I have an XR200 DMP alarm panel and need to replace the backup batteries which currently are 2 Genesys (Yuasa) NP7-12 batteries (12v, 7Ah), each fed by a separate 16.5V 40VA transformer and charging circuit.
The manual says: "Use sealed lead-acid batteries only: Use the DMP Model 367, 12 VDC 7.0 Ah sealed lead-acid rechargeable battery. Batteries supplied by DMP or manufactured by Eagle Picher or Yuasa have been tested to ensure proper charging with DMP products."
- Is there any reason I couldn't use a 12V battery SLA battery with a similar form factor but higher Amp-hour rating, particularly since per DMP each 40VA transformer can support up to 2 batteries? In particular, there are some batteries that are rated at 9Ah that would still fit in the existing enclosure (e.g, PowerSonic PS1290 rated at 9Ah (see:
- More generally, is there any reason that other non-Yusa SLA with equivalent electrical specs could not be used? (despite the manual saying the panel was only tested with Eagle Picher & Yuasa) SLA batteries seem to be pretty comparable and brands like PowerSonic seem to be reputable. In particular, in addition to looking at the PS1290, I am also looking at the PS1270 which is a 12V 7Ah battery that has near identical electrical specs to the Yuasa battery but is a fair bit lighter and smaller.
Thanks so much for your kind assistance!
