Ok, so I'm good for possibly the next three years with my AGM's. I plan to keep on top of battery maintenance so I hope I'm being realistic.
When it's time to replace my batteries I hope to move to NiMh or even maybe something else, battery technology is moving along about as fast as my MB-1-E.
I use NiMh for anything that needs a rechargable battery in my house except for the laptop and the cell phone. They seem to do well and last quite a while and are relatively easy to recharge using my AccuManager Charger.
My question is related to Amp Hours.
I currently have a 24V-36Ah battery bank on the MB-1-E.
These are of the SLA type.
Do I need 36Ah of NiMh to get the same out of my battery bank? I think probably not.
The reason I have 36Ah with the AGM's is so I don't deplete them more than 50% (or less) so that they will last a while.
It's my understanding that the NiMh will run nearly to depletion without harm.
I'm guessing that I can use somewhere around 20Ah of NiMh to get the same range from them.
Does this sound about right?
What about charging?
I assume the charge time will be a bit longer for this size bank of NiMh.
When purchasing NiMh, what's the best way to get the most Ah/$ ?
I use CTA 12000mah D-size for my most used battery operated lights. They take a while to charge but boy do they last a long time. I'm very pleased with them for that application.
Purchasing 40 CTA 12000mah D-cells (this would give me 24Ah@24V) is pretty darn expensive. We're talking over $500 if my calculations are correct.
Just looking for some advise on cost effective alternatives to the AGM's for my next battery purchase.
Thanks for any light you can shed on this (pun intended). :)
