Hi, I posted in the trail cam thread about batteries & the 1.5v alkaline vs 1.2v of rechargeable batteries, some of you might find it an interesting & surprising read. As for the high capacity nimh batteries, they’re not the best as they lose charge constantly even when not being used, you’re much better of using LDR type nimh (Low Discharge Rate, sold as ‘Pre-Charged’ ) rechargeable batteries, yes they have less mah than non LDR batteries but in certain situations they will last longer due to very little drain when not being used, for example during the day when many probably turn off their trail cameras or set it to only be active over night.
I’m finding the amazonbasics rechargeable batteries to be brilliant, using them in my tail camera & the solar powered garden lights. I opted for the 2400 mah, that’s the highest capacity LDR available & I’m getting longer life than I was with the previous 2900 mah in the devices I used them in. I only found out about the low discharge rate variant of nimh batteries last year & after using them for a bit I’ll never go back to normal nimh again!
