Hello,
I'm looking for any suggestions for a good set of AA rechargeable batteries.
I have a gps navigation handheld unit that uses AAs, plus other mobile handheld equipment that uses AA batteries.
In the past I've used standard non-rechargeable AA batteries and looking for any suggestion for longer lasting rechargeable batteries to use for extended use in off-grid environments (no shore power for months at a time)
Only power available would be vehicle 12 volt battery or possibly a solar panel.
I have a a couple cylindrical cell 4x lithium/nimh chargers that use a 12 volt power source and have been looking at various 4x and 2x USB powered cylindrical cell chargers such as the LiitoKala 2x and 4x Lii-402 Intellicharger (USB (5 volts) charges both nimh and lithium cylindrical cells.
After looking around for nimh AA rechargeable batteries I come across deals on eBay, such as e.g.
RECHARGEABLE, AA Batteries, 4 Pack, 2450mAh NiMH (1.2V) CVS brand
* Tenergy Premium AA 2500mah NiMH Rechargable Batteries- 4 Pack
EXPOCELL MH90204B - 4x AA NiMH Rechargeable Batteries 2600 mAh 2.6Ah Manufacture year 2016 card pack
4x EBL 2300mAh AA Ni-MH Rechargeable Batteries
* Duracell rechargeable batteries aa 4 pack long life ion core 2500 NiMH 1.2
and others
I'm uncertain what to look for except perhaps a name brand such as e.g. * Duracell and Tenergy ?
I suppose I could just purchase a large pack 16, 20+ pack of non rechargeable but thought I would give the rechargeable AAs a try again. I've had a few AA rechargeable years past (some came with a charger) but most, even the named brand ones, bit the dust sooner than expected. ( less expensive imports last perhaps an ~hour or so with less demand current). I eventually switched back to non-rechargeables, but now again, want to try some rechargeable AAs and looking for any suggestions. As the market is flooded with inexpensive rechargeable batteries, some rated at ~2000 & ~3000 mah and higher I've measured their actual capacity to be somewhere between ~150 to perhaps ~400 mah maximum.
I've also thought about the 14500 Lithiums (approx. or same size as AA with and without protection circuit) However these are much more expensive and have less capacity than many NiMH AA's. Most I've looked at use a ~4 volt cell that's converted to ~1.2 volts and require a proprietary charger.
The better ones on the market are manufactured by KENTLI, run just under $50.00 with charger and shipping for a pack of four. (~$9.25 each for a pack of four.)
