Not too many, but not too little either. Let's see...
R LiIon:
7 18650s (6 AW 1 Pila/Wolf Eyes)
4 RCR123s (2 BS 2 AW, one AW not useable)
6 14500s (4 are LiFeP04)
2 AW C LiIons (one seems to have crapped out)
1 KD Protected D
R NiMh:
14 LSD AAA NiMh (6 Ray-O-Vac, 8 Eneloop)
24 LSD AA NiMh (eneloops)
20 High Current AA NiMh (Titanium 1800)
14 NiMh D (4 Tenergy, 10 Chinese nameless recovered from a batt pack)
plus a few 5+ year old Ray-O-Vac AAs that still function relatively well in odd devices like my toothbrush
R Alkaline:
14 decently performing Ray-O-Vac Alkaline rechargeables (from back in the day).
Primaries:
5 CR2
20 CR123
16 Energizer L91
+ a few left over Alkalines in C, D, AA and AAA... not worth much except in an emergency. Need to stock up on more L91s.
So (almost) enough, but not an overwhelming collection yet.
Looking for a nice high capacity but portable SLA with 12V plug and inverter still. Need to get some LSD C and Ds. Hoping for some IMR D's soon.
