested replace with batteries that match original construction.

Those power supplies are designed to run a device, not recharge batteries, so good chance you need the correct factory charger or at least one designed to charge the size and type battery you use outside of the device. Your charger may be designed for a certain type of rechargeable battery, Ni-cad, Ni mh or Li ion Make sure the replacement batteries are the same type and capacity as the originals.

They would have to be rechargeable I would think to recharge, but I'd think they would work untill they went dead.

Will any 6 volt output charger work for this application if my factory charger failed? I don't know if my charger is broken or the original batteries were bad.ĭo the batteries have to be "rechargeable" for this application to recharge? The batteries were rechargeable 4 D and were original until I replaced them with some more common Duracells. Posted 21:00 (#5678637) Subject: Spectra laser battery charger, 6 volt?
