Werker SLA batteries? (... better than PowerSonic?)

I will no longer use them in medical devices. I use Werker batteries and they last far longer and work much better. As the name implies they must be made in Germany and just like a VW, run forever. |

As the name implies they must be made in Germany and just like a VW, run forever. The best but equally expensive are the Sonnenschein dryfit batteries, made in Germany, par non. I ran 14v 10 ah for many years, and have a pair back from 2005 that I will still occasionally put on charge and do an hour or so locally. Of course for longer flights I will use newer ones (and also some LiPo ones, equally reliable). Sonnenschein dryfit NEVER failed me. These are also hard to get but obtainable. If need be, I can post a source. |

Now Batteries + Bulbs, and have apparently dropped the name Werker. If you blow the picture at the link up, you can clearly see this Werker SLA is "made in china" - - probably at the very same factory all the other 12 volt 7 to 10 AH SLA's are made! http://www.ebay.com/itm/WKA12-7F-12V...-/191412460050 Switching to LiFePO4. bumper |

Switch to Lithium Iron Phosphate Batteries. The chemistry does not supply it's own oxidizer like the Lithium Ion batteries in you laptops, so it's much safer from a fire hazard point of view. Yes they cost more up front, but they last longer so in the long run they end up costing less. I'm still running the original K2 batteries that were the subject of my battery article in Soaring sever years ago. They still work fine, no battery issues since the switch. The electronics, and especially the radio like the fact that the voltage never drops below 12V, after 5 hours in the air with a full panel of electronic gizmos.

6PK, can you post your source for the german Sonnenschein batteries? It's probably time to obtain another replacement since I've been flying with one for 6 years with no problems. I use a 10ah,12v unit.
