Is a trickle charger good for a battery?
Trickle chargers are especially useful if you have an older car, a weaker or older battery, or just want peace of mind. Trickle chargers work by releasing a small amount of current to match a battery’s natural self-discharge rate to keep it topped up at its fully charged level.
Why is my solar panel not charging my battery?

How fast will a 100 watt solar panel charge a battery?
A 100 AH battery will only give you about 40 minutes at 100 amps of usage. You can use amp-hours to figure out how fast your battery will charge as well. For a 100 watt solar panel, we already know that it produces 8.33 amps. In this case, 1 amp of current flowing for 1 hour charges the battery by 1 amp-hour.
