Last year bears became much more prevalent near some of my bee yards so I started installing solar charged fencing for protection. This past summer things worked like I charm and the fence was pegged at 9900V every time I visited. No issues. Last week however I went out for an inspection and noticed the charger wasn't functioning. I brought the battery back to the shop and put a voltmeter on it and it was dead as can be. I charged it up again to 14.0 V. but it appears that the battery isn't holding a charge like it should. This was installed in July 2018. I am needing to purchase (3) more setups and now I'm having second thoughts about buying (3) more Parmak units if the batteries have issues? Initially I read several of the threads on here giving the Parmak Magnum rave reviews. However a few reviews on Amazon indicated that the batteries died prematurely like mine did. I'm looking for some feedback from other Parmak Magnum 12 owners about their thoughts. I don't want to be buying new batteries every 6 months for a unit that should go 2-3 years on the original battery. I know my unit is warrantied for 3 years but that's not the point, as I now have to send the battery back and wait for a replacement. Feedback please.
