if it has regular water for its battery operation, you 
can recharge it but it will generate a few stray "hydrogen"

if you use newer "gel cell" batteries ( no water ) than
maybe its safer, but not as much wattage/amperage

"sealed batteries" still leaks some hydrogen

- recommended for smokers, houses w/ gas heaters, gas stoves,
